Recent advances in designing and preparing catalysts for Fischer-Tropsch synthesis with emphasis on effective control of product distribution were highlighted. The effects of pore sizes of supports(particularly molecular sieves and carbon materials with ordered porous structure) as one of the key properties of a catalyst and the nature of various promoters on activities and product selectivities of Fe-, Co- and Ru-based catalysts were analyzed systematically. The effects of active metal particle sizes in relevant catalytic systems were also discussed in detail. This review also summarized recently developed novel catalytic materials, novel catalyst preparation methods and novel catalytic systems.
