Synthesis and characterization of ni-nh2/mesoporous silica catalyst from lapindo mud for hydrocracking of waste cooking oil into biofuel

The synthesis and characterization of Ni-NH<inf>2</inf>/Mesoporous Silica (MS) catalysts from Lapindo mud for the hydrocracking of waste cooking oil into biofuel has been conducted. The MS was synthesized by the hydrothermal method using CTAB as a template. The functionalization of �NH<inf>2</inf> into MS was carried out by the grafting method. The Ni metal was loaded into NH<inf>2</inf>/MS by wet impregnation. The catalytic activity test was done for hydrocracking of waste cooking oil by using the MS, NH<inf>2</inf>/MS, and Ni-NH<inf>2</inf>/MS catalysts. The results of the liquid product of the hydrocracking were analyzed by the gravimetric method and GC-MS. The experimental result showed that the liquid products of the hydrocracking using MS, NH<inf>2</inf>/MS, and Ni-NH<inf>2</inf>/MS catalysts were 63.95, 70.32, and 66.44 wt.. The highest selectivity of the gasoline fraction (34.98 wt.) was produced by the NH<inf>2</inf>/MS catalyst and the highest diesel oil fraction (1.52 wt.) was produced by MS. The NH<inf>2</inf>/MS catalyst was successfully used as a catalyst in the hydrocracking of waste cooking oil into the hydrocarbons (biofuel). © 2020 Elsevier B.V., All rights reserved.
