Abstract

The Co particle size effect is a topic of interest in Co-based Fischer-Tropsch synthesis catalysis. The effect of CO conversion on various parameters, i.e., CH4 and C5+ selectivities, CO2 selectivity, H2/CO usage, and olefin/paraffin, was studied. CH4 selectivity decreased and C5+ selectivity increased with increasing CO conversion. When CO conversion was over 70%, the decrease in CH4 selectivity and increase in C5+ selectivity decelerated. CO2 selectivity started to increase rapidly at ≈ 70% CO conversion for the Ru-Co/Al2O3 catalyst. Controlling CO conversion below 70% for long-term testing of Co/Al2O3 catalyst possibly minimized CH4 and CO2 selectivities and extended catalyst life. The H2/CO usage ratio decreased from 2.26:1 to 1.9:1 when CO conversion increased from 12% to 94% at a H2/CO feed ratio of 2.1:1. The decreasing H2/CO usage rate with CO conversion was ascribed to an increase in the WGS rate. This is an abstract of a paper presented at the 2011 AIChE Spring Meeting & 7th Global Congress on Process Safety (Chicago, IL 3/13-17/2011).
