Hydrotreatment of Cellulose-Derived Bio-Oil Using Copper and/or Zinc Catalysts Supported on Mesoporous Silica-Alumina Synthesized from Lapindo Mud and Catfish Bone

Catalysts comprising copper and/or zinc supported on mesoporous silica-alumina (MSA) with a high Si/Al ratio were prepared by wet impregnation method. This study investigated the preparation, characterization, and catalytic application of the prepared catalysts for hydrotreatment of cellulose-derived bio-oil. The wet impregnation was performed by dispersing Cu(NO3)(2)center dot 3H(2)O and/or Zn(NO3)(2)center dot 4H(2)O aqueous solution into MSA, followed by calcination and reduction under H-2 gas stream. The acidity test revealed that metal addition on MSA support increases the acidity of catalysts. During hydrotreatment of cellulose-derived bio-oil CuZn/MSA with total acidity, copper loading, zinc loading, and specific surface area of 24.86 mmol g(-1), 5.23 wt.%, 3.15 wt.%, and 170.77 m(2) g(-1), respectively, exhibited the best performance compared to other prepared catalysts with 90.49 wt.% conversion of liquid product.
