20080312348 - Method and apparatus for steam hydro-gasification with increased conversion times: A method and apparatus for converting carbonaceous material to a stream of carbon rich gas, comprising heating a slurry feed containing the carbonaceous material in a hydrogasification process using hydrogen and steam, at a temperature and pressure sufficient to generate a methane and carbon monoxide rich stream in which the... Agent: Robert Berliner Berliner & Associates

20080312347 - Production of hydrocarbons from natural gas: A process for producing hydrocarbons from natural gas includes, in a cryogenic separation stage, cryogenically separating the natural gas to produce at least a methane stream and natural gas liquids, in a reforming stage, reforming the methane stream to produce a synthesis gas which includes at least CO and H2,... Agent: Alston & Bird LLP

20080306171 - Method to start a process for producing hydrocarbons from synthesis gas: Method to start a steady state process for producing normally gaseous, normally liquid and optionally normally solid hydrocarbons from synthesis gas, which process comprises the steps of: (i) providing the synthesis gas; (ii) catalytically converting the synthesis gas in one or more conversion reactors at an elevated temperature and a... Agent: Shell Oil Company

20080306172 - Method of preparing catalyst support from a waste catalyst: A method of preparing, preferably recycling, a catalyst support material is disclosed and is particularly applicable to recycling a titania support. The invention includes crushing the used catalyst support that is obtained by leaching catalytic components from a used supported catalyst and preferably combining it with new catalyst support in... Agent: Shell Oil Company

20080306173 - Process for preparing a hydrocarbon synthesis catalyst: A process for the preparation of a catalyst or catalyst precursor, comprising the steps of: (a) admixing: (i) a catalytically active metal or metal compound (ii) a carrier material (iii) a gluing agent; and (iv) optionally one or more promoters, and/or one or more co-catalysts; (b) forming the mixture of... Agent: Shell Oil Company

20080300326 - Processing residue gas of a fischer-tropsch process: The invention concerns a method for converting hydrocarbon-containing gases into hydrocarbon-containing liquids wherein the Fischer-Tropsch process is implemented, said Fischer-Tropsch process producing hydrocarbon-containing liquids and a residue gas comprising at least hydrogen, carbon monoxide, carbon dioxide and hydrocarbons having a carbon number not more than 6, wherein the residue gas... Agent: Air Liquide Intellectual Property

20080300327 - Process for producing liquefied petroleum gas: A synthesis gas is produced from a carbon-containing starting material such as a coal; a CO-containing gas is separated from the resultant synthesis gas, whereby obtaining a gas containing carbon monoxide and hydrogen; a methanol- and/or dimethyl ether-containing gas is produced from the resultant gas containing carbon monoxide and hydrogen;...
