Patent application numberDescriptionPublished
20100160464Zeolite Supported Cobalt Hybrid Fischer-Tropsch Catalyst - A method for forming a catalyst for synthesis gas conversion comprises impregnating a zeolite extrudate using a solution, for example, a substantially non-aqueous solution, comprising a cobalt salt to provide an impregnated zeolite extrudate and activating the impregnated zeolite extrudate by a reduction-oxidation-reduction cycle.06-24-2010
20100312030PROCESS OF SYNTHESIS GAS CONVERSION TO LIQUID FUELS USING SYNTHESIS GAS CONVERSION CATALYST AND NOBLE METAL-PROMOTED ACIDIC ZEOLITE HYDROCRACKING-HYDROISOMERIZATION CATALYST - A process is disclosed for converting a feed comprising synthesis gas to liquid hydrocarbons within a single reactor at essentially common reaction conditions. The synthesis gas contacts a first catalyst bed comprising a synthesis gas conversion catalyst, and a second catalyst bed comprising a mixture of a hydrogenation catalyst and a solid acid catalyst. A Fischer-Tropsch wax is formed over the first catalyst bed and the wax is then hydrocracked and hydroisomerized over the second catalyst bed, resulting in liquid hydrocarbons substantially free of solid wax.12-09-2010
20110118368PROCESS OF SYNTHESIS GAS CONVERSION TO LIQUID FUELS USING MIXTURE OF SYNTHESIS GAS CONVERSION CATALYST AND DUAL FUNCTIONALITY CATALYST - A process is disclosed for converting a feed comprising synthesis gas to liquid hydrocarbons within a single reactor at essentially common reaction conditions. The synthesis gas contacts a catalyst bed comprising a mixture of a synthesis gas conversion catalyst on a support containing an acidic component and a dual functionality catalyst including a hydrogenation component and a solid acid component. The hydrocarbons produced are liquid at about 0° C., contain at least 25% by volume C05-19-2011
20110124750ZEOLITE SUPPORTED COBALT HYBRID FISCHER-TROPSCH CATALYST - A method for performing synthesis gas conversion is disclosed which comprises contacting synthesis gas with a hybrid Fischer-Tropsch catalyst formed by impregnating a ZSM-12 zeolite extrudate using a solution, for example, a substantially non-aqueous solution, comprising a cobalt salt and activating the impregnated zeolite extrudate by a reduction-oxidation-reduction cycle. The method results in reduced methane yield and increased yield of liquid hydrocarbons substantially free of solid wax.05-26-2011
20110144219ZEOLITE SUPPORTED COBALT HYBRID FISCHER-TROPSCH CATALYST - A method for forming a catalyst for synthesis gas conversion comprises impregnating a zeolite extrudate using a solution, for example, a substantially non-aqueous solution, comprising a cobalt salt to provide an impregnated zeolite extrudate and activating the impregnated zeolite extrudate by a reduction-oxidation-reduction cycle.06-16-2011
20110160315PROCESS OF SYNTHESIS GAS CONVERSION TO LIQUID HYDROCARBON MIXTURES USING SYNTHESIS GAS CONVERSION CATALYST AND HYDROISOMERIZATION CATALYST - A process is disclosed for converting synthesis gas to a liquid hydrocarbon mixture useful as distillate fuel and/or lube base oil which is substantially free of solid wax. A synthesis gas feed is contacted with a synthesis gas conversion catalyst in an upstream bed and a hydroisomerization catalyst containing a metal promoter and an acidic component in a downstream bed within a single reactor at essentially common reaction conditions. A Fischer-Tropsch wax is formed over the synthesis gas conversion catalyst and said wax is subsequently hydroisomerized over the hydroisomerization catalyst, thereby resulting in a liquid hydrocarbon mixture having a desirable product distribution.06-30-2011
20110240288PROCESS AND SYSTEM FOR BLENDING SYNTHETIC AND NATURAL CRUDE OILS DERIVED FROM OFFSHORE PRODUCED FLUIDS - A process and system are described for the processing of gas associated with crude oil production, i.e. associated gas. A separation complex is used to separate produced fluids produced from a hydrocarbon reservoir into crude oil, liquefied petroleum gas, water, and natural gas. At least a portion of the natural gas is converted into synthesis gas in a synthesis gas generator. A combination of a synthesis gas conversion catalysts and hydroconversion catalysts are used in a synthesis gas reactor to convert the synthesis gas into a liquid effluent stream containing liquefied petroleum gas and a synthetic crude oil. The liquefied petroleum gas and synthetic crude oil from the synthesis gas reactor is sent to the separation complex. Liquefied petroleum gas is separated both from the synthetic crude oil and a natural crude oil obtained from the produced fluids. The system and process permits synthetic crude oil to be blended with the natural crude oil producing a blended stabilized crude oil having 2 wt % or more of the synthetic crude oil and with a pour point of 60° C. or less. Use of a common facility for separation operations on the natural crude oil and synthetic crude oil thus reduces capital costs and allows converted associated gases to be shipped with the natural crude oil on a conventional crude oil tanker.10-06-2011
20110306685PROCESS AND SYSTEM FOR REDUCING THE OLEFIN CONTENT OF A FISCHER-TROPSCH PRODUCT STREAM - A method is provided for converting synthesis gas to liquid hydrocarbon mixtures useful as distillate fuel and/or lube base oil containing no greater than about 25 wt % olefins and containing no greater than about 5 wt % C12-15-2011
20110306686ZEOLITE SUPPORTED RUTHENIUM CATALYSTS FOR THE CONVERSION OF SYNTHESIS GAS TO HYDROCARBONS, AND METHOD FOR PREPARATION AND METHOD OF USE THEREOF - A method for forming a catalyst for synthesis gas conversion and a synthesis gas conversion process impregnating a zeolite support wherein the catalyst contains ruthenium on a zeolite support, such as ZSM-5, ZSM-12, SSZ-32 or beta zeolite, and the product stream has less than 1 weight % C12-15-2011
