Co-doping of Ni, Cu on CoMo/TiO2 catalyst and their effect on the hydrocracking reaction for the synthesis of BHD (bio-hydrofined-diesel) from animal fat and vegetable oil

BHD (Bio hydrofined diesel) was synthesized from animal fat and vegetable oil by hydrodeoxygenation with CoMo/TiO2 catalyst. To improve the quality and the quantity of BHD, the synthesis co-doping of Ni, Cu on CoMo/TiO2 catalyst and catalytic performance were investiagated. The catalytic performance of various Ni, Cu- CoMo/TiO2 catalysts were studied for the hydrodeoxygention reaction at a range of temperature 300-350 oC. Compared with the hydrodeoxygention reaction with CoMo/TiO2 catalyst, the cetane number of BHD and the conversion reaction were higher when the co-doping catalyst was used. In addition, the quantity of BHD was increased 3-5 % vol when the hydrodeoxygenation reaction was done with co-doping Cu-CoMo/TiO2 catalyst.
