摘要

对含钴工业沸石的费托合成催化剂的理化参数进行了比较分析。在工业尺寸的单管反应器(长- 6000毫米，内径- 12毫米)中对含有导热添加剂(铝片或剥落石墨)的催化剂进行了测试。给出了不加导热添加剂样品的测试结果，以供比较。结果表明，含脱落石墨的载体催化剂具有较高的热稳定性和液态烃产率，适合在合成气高气时空速条件下的工业应用。

Comprehensive Comparison of High-Performance Fischer-Tropsch Synthesis Cobalt Catalysts Containing Different Types of Heat-Conducting Frames

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.
