Patent number: 9371495Abstract: A method for producing naphthenic process oils that have a high content of naphthenic carbon atoms of 20-60 wt % and a low content of polycyclic aromatics of less than 3 wt %, determined in accordance with IP 346, by the hydrogenation of a process oil educt that has a high content of polycyclic aromatics, are provided. The method enables secondary extracts, such as are formed in the production of label-free process oils, even in a mixture with primary extracts, to be utilized in an economically meaningful way. The resulting process oils are likewise label-free, so that the use of PCA-containing process oils can be reduced and less of these substances will get into the environment. By avoiding heating oil, CO2 emissions are also reduced. Also, through the direct hydrogenation of DAE, high value naphthenic process oils are obtained. The process oils that are obtained contain surprisingly high amounts of naphthenic hydrocarbon compounds.Type: GrantFiled: October 14, 2010Date of Patent: June 21, 2016Assignee: Klaus Dahleke KGInventor: Nils Hansen

Patent number: 8152870Abstract: A method for producing biofuels is provided. A method of making biofuels includes dewatering substantially intact algal cells to make an algal biomass, sequentially adding solvent sets to the algal biomass, and sequentially separating solid biomass fractions from liquid fractions to arrive at a liquid fraction comprising neutral lipids. The method also includes esterifying the neutral lipids, separating a water miscible fraction comprising glycerin from a water immiscible fraction comprising fuel esters, carotenoids, and omega-3 fatty acids. The method also includes obtaining a C16 or shorter fuel esters fraction, a C16 or longer fuel ester fraction, and a residue comprising carotenoids and omega-3 fatty acids. The method includes hydrogenating and deoxygenating at least one of (i) the C16 or shorter fuel esters to obtain a jet fuel blend stock and (ii) the C16 or longer fuel esters to obtain a diesel blend stock.Type: GrantFiled: April 6, 2011Date of Patent: April 10, 2012Assignee: Heliae Development, LLCInventor: Aniket Kale

Patent number: 8063258Abstract: A process for producing fuel from biomass is disclosed herein. The process includes torrefying biomass material at a temperature between 80° C. and 300° C. to form particulated biomass having a mean average particle size from about 1 ?m to about 1000 ?m. The particulated biomass is mixed with a liquid to form a suspension, wherein the liquid comprises bio-oil, wherein the suspension includes between 1 weight percent to 40 weight percent particulated biomass. The suspension is fed into a hydropyrolysis reactor; and at least a portion of the particulated biomass of the suspension is converted into fuel.Type: GrantFiled: November 2, 2010Date of Patent: November 22, 2011Assignee: Kior Inc.Inventors: Robert Bartek, Michael Brady, Dennis Stamires

Patent number: 8038869Abstract: Processes and systems are provided for removing contaminants from a vapor stream containing hydrocarbon and hydrogen, and can include: providing a feed stream to a first pressurized vapor liquid separator that produces a liquid stream and a vapor stream containing hydrocarbon and hydrogen, passing the vapor stream to an inlet of a particulate trap containing a plurality of treatment zones that remove contaminants from the vapor stream to produce a particulate trap effluent, and passing the particulate trap effluent directly to a catalytic hydrogenation zone. The processes and systems can also include: passing the liquid stream from the first pressurized vapor liquid separator to a second vapor liquid separator that produces an overhead vapor stream and a liquid bottoms stream, condensing the overhead vapor stream from the second vapor liquid separator to form a liquid overhead stream, routing the liquid overhead stream to the inlet of the particulate trap.Type: GrantFiled: June 30, 2008Date of Patent: October 18, 2011Assignee: UOP LLCInventor: Tom N.
