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
If you have tried for months to earn money online, then you will probably feel frustrated and want to leave everything behind. Is that you? If so I ask you not give up. The Internet has made many people rich and you can do the same if I attached to it. The key is finding a work system and work with that system.

If you really want to make money online, enough to replace your current job, then you have every possible effort.
Roshydromet drafted climate doctrine, and the Ministry of Energy proposes to create a market for the sale of carbon credits. Rostekhnadzor called the most favorable and unfavorable environmental terms of the Krasnodar Territory. Winter in Russia will be reduced by almost a month. In Russia there will be domestic analogue TV channels Discovery and National Geographic. Climate change on Earth is much faster than predicted.
Researchers found that the same animals live at both poles of the Earth. Tropical forests are absorbing more carbon dioxide. Swan – a bird in 2009. Whale Week: World Day of whales and Photo-fact ‘in the world of whales. ” —- A short review of the major environmental news for the week. —- The chemical method of producing biofuel U.S. researchers have developed the first single-stage synthesis of the precursor of biofuels unprocessed agricultural residues. The results of the work will lead to the development of a simple and effective way to produce biofuel. Biochemist Ron Rains (Ron Raines) from the University of Wisconsin-Madison received directly 5 gidroksimetilfurfural 5-hydroxymethyl-fufural (HMF) of raw corn straw. The resulting compound can be used as feedstock for the synthesis of many substances, including the potential as a biofuel dimetilfuran dimethylfuran (DMF). —- Off the coast of Ireland recorded spills of up to 300 tons of oil in 120 miles south of the Irish port of Cork in the Atlantic got about 300 tons of fuel oil. According to the Ministry of Transport Ireland, a fuel leak, presumably, could occur during refueling ships of the Navy of Russia, who are currently in the area. The representative of the Irish Ministry of Transport special noted that in this case we are not talking about the accident or collision of ships. —- Medvedev: Baykal should be clean and comfortable for the rest one of the world’s largest freshwater lake – Baikal – must be clean and at the same time have a developed tourist infrastructure, said Russian President Dmitry Medvedev at a meeting with the governor of Irkutsk Region Igor Yesipovsky. —- Two solar and lunar eclipses occur four to During the International Astronomical Year – 2009 Rich in rare astronomical phenomena will be this year. At today’s press secretary main / Pulkovo / Astronomical Observatory RAS Sergey Smirnov by press conference at the regional center of ITAR-TASS news agency, until the end of this year there will be six eclipses – two solar and lunar four. Of the four lunar eclipses three – February 9, July 7 and August 5-6 – are the half-shadow, he said. In his said, ‘in Russia will observe the solar eclipse July 22 and the shadow lunar eclipse on December 31. In the southern regions of Siberia and the Far East can be observed partial solar eclipse on July 21-22 “, – noted Pulkovo astronomer. —- Tea bags is hazardous to health researchers from the Medical College at Washington University in St. Louis (USA) found that in packaged tea contains dangerously high quantities of fluoride.
Weak targets from America and Asia allow stock markets and crude oil prices sink LEIPZIG. (Ceto) Crude oil prices were now barely moves. Missing economic stimulus, fears of a U.S. recession as well as a continued over supply market situation led to caution investors. Heating oil consumers in Germany could look forward, however, for the first time since three days of falling prices.
The U.S. economy does not get out of the headlines. On the horizon of the world’s biggest consumer the first recession clouds slowly. One of the messages, which today startled investors: the Department of energy (DOE) lowered its forecast for daily oil demand. It is 48,000 barrels per day lower now 19,291 barrels.
This is more than during the crisis years 2009 and 2009, but still far below the required quantities previously, as the daily consumption was more than 20 million barrels. This was accompanied by growing stocks go. Analysts expect that the American Petroleum Institute (API) today a further inventory build-up to 1.3 million barrels reported for the past week. That would be the highest value since weekly records began in 1990. “” Even the hurricanes seem to spare the conveyor systems in the Gulf of Mexico, according to Earl”now Danielle”and Fiona”, so in any case, an assessment of the National Hurricane Center. This would encourage a further inventory build-up and thus cement over supply situation on the market. Due to this development, the crude oil prices showed today barely moves and lost in the afternoon easily compared to yesterday’s day finally. German heating oil consumer this brought the first price reductions to the end of the month for three days with. 100 litres in a total quantity of 3,000 litres heating oil EL paid for today the national average with 67,16 euro 19 cents to less than yesterday. In the monthly average August, crude oil cost 66,86 euro. For comparison: In August 2009, the same amount cost average 57,52 EUR. in 2008, there were exactly 87,00 euro. It reported the online portal of the fuel level magazine and petroleum review. The graphics on the energy Portal show the development of the domestic fuel oil prices in the national average, and in the individual federal States in the section of market data. Regional deviations are possible due to the market at any time.
