Daftar Isi:
- The preparation and the activemetal content influence the activity of catalyst. Study has been conducted to see the activity of Ni/kieselguhr based on preparation mehod and Nickel (Ni) contents in the catalyst in the laboratory scale. The Ni/kieselguhr catalyst were prepared by impregnation and precipitation methods, with Ni active contents of 10, 20, and 30% by weight. The catalysts characterization was analyzed using X-Ray Diffraction (XRD). Catalysts activities were analyzed based on decreasing of iodine number from hydrogenation of crude palm oil for 2 hours. The activity tests results show that precipitation catalysts are more active than impregnation catalysts. The decreasing in iodine number of fatty acid after 2 hours of hydrogenation process using precipitation catalysts and impregnation catalysts are 51.53 and 21.85%, respectively. In addition, the catalysts are more active with increasing Ni contents.Keywords: Precipitation, Impregnation, XRD, Hydrogenation of crude palm oil, Iodine number.
