| Abstract: | Recent research on light olefins formation from syngas is reviewed in this paper,including the related F-T synthesis reaction,reaction mechanism and ASF limiting factor.Catalysts are classified according to active metal and carrier.The influences of active metal,assistant,pore structure and acidity on reaction selectivity are investigated.Besides,the technological conditions such as reactor type,temperature,space velocity and pressure are also concluded in order to put forward some suggestions for development of high selectivity and activity catalysts. |
