The effect of operating conditions on the selectivity in the Fischer-Tropsch reaction in a fixed-bed reactor

Fischer-Tropsch synthesis is an important method for producing light olefins. Ethylene and propylene areboth the valuable key raw materials in various industries which are produced in Fischer-Tropschsynthesis. The influence of operating pressure and temperature have been studied on Fischer-Tropschsynthesis liquid hydrocarbon product distribution on a CO-Ni-ZrO2catalyst. Theoptimization of thereaction conditions for the production of ethylene and propylene was investigated. Data analysis indicatedthe highest selectivity for ethylene and propylene at a pressure of 31 atm and a temperature of 529 ° K.The effect of operating conditions on the average carbon number distribution, dispersion, and skewnesswere also studied. Results indicated that the maximum average number of carbonwas obtained in apressureof 1 atm and a temperature of 523°K. Deviation of the distribution also illustrated the distributionof well-focused.
