Gasoline from Algae Will Replace Gasoline from Oil

Biodiesel Expansion — Sat, 13 Sep 2008 18:48:08 +0000

We're living in a time when depending too much on oil for energy needs could prove tricky.

That's why now the research on biofuel has been rerun.

Biofuel can be achieved from almost any organic product, from agriculture wastes to dung, including that of wild animals. Now researchers retake in account algae-based fuels, being helped by the recent advances in genomics and biotechnology.

Algae are a natural oil-producer, offering multiple paths to biofuel. They can easily be genetically engineered to achieve varieties that generate high amounts of oil that can be turned into biocrude and refined into gasoline, diesel, and jet fuel; those with less carbon atoms can be processed and fermented to make ethanol.
Algae can be grown on land outworn for other crops and using water unsuitable for agriculture purposes, they do not interfere with food production, and oil-per-acre production can be much higher than for industrial crops like soybeans. And their oil production can be boosted even more.

The National Renewable Energy Laboratory (NREL) decade-long algae-to-fuel project was stopped by a decrease in oil prices in 1996, but currently there is a crisis starting to emerge, as oil deposits are located in countries not so democracy-friendly.

NREL is expected to start up again with algae within the next year. GreenFuel is a company developing systems that employ algae bioreactor technology to convert CO2 from smokestack flue gases to not pollutant, renewable biofuels, like biodiesel, ethanol or methane, while also decreasing toxic emissions.

This technology could be also a hit in limiting CO2 emissions while reusing it in renewable fuels, an economically and without retooling method. Experiments revealed a roughly 80 % CO2 capture rates during daylight hours.

LiveFuels is another company funding and coordinating research on algae-to-biocrude. “We could replace certainly all of our diesel fuel with algal-derived oils, and possibly replace a lot more than that”, said Kathe Andrews-Cramer, technical lead researcher for biofuels and bioenergy at DOE's Sandia National Laboratories.

Compression ignition engines and biodiesel

Biodiesel Expansion — Sat, 06 Sep 2008 23:30:55 +0000

To top it clear that the use of biodiesel in supplying engines with compression ignition is not a new concept of using vegetable oil as fuel being used since 1900 years. Then were conducted primary research on the consequences and the influences that these fuels can have on engines, but with the development and production of fuel abundance (because of the obvious advantages they present), fuel-based vegetable oils and Animal fats were ignored.

Contemporary problems that mankind has faced especially in the last two decades, linked environmental protection and duplication fuel price increases, have led to the rediscovery fuel-based vegetable oils (biofuels) that can be immediate answers to solve these problems. But in an interesting and specifically, the use of biofuels immediately taken before a study-related consequences and effects on internal combustion engines.
The use of biofuels immediate result and the ease of application of technological methods for obtaining them, the most “complex” issue is resolved to obtain a required minimum productivity of crops to plant oil rentabiliza economic use of biofuels and alternative (partial or total) Supplying internal combustion engines.
Developing future (and present) of theoretical and experimental studies on biofuels has shown that, in addition to validate the results already obtained beneficial about practice, there are negative effects (for example, emission of pollutants on the basis of nitrogen oxides – NOx) which require the need for thorough study of the experimental field of biofuels.
For faithful reproduction of all operational conditions of the engines fuelled by biofuels, attempts are made through stands trial on the basis of a rigorous methodology and a well-defined norms in force. Stands the test of engines fuelled by biofuels have the advantage of enabling the location of a large number of sensors that take the necessary information, analyzed using computer systems.
The main structure of a test stand is shown in Figure 1.

Fig.1. The structure of a stand of experimental tests engines. (1-diesel, 2-injection pump, 3-coupling pump training, 4-pump food; regulator 5-speeds, 6-lever Command cremalierei, 7-battery filters, 8-high-pressure pipeline; 9-injector, 10 back-fuel pipeline, 11-pipeline liquid cooling, 12-reservoir water hydraulic brake, transmission cardanică-13, 14-hydraulic brake, the 15-time interpreter, the interpreter 16-speed, 17-weight brake; 18.19-electrical connectors, 20-block with tanks feed mixed with rapeseed oil and diesel, 21-power reservoirs with mixtures of rapeseed oil, diesel tank-22, 23-food pipeline, 24-ramp to connection, 25-d food pipeline, 26-radiator, 27-purchasing system data)

It should be noted that the results obtained by testing experimental engine with a compression-ignition (diesel) are specific type of engine tried as a series of parameters constructivi and functional specific to each engine (cilindre, injection pressure, stroke injection, fuel flow injected, the type of injectors, type of room burns, etc.). have direct influence on the results obtained. It is recommended that for each type of engine (or at least an engine representative of a wide-functional tipodimensional) be made a specific programme of tests on the stand and operational practice.
However, tests carried out may provide an overview of opportunities for optimum use of power engines with compression ignition biodiesel. | n this vein below are the results of the experimental parameters functional to feed the engine type D-118 (used in the construction of agricultural tractors Romanian) with biofuel-based vegetable oils.
functional main parameters that have been taken into consideration are the consumption zone (CZ), specific fuel consumption (which), when engine (M) and actual power (by).

Fig.2 Changes in fuel consumption zone depending on the type of biodiesel used (vegetable oil rape)

Fig.3 Changes in specific fuel consumption depending on the type of biodiesel used (vegetable oil rape)

Fig.4 Change timing depending on engine type used biodiesel (vegetable oil from rapeseed)

Fig.5 Change effective power depending on the type of biodiesel used (vegetable oil rape)

For the experiments carried out on the same type of engine, but which has been used pure vegetable oil sunflower, functional change the parameters of engine compression ignition is shown in the figure 6.

Fig.6 Change functional parameters of engine D118 to feed sunflower oil (1-work mechanical indicated, 2-average power indicated; average 3-pressure indicated; yield 4-wise, 5-average effective pressure, 6-power effective, 7-effective yield, 8-specific consumption of fuel actually).

Based on the experimental results obtained for engine D 118 (engine common in wheeled agricultural equipment) and study variations of these data presented in the previous figures, we can say that:
– Fuel Classic (diesel) can be successfully replaced with mixed vegetable oil + gas oil (biodiesel) both through the prism of maintaining relative performance engine and the decrease in the price of fuel cost;
– In terms of consumption zone is observed that this increase with the decrease in the percentage of vegetable oil, the best results being obtained for B50 and B20 mixture + 5% methanol. | n similarly can say that for specific fuel consumption, it is more than the use of biodiesel, but in a very close range of approximately 10%;
– The best results on the timing for the engine to obtain the mix B20 + 5% methanol which are nearing the moment powered by diesel engine speed of over 1,600 rot / min respectively for mixed classical B10-B50 is found a decrease;
– The closer the actual values of engine power are obtained for a B10 biodiesel, and for the mixture of vegetable oil + diesel maximum studied finds an actual decrease in power with 10-12%;
– To feed an engine compression ignition fuel based on sunflower is found measured by the experimental results of the main indicators of functional engine (mechanical work and indicated actually indicated an average pressure and effective power indicated, the effective power, performance wise and actually, etc.). that they have lower values of 10-12% compared with the use of diesel as fuel. Specific consumption of fuel actually increased in this case with 28-30%;
– It is said that the use of fuel based on sunflower oil (pure or mixed) offers advantages of supplying engine compression ignition, but in this case should be stressed that it is necessary to achieve changes in the structure and system construction Petrol engine (injector, injection pump, filter system, etc.)..

Biodiesel – How to Make Biodiesel at Home

Biodiesel Expansion — Thu, 21 Aug 2008 14:08:26 +0000

Biodiesel, as an alternative fuel, boasts a number of benefits, but the biggest benefit is that anyone can make Biodiesel at home. Imagine being able to make your fuel for your vehicle or even power your entire home with the energy you created in your garage? That spells a lot of savings for you.

The process of making Biodiesel is not really that difficult. Making your own Biodiesel is a great idea if you can do it because you get to save more money in the long run when you use home-made Biodiesel.

Supplies to Making Biodiesel

To make a small batch of Biodiesel at home all you need are few supplies. You have to source out actual ingredients to make the Biodiesel alcohol, lye and vegetable oil. You also have to produce some supply requirements for mixing the fuel: empty plastic bottles, duct tape, a blender and measuring cups. Make sure that any inputs for the production of Biodiesel should not be used for any other purpose and never recycle such ingredients for cooking.

Once your supplies are in place, you can start learning the process of making Biodiesel

Hazard Free Procedure

Producing Biodiesel in not a risky business, health wise. Running the risk of inviting fire or explosion is minimal. In fact, the only major area of concern, as far as safety, hurting yourself due to flames. Exercise caution and ensure that the mixture’s temperature is under control.

You will undertake the simple procedure of Biodiesel production which entails blending the inputs, allowing it to settle, breaking up the byproduct and Biodiesel and then purifying the Biodiesel. The whole process can take a few days to a few weeks. That is dependent on the cleanliness level of your vegetable oil.

Low Volume or High Volume

The production of a Biodiesel can be in a small scale or a large scale basis. Using Biodiesel kits is way to go if a few gallons of diesel production is what your expect to achieve at a time. If you are running your lawnmower or other lawn equipment then A Biodiesel kit is ideal. It is practical to use and will not require a considerable level of supplies.

If you are after more production of Biodiesl like for fueling your automobile, you have to invest on a Biodiesel processor. This simplifies the process, so you can increase your level of production. With a processor you will need some more supplies but you also will not have to spend a lot of time making Biodiesel since the processor does most of the work for you.

BIODIESEL FUELS 101

Biodiesel Expansion — Sat, 24 May 2008 08:41:37 +0000

People have always heard biodiesel fuels and all that in school and form other fellow truck drivers but few really understand its essence and component. Biodiesel fuel is a kind of diesel that is not made of petroleum. This means that this has natural compounds such as fats and oils. That is why it is also called fatty acid methyl or FAME.

The creation or development of this oil is credited to G. Chavanne in 1937. He was granted a patent for creating a process of transforming vegetable oil into a fuel. This process is known as alcoholysis—a process known today as transesterification. This is called so because biodiesel fuels l is a mono-alcoholic mixture. Vegetable oil and fatty acids are mixed with ethanol, to be specific.

Ideally, the mixture should of biodiesel fuels be made of the vegetable oil and glycerol. Glycerol is also known to many people as glycerine. This is a chemical compound that is made of lipids. It is non-toxic and it is odorless. However, it was preferred by many that ethyl is used instead of glycerol because glycerol is a sugar based alcohol.

Biodiesel is measured in terms of the B Factor. This letter “B” mean blend. If a biodiesel fuels blend is 15%, then the blend is known as B15. If it is 20%, then the biodiesel blend is called B20. This is not ideally used 100% because it will cause complications in the vehicles. This is because biodiesel burns fast. And as such, there is a need to replace filters often.

Biodiesel Expansion – Is it a Right Time for Alternative Fuels?

Biodiesel Expansion — Thu, 15 May 2008 04:54:45 +0000

Irreversible Fossil Oil Price now goes up like a rocket. The price of the fossil oil really unpredictable and looks like “Unstoppable”. So, is it the right time for alternative energy for our car fuels? Do you ever heard a word of “Biodiesel Expansion”? Yes, this word is really popular nowadays beside HHO Gas Cars, because many people really hungry with an alternative fuels for their cars.

What is Biodiesel?And What is Biodiesel Expansion?
Biodiesel is one alternative of energy fuel which come from renewable sources such as vegetable oil or “Jarak Oil”. In the Biodiesel fuel consist of short chain alkyl esters and called mono alkyl esters in science term. Biodiesel expansion is an expansion of many industries to change their fuels from petroleum fuel to non petroleum based diesel fuel.

Beside of the highly priced of the petroleum oil nowadays, People and industries decide to expand their fuels from petroleum to Biodiesel fuel because of the Global warming issue. Now, many people concern with more eco friendly fuels, so they decide to use alternative fuel from renewable sources like biodiesel fuel.

This is a sample of Biodiesel Fuel:
