摘要：In order to shorten the evaluation cycle of cobalt catalyst before the optimized catalyst is fixed on, a mathematical method is proposed to calculate weight percentage of C(5+) hydrocarbons. Based on the carbide polymerization mechanism and the main hydrocarbons being linear alkanes and alpha-olefins, the correlation between hydrocarbon distribution and the molecular mass ratio of water to hydrocarbons is discussed. The result shows the ratio was within the range of 1.125-1.286 and the lower the ratio, the more gaseous hydrocarbons were obtained. Moreover, a linear equation between the weight percentage of C(5+) hydrocarbons and the weight ratio of C(5+) hydrocarbons to the total water is established. These results are validated by corresponding experiments. The weight percentage of C(5+) hydrocarbons could be immediately calculated by this linear equation without detailed gas chromatography (GC) analysis of them.
