Scientists and biofuels experts said biofuels could be developed to operate on conventional diesel engines, which would help to expand the use of renewable fuels as new biodiesel, which has been manufactured through a number of plant materials, To provide a more environmentally friendly alternative to fossil fuels, which is now heavily used as a premium to petro-diesel. It is worth mentioning that the EU requires commercial diesel to contain at least 7% of biodiesel.
The possibility of normal diesel engines working on biodiesel: - The micro-structure of these types of biofuels is originally indicated to boil at temperatures different from those of the thermocouple, which means that the engines designed for normal diesel will be able to operate On pure biodiesel or other mixtures thereof, which in their composition contain a large proportion of biofuels.
This is confirmed by a group of German scientists and specialists who have found a way to convert plant-derived chemicals into bio-diesel fuel to meet the boiling characteristics required by the EN590 standard developed by the European Commission for Standardization of Commercial Diesel sold in the market .
How did the idea start? - The idea was first conceived when Lucas Guin, a professor of organic chemistry at Ruhr Universitat Bochum, who led the research, confirmed that his motives for research came during a trip to a biodiesel plant in Rwanda years ago. The problem was that only one bus had been diverted to run the fuel, due to the lack of required financial supplies.
Why biodiesel does not work on standard diesel engines: - The main reason why biodiesel does not work on standard diesel engines is that 95% of its constituent particles are of the same length, so they boil at about the same temperature, and In contrast to petrodiesel, which is made up of a mixture of hydrocarbons of different lengths, it boils at different temperatures and gives the fuel a wider range of boiling.
More importantly, modern cars have already been designed on the basis of these characteristics, although there are several existing processes that can convert vegetable oils into biofuels suitable for use in standard engines (diesel engines) but a large proportion of fuel is burned to carry out a process This is why Begwin and his colleagues are looking for a way or a possibility to take advantage of these catalysts, which accelerate the process of chemical reaction.
For their part, they used a mixture of three catalysts to be able to mix raisin ester, methyl oil (RM), a common feedstock for biofuels, and ethylene to fuel with the same personal boiling point as Petrodiesel, ethylene , hydrocarbons, Which was generated through ethanol originally extracted from plants or rock gas.
Highlighted the experiments carried out by scientists in this field in order to prove that biofuels fit fuel for cars: - The scientists built a diesel car model, and used fuel bio-diesel in the propulsion process, but the result came that biofuels is still far - fetched process Marketing to date, due to its large financial cost as the financial cost of its first payment amounted to more than $ 1125 per quarter liter produced.
Challenges and Obstacles to the Use of Biofuels: - The biggest challenges or obstacles facing his project are that it is not suitable for standard diesel engines, despite the vision of researchers, which believes that this problem can be overcome by the bonus to the need to solve the problem point Boiling, which to be eliminated will have to face tougher challenges.
And how to find a cheaper incentive to do so as well as how to convert biodiesel to be suitable for motor vehicles, although scientists need to find new types of renewable fuels to rely on as a substitute for fossil fuels currently used.
