Publication number: 20110296742Abstract: A process for obtaining a combustible or fuel, respectively, by thermally cracking a heavy oil in the presence of a wet, hydrocarbonaceous biomass by heating the heavy oil until the pyrolysis of the hydrocarbonaceous biomass, whereby the combustibles and fuels, respectively, are formed, removed from the heated heavy oil and subsequently condensed, characterized in that a hydrocarbonaceous biomass is used the moisture content of which amounts to, at most, 1.0% by weight, based on the biomass.Type: ApplicationFiled: September 17, 2009Publication date: December 8, 2011Applicant: BDI-BIOENERGY INTERNATIONAL AGInventors: Helmut Goessler, Wilhelm Hammer

Publication number: 20110296743Abstract: The present invention relates to a fuel composition comprising at least one biodiesel fuel and comprising 0.05 to 5% by weight of at least one polymer comprising ester groups, which comprises repeat units derived from ester monomers having 16 to 40 carbon atoms in the alcohol radical, and repeat units derived from ester monomers having 7 to 15 carbon atoms in the alcohol radical, and the polymer comprising ester groups has a weight-average molecular weight in the range from 5000 to 100 000 g/mol. The present invention further describes the use of polymers comprising ester groups as flow improvers in fuel compositions which comprise at least one biodiesel fuel. Surprising advantages can be achieved especially with regard to the improvement of the cloud point and the low-temperature storability.Type: ApplicationFiled: December 29, 2009Publication date: December 8, 2011Applicant: EVONIK ROHMAX ADDITIVES GMBHInventors: Rene Koschabek, Yann D'Herve, Phil Hutchinson, Brian Hess, Sandra Kuenzel

Publication number: 20110289827Abstract: A process of solubilizing organic solids that includes reacting an organic solid with an oxidant in superheated water to form a solubilized organic solute. Preferably, the organic solid is selected from the group consisting of coal, lignite, kerogen, biomass, solid organic wastes, and mixtures thereof. The oxidant preferably is molecular oxygen.Type: ApplicationFiled: February 11, 2010Publication date: December 1, 2011Applicant: SOUTHERN ILLINOIS UNIVERSITY CARBONDALEInventors: Kenneth B. Anderson, John C. Crelling, William W. Huggett

Publication number: 20110289826Abstract: A process for producing fuel by cracking vegetable oil in a pure state or mixed with a residual hydrocarbon oil, which is obtained from a pyrolysis process, using a dolomite catalyst. The residual hydrocarbon is produced by the pyrolysis of plastic waste, such as of one or more of polyethylene, polystyrene or polypropylene. The mixture of vegetable oil and the residual hydrocarbon oil is first subjected to a semi-batch catalytic cracking reaction over a very low cost dolomite catalyst to obtain high quality oil for fuel, which comprises mainly light and heavy naphtha. Moreover, the catalytic cracking reaction is conducted at operating temperatures lower than 450° C.Type: ApplicationFiled: May 27, 2010Publication date: December 1, 2011Inventor: Jumluck Srinakruang
