20150191657 | DIRECT COAL LIQUEFACTION PROCESS - A direct coal liquefaction method and apparatus in which the feed coal is mixed with a recycled 600° F.+ non-donor stream in which the ratio of coal to said stream is at least 1.5:1 on a moisture free basis to form an input slurry to a DCL reactor. Hydrogen containing treat gas is supplied to the reactor. 1000° F.− bottoms from the reactor are recycled as part of the 600° F.+ non-donor stream. 1000° F.+ bottoms from the reactor are gasified in a PDX unit to provide hydrogen for the DCL reaction. The ratio of recycled bottoms to feed coal is between 1:0.5 and 1:1.5. | 07-09-2015 |
20140345341 | INTEGRATED PROCESSES FOR PRODUCING FUELS AND BIOFERTILIZERS FROM BIOMASS AND PRODUCTS PRODUCED - An IBTL system having a low GHG footprint for converting biomass to liquid fuels in which a biomass feed is converted to liquids by direct liquefaction and the liquids are upgraded to produce premium fuels. Biomass residues from the direct liquefaction, and optionally additional biomass is pyrolyzed to produce structured biochar, hydrogen for the liquefaction and upgrading, and CO | 11-27-2014 |
20140296595 | Methods And Apparatus For Producing Aromatics From Coal - A method for converting coal into BTX in which feed coal is converted to a 600-700° F.− product stream by direct liquefaction. This product stream is hydrocracked and hydroprocessed to produce a 350° F.− stream which in turn is fractionated to produce a 160° F.− stream and a 160/350° F. stream that contains 85-90% naphthenes. The 160/350° F. stream is catalytically reformed to produce an aromatic stream and a 160° F.− paraffinic stream. The aromatics stream can be separated into benzene toluene and xylene streams by distillation. | 10-02-2014 |
20140262965 | Liquid Fuel Production Process and Apparatus Employing Direct and Indirect Coal Liquefaction - A method and apparatus for producing liquids from coal including diesel and jet fuel blends and BTX in which the coal feed is converted to liquids in a DCL reactor, the produced liquids are upgraded and separated into, naphtha and DCL jet or diesel blend stock streams, the C3/180-350° F. stream is converted in a Fischer Tropsch reactor to produce a highly paraffinic diesel or jet fuel blend stock and the DCL and Fischer Tropsch blend stocks are blended in controlled ratios to produce premium diesel or jet fuels meeting applicable specifications. | 09-18-2014 |

20120144887 | Integrated Coal To Liquids Process And System With Co2 Mitigation Using Algal Biomass - An ICBTL system having a low GHG footprint for converting coal or coal and biomass to liquid fuels in which a carbon-based feed is converted to liquids by direct liquefaction and optionally by indirect liquefaction and the liquids are upgraded to produce premium fuels.

20110263914 | Synthetic Fluids and Methods of Manufacture - A method for producing synthetic fluids from TGFA's harvested from genetically modified seed crops in which all of the fatty acids in the TGFA's from the seeds of a crop have the same carbon atom chain length, preferably C12 or C14, and the synthetic fluids produced by the method. The TGFA's are hydroprocessed to cleave the fatty acids from the glycol backbone and to hydrodeoxygenate and isomerize the fatty acids to form single carbon chain length isoparaffins having a controlled degree of branching with minimum cracking. Controlled mixtures of hydrocarbon components, in which each hydrocarbon component of the mixture has a different single carbon atom chain length, are produced. The relative ratios of the single carbon atom number hydrocarbons in the mixture are selected to optimize the characteristics of the synthetic fluid product for a given application, if the end product is an SDF, the severity of the hydrotreatment is controlled such that the degree of cracking is minimized and the isomers generated are primarily monomethyl isoparaffins. If the end product is a jet fuel blend stock, the hydrotreatment is somewhat more severe in order to generate multiple branched isomers that have improved aerobic biodegradability and low temperature properties. The degree of hydrotreatment is controlled to limit the degree of branching in order to preserve the required thermal and oxidative stability properties, and to minimize cracking. | 10-27-2011 |
20090286889 | INTEGRATED COAL TO LIQUIDS PROCESS AND SYSTEM - An integrated coal-to-liquids process is provided to minimize carbon dioxide emissions and efficiently make use of carbon resources, by recovering carbon dioxide emissions from Coal-to-Liquids (CTL) facilities, using the recovered carbon dioxide in at least one carbonylation reaction step for converting ammonia to urea and then converting urea into dimethyl carbonate. | 11-19-2009 |
