A METHOD FOR CONDUCTING FISCHER-TROPSCH SYNTHESIS REACTION

摘要

A method for conducting Fischer-Tropsch synthesis reaction comprising the following steps: i) introducing gas raw materials containing CO and H2 into a Fischer-Tropsch reactor, and reacting with each other under a controlled reaction condition and thereby generating hydrocarbon products containing two or more carbon atoms, and gaseous byproducts containing H20, CH4 and C02, wherein the controlled reaction condition reduces the single-cycle conversion rate of CO; ii) taking at least a portion of the tail gas from step (i) and mixing them with fresh gas raw materials containing CO and H2, removing C02 and water from the mixed materials; iii) introducing the gas materials from step (ii) into the Fischer-Tropsch reactor and repeating steps (i) and (ii). The method of the present invention can reduce water content in the reaction system by a recycling operation and a dewaterization unit, and decrease the possibility of inactivation of cobalt-based catalysts caused by moisture.
