Integrated fuel processing with biomass oil
A gas to liquids process with a reduced CO.sub.2 footprint to convert both natural gas and a renewable feedstock material into fuels or chemicals. In one embodiment of the invention, a natural gas feed is converted into synthesis gas containing hydrogen and carbon monoxide. A minor portion of the hydrogen is thereafter extracted from the synthesis gas. The synthesis gas is converted to hydrocarbons in a Fischer Tropsch reaction. The Fischer Tropsch hydrocarbon product and a renewable feedstock are hydroprocessed with the extracted hydrogen in order to produce fuels and/or chemicals. Waste products from the renewable feed are recycled to produce additional synthesis gas for the Fischer Tropsch reaction.
Renewable fuels co-processing
A gas to liquids process with a reduced CO.sub.2 footprint to convert natural gas and a renewable feed stock material into fuels or chemicals. In one non-limiting embodiment of the invention, a natural gas feed is converted into synthesis gas containing hydrogen and carbon monoxide. A minor portion of the hydrogen is thereafter extracted from the synthesis gas. The synthesis gas is converted to hydrocarbons in a Fischer Tropsch reaction. The Fischer Tropsch hydrocarbon product and a renewable feedstock are hydro processed with the extracted hydrogen in order to produce fuels and/or chemicals. Waste products from the renewable feed are recycled to produce additional synthesis gas for the Fischer Tropsch reaction.
Catalyst for low temperature slurry bed Fischer-Tropsch synthesis
A method for controllably producing a hematite-containing Fischer-Tropsch catalyst by combining an iron nitrate solution with a precipitating agent solution at a precipitating temperature and over a precipitation time to form a precipitate comprising iron phases; holding the precipitate from at a hold temperature for a hold time to provide a hematite containing precipitate; and washing the hematite containing precipitate via contact with a wash solution and filtering, to provide a washed hematite containing catalyst. The method may further comprise promoting the washed hematite containing catalyst with a chemical promoter; spray drying the promoted hematite containing catalyst; and calcining the spray dried hematite containing catalyst to provide a calcined hematite-containing Fischer-Tropsch catalyst.
Catalyst for selective synthesis of lower hydrocarbons from syngas

The catalyst shows a surprising increase in hydrocarbons and wax formation at high temperature and a much higher specific catalyst activity than demonstrated to date. More generally, a catalyst support, method of making a catalyst, and methods of FT synthesis are described.
FISCHER-TROPSCH CATALYST ACTIVATION
The present disclosure relates generally to processes for activating Fischer-Tropsch synthesis catalysts. In particular, the application concerns a process for the activation of a Fischer-Tropsch synthesis catalyst, the process comprising: (i) contacting the catalyst with a first gaseous composition comprising at least 80% N.sub.2 at a pressure in the range of 2 barg to 20 barg at a temperature of no more than 150 C.; (ii) contacting the catalyst with a second gaseous composition comprising at least 80% H.sub.2 to form a H.sub.2/N.sub.2 gaseous composition with a H.sub.2:N.sub.2 molar ratio in the range of 0.2:1 to 2:1, resulting in a pressure in the range of 10 barg to 30 barg; (iii) increasing the temperature to a range of 220 C. to 260 C.; (iv) maintaining the catalyst at the conditions of step (iii) for a hold period in the range of 2 hr to 96 hr.

The present disclosure relates generally to titania-supported Fischer-Tropsch catalysts incorporating manganese titanate, methods of making and use thereof. In one aspect, the present disclosure provides a titania-supported Fischer-Tropsch catalyst precursor comprising a titania support, and disposed on the titania support, manganese in the range of 1 wt % to 20 wt %, calculated as manganese (0); wherein at least 10 at % of the manganese is in the form of MnTiO.sub.3.
Treating of catalyst carrier, fischer-tropsch catalysts and method of preparation thereof
A method for the preparation of a modified catalyst support comprising: (a) treating a bare catalyst support material with an aqueous solution or dispersion of one or more titanium metal sources and one or more carboxylic acids; and (b) drying the treated support, and (c) optionally calcining the treated support. Also provided are catalyst support materials obtainable by the methods, and catalysts prepared from such supports.
Preparing phosphorus containing alumina support by sol-gel method for Fischer-Tropsch synthesis and catalyst preparation thereof
The present invention relates to a process of preparing of a phosphorus-containing phosphorus-alumina support by a sol-gel method and a cobalt/phosphorus-alumina catalyst where cobalt is supported onto the phosphorus-alumina support as an active ingredient. The phosphorus-alumina support is prepared by a sol-gel method and has wide specific surface area with bimodal pore size distribution and high cobalt dispersion, thereby enabling to increase heat and mass transfer, stabilize the structure by modifying the surface property of alumina and decrease the deactivation rate due to the reduced oxidation of cobalt component during the F-T reaction. When Fischer-Tropsch reaction (F-T) is conducted on the catalyst, the catalyst maintains a superior thermal stability, inhibits the deactivation due to water generation during the F-T reaction and also causes relatively high conversion of carbon monoxide and stable selectivity of liquid hydrocarbons.
