Abstract: A method to produce a fuel product such as jet fuel, diesel or single battlefield fuel from a Fischer Tropsch syncrude comprising the steps of: 1) Separating the HFTL product from the reactor effluent gasses at reactor temperature and partially cooling the reactor effluent gas before transferring it to the enhanced hot separator; 2) enhancing the hot separator downstream of the Fischer Tropsch reactor with trays or packing and also adding reflux of the LFTL product, to improve separation efficiency and substantially reduce the C16+ portion of the hydrocarbons in the LFTL product; 3) combining the HFTL and MFTL product to from a combined HFTL product and further processing the combined HFTL in a hydroprocessing reactor that has a stacked bed with a layer of hydrocracking catalyst to crack the waxy C20+ hydrocarbons and a layer of hydroisomerization catalyst to isomerize the light fraction to increase the iso to n-paraffin ratio of the hydroprocessed product; 4) the LFTL product that is not recycled to the hot separator as reflux, bypasses the hydroprocessing reactor and is blended with the hydroprocessed product before distillation; and 5) the combined raw LFTL product and the hydroprocessed product is distilled to make naphtha, a fuel product, and a baseoil product. The method may be modified to make a single fuel product, preferably a jet fuel product.

Abstract: An integrated process for converting light hydrocarbon gases into products. Pre-packaged equipment such as a gas turbine and process compressors may be used to efficiently integrate the process. The gas turbine may provide all or a portion of the oxygen required in the process as compressed air. The turbine may be configured with a gradual oxidizer that can oxidize the process tail gas and drive the turbine, providing power for the process.

Abstract: A process to convert paraffinic feedstocks into renewable poly-alpha-olefins (PAO) basestocks. In a preferred embodiment of the invention, renewable feed comprising triglycerides and/or free fatty acids are hydrotreated producing an intermediate paraffin feedstock. This paraffin feedstock is thermally cracked into a mixture of olefins and paraffins comprising linear alpha olefins. The olefins are separated and the un-reacted paraffins are recycled to the thermal cracker. Light olefins preferably (C2-C6) are oligomerized with a surface deactivated zeolite producing a mixture of slightly branched oligomers comprising internal olefins. The heavier olefins (C6-C16) are oligomerized, preferably with a BF3 catalyst and co-catalyst to produce PAO products. The oligomerized products can be hydrotreated and distilled together or separate to produce finished products that include naphtha, distillate, solvents, and PAO lube basestocks.

Abstract: A process to convert light hydrocarbons such as natural gas to a liquid or liquids. Vacuum pressure swing adsorption (VPSA) is used to produce a stream of relatively high purity oxygen. The relatively high purity oxygen is reacted with light hydrocarbons and steam in a partial oxidation reactor in order to produce synthesis gas. The synthesis gas is thereafter converted to a hydrocarbon liquid or liquids via a Fischer Tropsch or related reaction.

Abstract: A process for converting carbonaceous materials or light hydrocarbon gases into products comprising predominately C5+ hydrocarbons. The process converts the feedstock into synthesis gas comprising hydrogen and carbon monoxide and then uses the Fischer-Tropsch reaction to produce heavy hydrocarbons. A small excess of hydrogen is produced in the syngas generator or by water gas shift for use in product upgrading and for blending with Fischer-Tropsch tail gas for recycle back to syngas generation. A portion of the Fischer-Tropsch tail gas is used as fuel, thus purging combustible light gases and CO2 from the tail gas. Hydrogen rich purge gas is blended into the remaining tail gas resulting in a recycle stream that is returned to the syngas generator. The tail gas components are therefore efficiently used to produce more products.

Abstract: A method for enhancing the heat transfer performance of a vertical tubular reactor by adding heat transfer elements inside the reactor tubes. Such heat transfer elements have two or more substantially curved legs of equal length with no cross fins, each with a foot that engages the inside wall of the tube, and can optionally have two or more substantially curved sub-legs that do not engage the wall of the tube.

Abstract: A method is disclosed for rejuvenation a cobalt Fischer Tropsch catalyst used in a Fischer Tropsch process operating in recycle mode. The method permits the use of specific inert gases to adjust the mole weight of the gas so that the recycle compressor designed for normal steady state operation can also be used in the method. Hydrogen from a membrane permeate stream is added to the reactor loop at a temperature between 300 F and 400 F and the carbon oxides are reacted out to purify the hydrogen. This stream is continuously recycled and the temperature is raised to between 425 F and 500 F and held at the final temperature for between 4 hours and 48 hours. The cobalt Fischer Tropsch catalyst is effectively rejuvenated in-situ by the method.
