Abstract:
An apparatus for making a hydrocarbon product by a Fischer-Tropsch reaction, comprising:a Fischer-Tropsch slurry bubble column reactor for reacting a synthesis gas in the presence of Fischer-tropsch catalyst particles to produce a slurry comprising liquid hydrocarbon product and Fischer-Tropsch Catalyst particles in said reactor;a slurry output line connected to said slurry bubble column reactor for providing an output of said slurry;a compressed hydrocarbon solvent supply;contacting means connected to said slurry output line and said compressed hydrocarbon solvent supply for contacting said compressed hydrocarbon solvent with said output slurry at a temperature and pressure wherein said liquid product is soluble in said solvent to form a concentrated slurry phase containing said catalyst and an enriched solvent phase containing liquid hydrocarbon product;first separating means connected to said contacting means for separating said concentrated slurry from said enriched solvent; andrecycling means connected to said first separating means for recycling said concentrated slurry to said Fischer-Tropsch slurry bubble column reactor.
