Biodiesel Bioethanol

History and differences from fossil fuels to biofuels are a hot topic. But the development of these fuels, which slowly to substitute fossil fuels to low, isn’t so new, as it is believed. Proceedings were almost 50 years before the invention of the diesel engine developed for the production of bio-diesel for example already in the middle of the 19th century. Just like today the former mixture based on the basis of vegetable oils, during this time gained from peanuts. Around the turn of the century then, even Rudolf diesel was highly personally on this new fuel carefully and showed at the Paris world exhibition 1900 surprised that normal diesel engines without modification with the vegetal fuel ran. Another important step was followed in 1937, when the Belgians G. Chavarine patented a process of Transesterification with ethanol and methanol. Thus significantly improved the conditions for the use of bio-fuels as a fuel substitute.

Even a bus line was converted at that time with this procedure. In the following Decades improved considerably, the production of biofuels has been standardized the process for the production of biodiesel fuel quality until 1983. Austria then in 1989 inaugurated a plant for the commercial production of bio-fuel that could produce 30000 tons in the year. Many more followed in the 1990s. Meanwhile, many countries, including also Germany and the United States, compulsory blending of biodiesel have introduced to conventional diesel, to protect the environment and reduce carbon dioxide emissions. The biggest difference between classic oil and vegetable oil, based on the bio-fuels, is the origin of course.

While oil from underground, huge oil reserves funded for example on offshore oil rigs or oil, vegetable oil is obtained from renewable raw materials such as sugar cane or oilseed rape. Both methods have advantages and disadvantages. The technology for the promotion of mineral oil is mature and it is possible to use large quantities of oil to promote. However, oil reserves are limited and will go in the future to the tilt. In addition, only a few countries have access to oil resources, which leads to high prices and political tensions. But also the production of vegetable oil has its disadvantages. While the raw materials are renewable, whose production in the competition for the production of food is available. Often the use of arable land for the production of biofuels in developing countries could lead to disruptions in the food production and supply. A trend from which to fear is that he will still grow in the future. Christian Jung
