Abstract
Hydrogenation of crude palm oil using in-house prepared 1% palladium on activated carbon catalyst was studied in a stirred type reactor in attempt to establish kinetics regime of the reaction. Preliminary runs showed hydrogenation raising to similar effect on oil color as bleaching and the use of bleached oil was preferable due to less catalyst deactivation by oil impurities. Initial rate analysis indicates that the reactions occurred in kinetics regime at stirring speeds above 1000 rpm and catalyst loadings less than 0.4 g/L. Arhenius plot analysis confirms kinetics regime finding. The reaction mechanism was proposed to follow Langmuir-Hinshelwood kinetics.
Keywords: palm oil; hydrogenation; palladium; hardening
