Abstract
A comparative analysis of industrial zeolite-containing cobalt catalysts for Fischer-Tropsch synthesis with a number of physicochemical parameters is performed. Catalysts containing a heat-conducting additive (aluminum flakes or exfoliated graphite) were tested in an industrial size single-tube reactor (length—6000 mm, inner diameter—12 mm). The testing results of a sample without heat-conducting additive are presented for comparison. It is shown that a catalyst based on support, containing exfoliated graphite is preferable for industrial application at high gas hour space velocities of the syngas due to its higher thermal stability and liquid hydrocarbon productivity.
