[0054] 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.
[0055] There are 300 reaction tubes in the Fischer-Tropsch synthesis tubular fixed bed reactor. The reaction tubes are made of austenitic stainless steel pipes with an outer diameter of 38 mm and a wall thickness of 3 mm. The groove has a depth of 1.2mm, an average groove width of 0.6mm, and a helix angle of 4°.
