Fischer-Tropsch synthesis is an important method for producing lightolefins. Ethylene and propylene are both the valuable key raw materials invarious industries which are produced in Fischer-Tropsch synthesis. Theinfluence of operating pressure and temperature have been studied on liquidhydrocarbon product distribution by CO-Ni-ZrO2 catalyst. The optimizationof the reaction conditions for the production of ethylene and propylene wasinvestigated. Data analysis indicated the highest selectivity for ethylene andpropylene at a pressure of 31 atm and a temperature of 529°K. The effect ofoperating conditions on the average carbon number distribution, dispersion,and skewness were also studied. Results indicated that the maximumaverage number of carbonwas obtained in a pressureof 1 atm and atemperature of 523°K. Deviation of the distribution also illustrated thedistribution of well-focused.
