| Abstract | ||||
| ASERIES of Ni, Mo and Ni-Mo supported alumina catalysts were …….prepared for investigating the interaction between Ni and Mo in terms of their structural properties and catalytic activities.The samples were prepared by wet impregnation with 20 wt% total loading (NiO+MoO) in different molar ratios. The investigated samples were characterized by DSC, TGA, XRD and BET. The catalytic activity and selectivity were studied using isopropanol conversion in flow system under normal pressure at temperature range300-360˚C and space velocity 11.60-18.40 ml.min-1. The reaction products were analyzed using gas liquid chromatography. The main product is acetone and the activation energy is calculated over the investigated catalysts. The results demonstrate that Mo loading enhances formation of NiAl2O4 phase. | ||||
