利用费托合成制取液体燃料的研究进展

Further Research and Application of the Synthesis of Liquid Fuel Via Fischer-Tropsch Synthesis

费托合成可以用煤基合成气、天然气以及生物质气等为原料来制取液态燃料。该合成反应的催化剂有铁催化剂和钴催化剂,铁催化剂具有高时空产率,而钴催化剂具有较高的选择性和稳定性。费托合成的机理目前还没有统一说法,对几种比较流行的机理做了简单介绍。费托合成的设备有固定床反应器、流化床反应器和浆态床反应器,从发展趋势来看,浆态床是F-T合成反应器的主要发展方向。

Fischer-Tropsch synthesis can be used to produce liquid fuel with coal-based synthetic gas, biomass and natural gas as raw materials. There are two kinds of catalyst for the reaction： iron catalyst, which is with high temporal and spatial yield, and cobalt catalyst, which is with high selectivity and stability. There is no uniform view of the mechanism of F-T synthesis, this paper gives a brief introduction of some more popular ones. On the equipment, there are fixed-bed reactor, fluidized bed reactor and slurry reactor. The slurry bed will be the development trend of the FT synthesis reaction.
