Study On Liquid Fuel Synthesis Co-production With Higher Carbon Alcohol

The technology of producing liquid fuel with Fischer-Tropsch Synthesis is an important way to solve China's energy shortage. The study on reaction kinetics guides the optimal operation of Fischer-Tropsch Synthesis reactors. In this thesis based on the study on Co/AC catalyst's performance the lumping kinetics model consisted of CO consumption rate.With the characterization methods of SEM,BET,TPR and so on. The results showed that the catalyst contained a mixture structure of micropore and mesopore and could be activated in pure H2, and the fit reduction temperature was 350-400℃. The experiments was conducted in the isothermal integral reactor and the effects of pressure,temperature,H2-/CO and sapce velocity on the reaction results was studied. The results showed that a reaction condition containing high temperature, high pressure, high value of H2/CO (mol) in syngas and low Space Velocity (Sv) was propitious to increase the reaction activity of catalyst and the conversion of CO. Meanwhile, the increase of pressure and the decrease of temperature, Sv and H2/CO (mol) would result in the increase of selectivity to hydrocarbons and alcohols with high carbon numbers.The CO conversion of the intrinsic kinetics model was showed as:Through statistical tests and residual analysis, this model was appropriate. Calculational data of CO conversion of the intrinsic kinetics model shoe good agreement with the experimental data.
