    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: The invention provides heat treated self-supported precipitated α-Fe2O3-based Fischer-Tropsch catalyst particles. The catalyst particles are breakage resistant, thus inhibiting the formation of catalyst fines in the Fischer-Tropsch reactor, thereby maintaining the performance of the reactor and reducing the contamination of down stream processes and catalysts by the catalyst fines. The catalyst particles also exhibit superior synthesis performance in low temperature Fischer-Tropsch processes, e.g., slurry bed reactor processes for the production of wax and other syncrudes. The invention also provides a method for producing the particles and a process for using the particles.
