[0046] The preparation process of the Fischer-Tropsch synthesis catalyst used in the examples is as follows: take aluminum oxide powder, add distilled water dropwise to incipient wetness, record the volume of consumed water, and then calculate according to the Co content (oxide basis) 27% by weight, prepare the Cobalt nitrate impregnation solution. Then impregnate alumina with this solution to incipient wetness, let it stand for 8 hours, then dry it at 120°C for 4 hours, and bake it in a muffle furnace at 450°C for 4 hours to prepare the catalyst. The particle size range of the obtained cobalt-based Fischer-Tropsch synthesis catalyst is 1.2-1.6 mm.
[0047] In this embodiment, the Fischer-Tropsch synthesis reactor adopts a reaction tube with an inner diameter of 32 mm. The porous surface layer is manufactured by iron alloy powder sintering process. The thickness is 3mm.
[0048] Fischer-Tropsch synthesis process conditions are: raw material synthesis gas volume space velocit...
