SLURRY PHASE FISCHER-TROPSCH SYNTHESIS OVER MANGANESE-PROMOTED IRON ULTRAFINE PARTICLE CATALYST

摘要

The reaction performance of manganese-promoted ultrafine particle(UFP) iron catalyst for liquid phase Fischer-Tropsch(FT) synthesis was investigated in a stirred tank slurry reactor under reaction conditions representative of industrial practice(260-300℃, 1.5-2.5MPa,1.5-2.5NL/gcat/h, H_2/CO=0.65-2.0). The Fe/Mn UFP catalyst showed high single-pass CO conversion and gave high yields of C_2-C_4 olefins.
