Synthesis of Co, Mo, Co-Mo and Mo-Co catalysts, supported on mesoporous silica-alumina for hydrocracking of a-cellulose pyrolysis oil

Abstract

Cobalt, Molybdenum, Co-Mo and Mo-Co catalysts supported on mesoporous silica-alumina (MSA) were synthesized in this work. The MSA and catalysts were characterized by FTIR spectrometer, AAS, TEM, SAA and acidity test (pyridine adsorption). Their catalytic activity were investigated on hydrocracking of a-cellulose pyrolysis oil. The MSA had BET specific surface area of 52.01 m2/g, total pore volume of 0.64 cm3/g and pore diameter of 3.80 nm based on BJH desorption method. The results showed that hydrocracking of a-cellulose pyrolysis oil using Co/MSA, Mo/MSA, Co-Mo/MSA and Mo-Co/MSA catalysts was selective for acetic acid, 1-hydroxy-2-propanone and 2-furancarboxyldehide production. The highest amount of liquid product was obtained by using Co-Mo/MSA catalyst (82.13 wt.%).
