Abstract


Hereby, we are describing the synthesis and characterization concerning acid -basic properties of catalysts containing varied amounts of NiMo (2-14 wt % of NiMoO4) worn on copper orthophosphate whose its preparation was executed employing a co-precipitation method, to which we introduced the Nickel-Molydenum by impregnation with a porous volume at several stages, succeeded by calcination under air at a different temperature. The employed techniques for solids’ characterization were XRD to identify different phases, Nitrogen adsorption at-196°C. and catalytic conversion of isopropanol at different temperatures’ reaction ranging from 180 to 400 °C. The outcome revealed that the solids NiMo/CuP mainly consisted of copper phosphate Cu3 (PO4)2 together with NiMoO4 as minor phase. The NiMoO4 crystallinity’s degree increases by increasing Nickel-Molydenum. It was discovered that the specific area (SBET) of the studied system will slightly increase by the increase in NiMoO4 content. The catalytic activity in isopropanol conversion which proceeds via dehydration yielding propene increases as a function of extent of loading.
