Abstract: A method and a system for drying a biomass, wet pulverized coal or combinations thereof, using heat from a Fischer-Tropsch synthesis in a heat exchanger to heat a nitrogen gas, using a flue gas in a heater to heat the heated nitrogen gas to a higher temperature, passing the twice heated nitrogen gas through apparatus to pulverize the fuel source of coal, biomass or both, forming a gas/particulate stream, filtering the gas/particulate stream in a filter to remove dried fuel feed stocks and using a blower to form a first steam and nitrogen mixture for discharge, and a second steam and nitrogen mixture for mixing with additional dry nitrogen gas for introduction to the first step of the method, at the heat exchanger.
Abstract: The invention provides a catalytic distillation system which combines two fundamental unit operations, chemical reaction and distillation in a single piece of equipment for hydrocracking and hydrotreating of Fischer-Tropsch liquids.
Abstract: The invention provides a process for desalting crude by combining water and raw crude oil in a mixer to produce a mixture. Desalted crude oil and a brine mixture are separated from the mixture. The water is obtained as a byproduct of a Fischer-Tropsch plant.

Abstract: A fuel cell system and a method of producing electricity in a fuel cell are described. The fuel cell system includes a reformer for converting an unreformed fuel to produce a reformate fuel gas; and a fuel cell stack adapted to generate electricity using the reformate fuel gas. The unreformed fuel is a solid paraffinic hydrocarbon. Some hydrocarbons include at least about 5 wt. percent olefins; at least about 5 wt. percent n-paraffins; and between about 2 and 50 wt. percent branched paraffins wherein substantially all of the branch groups are monomethyl and wherein the ratio of terminal monomethyl branching to internal monomethyl branching is at least about 1:1.5.
Abstract: A process to optimize the condensation of Fischer-Tropsch products coming from the Fischer-Tropsch reactor in a vapour phase with the use of light oil and, therefore; reducing the possibility of coating the coolers and piping with waxy material.
Abstract: A process to optimize a slurry Fischer-Tropsch catalyst life and to further optimize removal of debris from a slurry Fischer-Tropsch process is provided. The process passes a part of a Fischer-Tropsch Reactor slurry inventory to another upstream Fischer-Tropsch Reactor where the Fischer-Tropsch reactors are connected in series. The process utilizes either multiple or a single transfer vessel and optionally, a motive gas.
Abstract: A process to control the amount of N-contaminant is synthesis gas which is fed into a Fischer-Tropsch reactor and which utilizes Fischer-Tropsch produced water is provided. A process which utilizes a countercurrent flow of Fischer-Tropsch produced water produced in a downstream Fischer-Tropsch reactor to wash syngas being fed to an upstream Fischer-Tropsch reactor is provided.
Abstract: A Fischer-Tropsch-based hydrocarbon conversion process involves compressing air in a compressor section of a gas turbine, delivering a portion of the compressed air to a combustor of the gas turbine, delivering a portion of the compressed air to a Fischer-Tropsch hydrocarbon conversion unit, extracting thermal energy from the combustor and delivering it to the Fischer-Tropsch hydrocarbon conversion unit, converting light hydrocarbons into heavier hydrocarbons in the Fischer-Tropsch hydrocarbon conversion unit, and delivering combustion gases from the combustor to an expansion section of the gas turbine. A heat recovery steam generator (HRSG) may also be used to harness waste heat from the expansion section. A conversion system for converting light hydrocarbons into heavier hydrocarbons includes a turbine from which heat energy is removed and used to assist in converting hydrocarbons and whereby greater throughput of the turbine is possible.
Abstract: A process for regenerating a slurry Fischer-Tropsch catalyst, which needs regeneration, involves de-waxing and drying the catalyst sufficiently to produce a free-flowing catalyst powder that is fluidizable; fluidizing the catalyst powder; treating the catalyst powder with an oxygen treatment; reducing the catalyst powder with a reducing gas to form a reduced catalyst powder; and mixing the reduced catalyst powder with hydrocarbons to form a regenerated, slurry catalyst. The oxidation and reduction steps may be repeated. An oxygen treatment includes using a fixed O2 level with ramped temperatures, fixed temperatures with increased O2 levels, or a combination.
