The biosynthetic oil can contain all levels of common commercial vegetable and animal fats in any ratio. The hybrid fuel also contains up to about 0.17% stabilizer, which further contains cetane boosters, cleaning agents to remove deposits from the fuel system, a lubricant, demulsifiers, and anti-gelling agents. The invention functions as biocide to inhibit bacterial growth. The invention is substantially equivalent to Diesel Number 2 in terms of power and engine speed, but is cleaner burning and considerably less costly.Type: ApplicationFiled: December 10, 2009Publication date: April 8, 2010Applicant: Tellus Renewables LLCInventor: Timothy Dion Wetzel

Publication number: 20100064573Abstract: The present invention discloses a method for producing a liquid fuel or at least one of its primary components from carbonaceous material, wherein a concatenation of individual processes, which make up the entire method, are employed. The concatenation of processes employed in said novel method has the potential to provide an exothermic operation during the production of the liquid fuel, or the at least one primary component, thereby producing a portion of its own raw material, supplying the majority of its energy requirements and consuming the majority of its byproducts, which in turn reduces feedstock reactant requirements for said method.Type: ApplicationFiled: September 15, 2008Publication date: March 18, 2010Inventors: Mario Araya Brenes, Luis Diego Ramirez Mendez

Publication number: 20100050502Abstract: The invention provides a system for obtaining biofuel from an algae composition comprising algae and water. The system comprises a pump for pressurizing the algae composition to a predefined pressure and a heater for heating the algae composition to a predefined temperature. Lipids in the algae are extracted and/or hydrolyzed to form fatty acids at a set of predefined temperature and pressure. The water may be in a subcritical or supercritical state at the predefined pressure and predefined temperature. The system further comprises a separator for partitioning the treated algae composition into an organic phase which includes the lipids and/or fatty acids, an aqueous phase, and a solid phase with biomass residue, and for collecting the organic phase. The organic phase can be upgraded to biofuel.Type: ApplicationFiled: August 20, 2009Publication date: March 4, 2010Applicant: LiveFuels, Inc.Inventors: Benjamin Chiau-pin Wu, Charity Ann DeLuca, Emma Kathryn Payne

Publication number: 20100043280Abstract: A method of producing biodiesel from a source of triglycerides. The source of triglycerides is reacted with a blended alcohol composition in the presence of a catalyst to form a mixture of at least one fatty acid alcohol ester and glycerin. The fatty acid alcohol ester is then separated from the glycerin and is purified to produce a biofuel. The blended alcohol composition comprises at least one lower alcohol, a ketone and ethyl acetate. The use of the blended alcohol composition allows the transesterification process to proceed under ambient temperature and pressure conditions within a relatively short reaction time.Type: ApplicationFiled: November 21, 2008Publication date: February 25, 2010Inventor: Martin Allan Morris

Publication number: 20100043279Abstract: A process for hydrocracking biomass, and the hydrocarbons produced therefrom. A feed stream having free fatty acids, fatty acid esters, or combinations thereof is contacted with a first catalyst under hydrogen pressure and heat. The hydrocarbon product stream which is comprised predominantly of n-paraffins is separated into heavy and light fractions. The heavy fraction is contacted with a second catalyst under hydrogen pressure and heat to produce an effluent stream which is combined with the light n-paraffin fraction to form a unique middle distillate product useful as a diesel or jet fuel.Type: ApplicationFiled: August 21, 2008Publication date: February 25, 2010Inventors: Ramin Abhari, Lynn Tomlinson, Peter Havlid, Nathan Jannasch
