Abstract

Modification of a palladium-supported catalyst was performed in order to improve its activity and transisomerisation selectivity (Si) for palm oil hydrogenation. A Pd-B/-γl2O3 amorphous alloy was prepared by wet impregnation of Pd (acac)2 on -γl2O3 followed by chemical reduction using KBH4. The catalyst was thermally treated at 573 K before hydrogenation and was characterised by the Brunauer-Emmett-Teller surface areas (BET), scanning electron microscopy (SEM) and Transmission electron microscopy (TEM). A conventional hydrogenation for palm oil was performed using 0.12 % catalyst at 393 K, 500 kPa and 500 rpm for 1 h. The Pd-γl2O3 catalyst exhibited significantly better catalytic activity and trans selectivity comparing to the corresponding Pd/-γl2O3 and commercial catalysts.
