20080027150 - Hydrocarbons synthesis: A process for synthesising hydrocarbons includes feeding a gaseous feedstock comprising hydrogen, carbon monoxide and carbon dioxide, into a dimethyl ether (DME) synthesis stage, and in the DME synthesis stage, converting a portion of the gaseous feedstock into a DME product and gaseous products. The DME product is separated from... Agent: Ladas & Parry

20080021118 - Hydrocarbon recovery in the fischer-tropsch process: The invention provides an improved hydrocarbon recovery process of the Fischer-Tropsch process overhead stream using a scrubber system. Described is a process for recovering Fischer-Tropsch hydrocarbons from a reactor exit gas produced from a Fischer-Tropsch synthesis operation. The process includes (a) passing the reactor exit gas to a gas/liquid contactor;... Agent: Baker & Mckenzie LLP

20080021120 - Operation of a steam hydro-gasifier in a fluidized bed reactor: Carbonaceous material, which can comprise municipal waste, biomass, wood, coal, or a natural or synthetic polymer, is converted to a stream of methane and carbon monoxide rich gas by heating the carbonaceous material in a fluidized bed reactor using hydrogen, as fluidizing medium, and using steam, under reducing conditions at... Agent: Robert Berliner Berliner & Associates

20080021119 - Operation of a steam methane reformer by direct feeding of steam rich producer gas from steam hydro-gasification: An improved, economical alternative method to supply steam and methane to a steam methane reformer (SMR) is accomplished by a combination of procedures, wherein product gas from a steam hydro-gasification reactor (SHR) is used as the feedstock for the SMR by removing impurities from the product stream from the SHR... Agent: Robert Berliner Berliner & Associates

20080021123 - Method and apparatus for steam hydro-gasification in a fluidized bed reactor: A method and apparatus for converting carbonaceous material to a stream of methane and carbon monoxide rich gas by heating the carbonaceous material in a fluidized bed reactor using hydrogen, as fluidizing medium, and using steam, under reducing conditions at a temperature and pressure sufficient to generate a stream of...

Agent: Robert Berliner Berliner & Associates

20080021121 - Controlling the synthesis gas composition of a steam methane reformer: A method for controlling the synthesis gas composition obtained from a steam methane reformer (SMR) that obtains its feedstock as product gas directly from a steam hydro-gasification reactor SHR). The method allows control of the H2/CO syngas ratio by adjusting the hydrogen feed and the water content of feedstock into... Agent: Robert Berliner Berliner & Associates

20080015267 - Fischer-tropsch catalysts incorporating promoter for increasing yields of c5+ hydrocarbons and methods for making and using same: An improved skeletal iron catalyst is provided for use in Fischer-Tropsch synthesis reactions for converting CO and H2 to hydrocarbon products. The skeletal iron catalyst is manufactured using iron and a removable non-ferrous component such as aluminum. The iron and removable non-ferrous component are mixed together to form a precursor... Agent: Workman Nydegger

20080015266 - Method for activating an iron-based fischer-tropsch catalyst: A method for transforming at least a part of the catalyst precursor hematite into χ-carbide (Fe5C2) and ε′-carbide (FeC2.2) without a large amount of fines generation. This method slows the transformation of the hematite to iron carbides by reducing the partial pressure of the synthesis gas by inert gas dilution.... Agent: Conley Rose, P.C. David A. Rose

20080009553 - Titania supports and catalysts: A process for the preparation of a titania catalyst or a titania catalyst carrier is described. It comprises the steps of: obtaining a wet filtercake of titania, the titania having been made by hydrolysis of a suitable titanium compound, optionally admixing the wet filtercake with one or more catalyst materials,...
