MIXED SUPPORT CATALYST FOR FISCHER-TROPSCH SYNTHESIS AND IT USED LIQUID HYDROCARBON FABRICATION METHOD

摘要

The present invention relates to a mixed support catalyst for Fischer-Tropsch synthesis reaction and a method for producing liquid hydrocarbons using the mixed support catalyst for Fischer-Tropsch synthesis reaction. A method for producing liquid hydrocarbons using a mixed support catalyst for Fischer-Tropsch synthesis reaction according to the present invention comprises: a step (202) of charging a mixed support catalyst into a Fischer-Tropsch synthesis reactor; a step (204) of reducing the mixed support catalyst using hydrogen (H_2); and a step (206) of performing a Fischer-Tropsch synthesis reaction by using the reduced mixed support catalyst. A method for producing liquid hydrocarbons using a mixed support catalyst for Fischer-Tropsch synthesis reaction according to the present invention is capable of improving conversion ratio of carbon monoxide and yield of liquid hydrocarbons while securing stable catalyst activity for a long time by performing Fischer-Tropsch synthesis reaction using a mixed support catalyst for Fischer-Tropsch synthesis reaction in which a catalyst consisting of iron (Fe), copper (Cu) and potassium (K), and a support consisting of gamma aluminum (-Al_2O_3) and silica (SiO_2) are mixed.
