ABSTRACT

Fischer–Tropsch (FT) process is a promising method for producing liquid fuels and other valuable chemicals through CO hydrogenation. The catalyst activity and product selectivity can be strongly affected by different parameters such as support and promoters. The physicochemical and textural properties of the support affect the metal–support interaction, crystallite size, metal dispersion, mass transfer of reactants/products, mechanical strength, and thermal stability of the catalyst. Promoters can also be used as structural, textural, electronic modifier, stabilizers, and catalyst-poison-resistant, which can improve the catalytic performance. According to the parameters mentioned above, this paper reviews the brief history of the FT process, the effect of different supports and promoters on the catalytic performance of cobalt-based catalysts. In addition to the catalyst properties, the reactor must also be designed appropriately to handle the heat of this highly exothermic reaction. The reactor types have also been reviewed and compared as a crucial part of the catalytic reactions.

摘要

Fischer-Tropsch (FT) 工艺是一种通过 CO 加氢生产液体燃料和其他有价值化学品的有前途的方法。催化剂活性和产物选择性会受到不同参数（例如载体和促进剂）的强烈影响。载体的物理化学和结构特性影响金属-载体相互作用、微晶尺寸、金属分散、反应物/产物的传质、机械强度和催化剂的热稳定性。促进剂还可用作结构、质构、电子改性剂、稳定剂和催化剂抗毒剂，可提高催化性能。根据上述参数，本文综述了FT工艺的简史，不同载体和助催化剂对钴基催化剂催化性能的影响。除了催化剂性能外，反应器还必须适当设计以处理这种高度放热反应的热量。反应器类型也作为催化反应的关键部分进行了审查和比较。
