摘　　要：从催化剂、反应条件和反应器等方面对FT合成产物分布的影响做了分析,重点总结了产物分布不遵守ASF规律的研究,并得到如下结论:催化剂活性相可以影响到产物选择性,载体结构通过影响催化剂活性相的分散情况和反应物的扩散阻力而影响产物选择性,碱助剂和金属助剂的加入通过影响活性相的电子云而影响到产物分布,温度、压力、空速和氢碳比等反应条件的影响比较复杂,反应器因为影响到传质传热而影响产物分布。The influences of the catalysts,reaction conditions and the reactors on FT synthetic product distribution are analyzed,with the emphasis on nonobservance of the ASF distribution.And the conclusions were obtained as follows:the active phase of catalyst affects the product distribution out of question.The carrier configuration affects the product distribution by changing the active phase dispersion and diffusional resistance of the reactant,alkali and the metal addtives affect the product distribution by changing the electronic cloud density.It is quite intricate that temperature,pressure,airspeed and H2/CO ratio affect the product distribution.The reactor affects the product distribution owing to the mass transfer and heat transfer changed.
