摘      要：The effect of operating conditions on the O/P ratios of hydrocarbons produced from FTS over Fe/Cu/K catalyst was studied in a continuously stirring tank reactor (CSTR, Autoclave Engineers) under conditions of T= 515 -542 K, GHSV = 576-906 h-1 and H2/CO ratio= 1. 12 to 3.97. The O/P ratios of hydrocarbons with different carbon numbers may increase, decrease or keep constant with the increase of reaction temperature, GHSV and H2/CO ratio in reactor, respectively. The O/P ratios decrease with the increase of carbon numbers of hydrocarbons and the effect of operating conditions on the O/P ratios trends to decrease with the increase of carbon numbers from three to fifteen. The ratio of ethylene to ethane is always very low and almost independent of the change of operating conditions which indicates that the ethylene may participate in the process of chain growth.
