KATALIS BIMETAL Cu-Cr/DIATOMEA UNTUK HIDROGENASI MINYAK SAWIT
Abstract: A series of
bimetallic Cu-Cr supported onto diatomite was synthesized using impregnation
method and characterized using X-ray diffractometer (XRD) technique. The
catalyst compositions were CuCrO2, Cu2O, Al2O3 and SiO2. The catalyst contained
5, 10, 20, and 30 wt.% of Cu-Cr
respectively, with Cu : Cr ratio of 1:1. The catalytic performance of the
samples was evaluated based on the application to a hydrogenated palm oil at 70oC and 7 bar of pressure by
measuring its iodine number. The result showed that the bimetallic Cu-Cr
deposited onto diatomite was an effective catalysts for hydrogenation of palm
oils and its catalytic activity was highly dependent on the composition of
metals. Iodine number of palm oil decreased to 27.2 from 43.28 by using of 30 wt.% of Cu-Cr after
120 minutes reaction almost similar to
the performance of commercial nickel catalyst that could decrease the iodine
number to 26.1.
