Abstract


This study reported preparation, characterizations and application of NiGaCo/MSO catalyst in conversion of CO2 to methanol under mild conditions. The catalyst was characterized by many techniques such as XRD, SEM, TEM, BET and XPS for confirming its structure and element characteristics of active site. The conversion was investigated on effects of many factors including temperature, pressure, feestock compostion to the process performance. The results showed that the NiGaCo/MSO catalyst was high activity and selectivity in the methanol synthesis where the application could be established at mild pressure (15 bar) and temperature (240oC) for a good methanol selectivity (87.8%) and overall yield (32.6%).
