(Fuel) Despite a crop of cane sugar mostly ALCOHOL, Brazilian exports of ethanol should end the year in negative compared to 2012. In the evaluation of experts and industry representatives, weakening demand from the United States should reverse the remainder of the second half, an increase of almost 50% growth in the year to July. That's because Americans have preferred to biodiesel instead of ethanol from sugar cane as a way to fill the quota of advanced biofuels, stipulated by the Renewable Fuel Standard (RFS) program of renewable fuels in the country. Biodiesel is…

Ultrasound accelerates the catalytic transesterification of vegetable oils and animal fats into biodiesel. This allows the change of the classical batch production to continuous production. Such a change reduces the investment costs and increased profitability. Biodiesel is mainly produced in a batch process. Heat and mechanical agitation cause the process to energy and support the transesterification. The mixing by ultrasonic cavitation is an effective alternative for industrial transesterification of oils and fats into biodiesel. Transesterification (Chemical conve…

Display No country produces as much ethanol as the U.S.. Ex-President Bush had decided to quintuple the amount of biofuel. Especially the corn state of Iowa benefits from E15 at the pump. While in Germany nor E10 is discussed in the U.S. is already a new fuel type on the market: E15. Since January this year, the Environmental Protection Agency has released the mixture with fifteen percent ethanol - for vehicles that were produced between 2001 and 2006. Click to enlarge By 2022, the production of biofuels in the U.S. to be fivefold compared to 2007. The officials are …

Municipal solid waste from the requirements of ASTM D6866 biofuel test part of this renewable fuel can not be based on renewable biomass and fossil raw materials to determine the relative energy content Want to determine biological renewable fuels blended fuel exporters can use the content of ASTM D6866 Beta Labs to provide transportation fuels ASTM D6866 testing. The company did not join the United States Environmental Protection Agency or renewable fuels standard planning Some renewable fuels ASTM D6866 test U.S. EPA allows biofuel producers using municipal solid w…

Content Print this page Liquid biofuels Sunflower © Rainer Weisflog Meanwhile, the first-generation biofuels, ie, vegetable oil, biodiesel (PME) and bioethanol, very well known. In particular, biodiesel is firmly established on the German market, since this alternative fuel to 31 July 2006 no fuel tax was levied. In addition, a blend of 5 percent biodiesel with fossil diesel is required. 5 percent bioethanol in gasoline allowed by the standard. In the E10 fuels even a ten percent addition of bioethanol to gasoline is available. In the latter, the pure biodiesel fuels…

The production and the optimization of the growth of yeast on crude glycerol from biodiesel Screening in the subject in this work was conducted with the purpose of verifying whether the crude glycerol, a by-product of the processing of biodiesel, can be used as carbon source for the production of biomass. Of the 113 yeast strains tested, 45 have grown in pure glycerol with growth rates ranging 0.11 to 0.37 h-1. Twenty-three strains showed specific growth rates (h-1), the production of biomass and biomass yields higher or comparable to those obtained after growth on p…
