Comprehensive comparison of high productivity cobalt catalysts for Fischer – Tropsch synthesis with different types of heat-conductive frames

Abstract

The results of physicochemical comparative study of Fischer – Tropsch industrial cobalt zeolite-containing catalysts are presented. The catalysts are based on heat-conductive additive (aluminum flakes or exfoliated graphite) and were tested in one tube industrial scale reactor (length – 6000 mm, inner diameter – 12 mm). For comparison purposes, the testing results of catalyst without heat-conductive additive are presented. It’s shown that exfoliated graphite-based catalyst is more suitable for industrial scale application in high syngas gas hour space velocities due to higher thermal stability and higher hydrocarbon productivity.
