    摘要: This invention relates to a process for producing linear alkyl benzene and linear paraffins, the process including the steps of obtaining a hydrocarbon condensate containing olefins, paraffins and oxygenates from a low temperature Fischer-Tropsch reaction; a) fractionating a desired carbon number distribution from the hydrocarbon condensate to form a fractionated hydrocarbon condensate stream; b) extracting oxygenates from the fractionated hydrocarbon condensate stream from step a) to form a stream containing olefins and paraffins; c) alkylating the stream containing olefins and paraffins from step b) with benzene in the presence of a suitable alkylation catalyst; and d) recovering linear alkyl benzene and linear paraffin.

    摘要: A process for the production of purified water from Fischer-Tropsch reaction water wherein the purified water is an aqueous stream having a COD of between 20 and 500 mg/l, a pH of between 6.0 and 9.0, a suspended solids content of less than 250 mg/l and a total dissolved solids content of less than 600 mg/l, and wherein the process includes at least the steps of a primary treatment stage comprising an equilibrium staged separation process having at least one stage for removing at least a fraction of non-acid oxygenated hydrocarbons from the Fischer-Tropsch reaction water to produce a primary water enriched stream, a secondary treatment stage comprising liquid-liquid extraction for removing at least a fraction of organic acids from at least a portion of the primary water enriched stream to produce a secondary water enriched stream, a tertiary treatment stage comprising biological treatment for removing at least a fraction of acidic oxygenated hydrocarbons from at least a portion of the secondary water enriched stream to produce a tertiary water enriched stream and a quartic treatment stage comprising solid-liquid separation for removing at least some solids from at least a portion of the tertiary water enriched stream.
