Synthesis of mesoporous carbon (MC) from bovine bone gelatin, NiMo/MC catalyst and MoNi/MC catalyst for hydrocracking of lubricant waste have been conducted. The Gelatin was extracted from bovine bone using CH3COOH, NaOH and HCl. The MC was synthesized using bovine bone gelatin as a carbon source and SBA-15 as a template. The Ni and Mo metals were loaded onto the MC by wet impregnation method. The MC material was characterized by FTIR spectrometer, TEM, SEM, and SAA. The NiMo/MC and MoNi/MC catalyst were characterized by SEM-EDX and SAA. The acidity of catalysts was determined by a gravimetric method using ammonia base vapor as the adsorbate. The catalytic activity test was conducted on the hydrocracking of lubricant waste. The liquid fraction of the hydrocracking product was analyzed using GC-MS. The research results showed that the MC material has a pore diameter, surface area, total pore volume, and acidity of 7.52 nm, 404.47 m2/g, 0.76 cm3/g, and 5.01 mmol/g, respectively. The highest liquid fraction (64.15%) as a hydrocracking product of the lubricant waste was obtained using MoNi/MC catalyst at a lubricant/catalyst weight ratio of 300 which contains gasoline, diesel and heavy oil fraction of 45.58, 9.99 and 0.78 wt.%, respectively. © RASĀYAN.
