A Kinetic Study of Catalytic Cracking of used Cooking Oil to Hydrocarbon Fuels over Sulfated Zirconia
This research aims to upgrading used cooking oil which classified as a waste to liquid hydrocarbon fuels via catalytic cracking in purposed to developed new energy resources for replacement of petroleum fuels. The experiment was performed in microreactor, temperature of 400- 430 C, reaction time of 30 - 90 minutes and pressure of hydrogen gas at 10 - 30 bars over Sulfated Zirconia were investigate via 2k experimental design. Liquid products were analyzed by distillation gas chromatograph and the product distribution was obtained. At the condition of 430 C, reaction time of 90 minutes and hydrogen pressure at 10 bars with 1%wt content of Sulfated Zirconia, gave the highest yield to the gasoline about 26.74% whereas kesosene, gas oil, long residues, gaseous and small solid at about 14.88%, 26.96%, 5.63%,7.58%, 17.43%, and 0.78% respectively. The kinetic study were defined in order to determine the reaction order and the kinetic parameters Ea and A. found that the order of this reaction is second order and kinetic model is k(s-1) = 914.886 exp(-83.439/RT)
