Synthesis of molybdenum-based catalysts on carbon support for partial hydrogenation reaction of biodiesel

Abstract

Nowadays, biodiesel is a renewable energy, which can decrease�fossil fuel. It helped reducing air pollution. Partial Hydrogenation is one process�which�improves the biodiesel quality. In this research, activated carbon was produced from cattail leave via hydrothermal carbonization and chemical activation. The activated carbon was treated with 4 M of potassium hydroxide at 900oC, which exhibits 1323.38 m2g-1�of SBET. Several�type of catalysts (Mo, Ni, Ci, Fe, MoNi, MoCu, and MoFe) were studied in this research, which were prepared using a�rotary evaporation technique. The experiments reveal that MoNi/C catalyst indicate the highest dispersion of metal particle. The catalyst performance was evaluated by partial hydrogenation of soybean FAME,100oC and 4 bar. MoNi/C catalyst provided the best activity, which exhibits 19% conversion of C18:2 and C18:3 with less trans-C181 and C18:0. The oxidation stability was less�after the hydrogenation of reaction,�it was found to increase by 14.56 h. Moreover, the cold flow properties were determined in which the cloud point was 13�oC and the pour point was 10�oC.
