Apparatus and method for conducting a Fischer-Tropsch systhesis reaction.

摘要

A system for a Fischer-Tropsch synthesis using a three-phase reactor (11) in which a primary filter (21) removes coarse catalyst particles from the product and in which catalyst fines are removed in a secondary filter (14). Some or all portion of the product wax from the secondary filter is recycled back to the reactor (11), either as a back flush medium for the primary filter (21) or directly to the slurry in the reactor (11), whereby removal of catalyst fines is rendered independent of the rate of wax production. The system can also comprise a degasser (13) between the primary filter (21) and the secondary filter (14).
