Abstract
Crude Palm Oil hydrocrcaking has been carried out over Ni/Mo ZrO2–pillared bentonite catalyst in a fixed bed reactor. Crude Palm Oil hydrocracking over Ni/Mo ZrO2–pillared bentonite catalyst formed 3 products i.e. gas, oil and coke. The oil product from Crude Palm Oil hydrocracking was analyzed by using gas chromatography to determine its composition. Three types of fraction were classified i.e. gasoline, kerosene and diesel oil. In this research, the focused of the study is of hydrocracking kinetics by using lump kinetic models. The kinetic model was solved by using the software MATLAB R2018b involves the effect of catalyst activity on the reaction rate. The results of the kinetic study show that the 4-lump (Crude Palm Oil, gas coke and oil) and 6-lump reaction models (Crude Palm Oil, gas, coke, gasoline, kerosene and diesel) can be used to explain the Crude Palm Oil hydrocracking over Ni/Mo ZrO2–pillared bentonite catalyst. The 4-lump kinetic model has 5 rate constants and the 6-lump kinetic model has 14 rate constants.

Summary
Crude Palm Oil (CPO) obtained from extraction of palm fruit comprise of triglyceride and its free fatty acids This vegetable oils can be converted into fuel through cracking process as reported by several authors. Catalytic hydrocracking of triglycerides contained in vegetable oil undoubtedly involves complex reaction mechanism. Calculation of the lump kinetics model for the hydrocracking reaction involves the catalyst deactivation process. "Kinetic Model of Crude Palm Oil Hydrocracking Over Ni/Mo ZrO2–Pillared Bentonite Catalyst", Periodica Polytechnica Chemical Engineering, 64(2), pp. We presented 4 and 6- lumps kinetic model for Crude Palm Oil hydrocracking over NMBZ catalyst. The appropriate form of rate equation was determined according to 4 and 6-reaction lumps of CPO hydrocracking by involving rate constant; 2. 5. program adopts k which gave smallest SSE (Sum of Squares Errors) value where n is number of data
