Kinetic Study of Catalytic Hydrocracking Ceiba Pentandra Oil to Liquid Fuels over Nickel-Molybdenum/HZSM-5

Abstract

The conversion of Ceiba pentandra oil to catalytic hydrocracking are suitable ways for biofuel. The focus of this study is to use Ceiba Pentandra oil catalytic hydrocarbon cracking and determine the alternative to petroleum fuels. The conversion of the Ceiba pentandra oil was carried out using a batch reactor, type 4563 PARR with a volume of 200 ml. This conversion process is done by varying the temperature factor (300-400°C), the reaction time over the range of 30-120 minutes and hydrogen pressure over a range of 30 bars using NiMo/HZSM-5. The conditions for the highest conversion of gasoil (C15-C18) as much as 43.78% were temperature of 400 minutes. The same conditions for kerosene (C9-C14) and long hydrocarbon chains (>C18) were present at 4.93% and 2.85% respectively. The kinetic study was determined to determine the order and kinetic parameters of activation energy (Ea) of 84,266 kJ.kgmol-1K-1and the exponential factor from the Arrhenius relationship. The order of this reaction has been determined of the first order and the kinetic model is defined as . Ceiba pentandra oil triglycerides hydroconversion pathways were dependent on temperature and reaction time. The triglycerides could be hydrocracked to lower range hydrocarbons (C9-C14) by increasing the reaction temperatures.
