Synthesis of ni/mesoporous silica-alumina using sidoarjo mud and bovine bone gelatin template for hydrocracking of waste lubricant

Abstract

Synthesis of Ni/mesoporous silica-alumina (MSA) with silica from Sidoarjo mud using bovine bone gelatin as a template and its activity for hydrocracking of waste lubricant have been investigated. Nickel was loaded onto MSA using wet impregnation (WI) and ion exchange (IE) method. MSA-100 has optimum thermal stability, the acidity of 72.89 mmol/g, the pore diameter of 3.37 nm, the surface area of 230.73 m2/g, and a pore volume of 0.87 cm3/g. Ni content of MSA-100 (WI) and (IE) was 0.48 and 0.08 wt.%, respectively. Ni/MSA-100(IE) produced the highest amount of liquid with gasoline and diesel content of 49.05 and 14.09 wt.% on hydrocracking of waste lubricant.
