| Abstract | : | Analysis of cobalt concentration-effect supported on mesoporous silica (MS) has been evaluated. This study was aimed to observe the physical and chemical characteristics of the catalysts, and also to study the catalytic activity and its selectivity toward gasoline and diesel oil products in the hydrocracking process of waste coconut oil. The MS was produced using Lapindo mud where the CTAB was used as the mesopore templating agent. The Co/MS catalyst was prepared by the wet impregnation method with the various concentration of Co. The characterization of the catalyst includes silica purity test by XRF, determination of Co content by AAS, the crystallinity by XRD, the catalyst porosity by SAA, physical pore structure by SEM and TEM, and total acidity by the gravimetric method using NH3 base vapor adsorption. The hydrocracking was carried out in a hydrocracking reactor using various concentrations of Co/MS catalysts with the ratio of catalyst/feed = 1/50. The products of the hydrocracking process were liquid, coke, and gas. The composition of the hydrocracking liquid products was analyzed by GC-MS. Based on the results of the catalytic activity test, it concluded that the Co(1)/MS catalyst which has the highest acidity showed the best catalyst selectivity towards gasoline and diesel fractions. |
