The catalytic hydrogenation of CO2 to CH3OH has a bright prospect along with high market demand. Methanol (CH3OH) was needed as raw material in the petrochemical industry to produce formaldehyde, chloromethane, amine acetate and also as an new alternative environmentally friendly energy. This study aims to obtain a Cu/Zn/Al2O3 catalyst design and the effect of feed temperature on CO2 conversion, CH3OH selectivity, and CH3OH yield. The preparation of Cu/Zn/Al2O3 catalysts by co-precipitation method resulted in the percentage ratio of Cu/Zn/Al metal composition of 66,7: 27,4: 4,29 and the catalyst surface area of 98,3411 m2/g. The H2:CO2 ratio in the feed gas is 3: 1. The fixed-bed reactor has the dimension of 1.5 cm in inner diameter, 5 cm in length of reactor bed, and is equipped by a furnace upstream the reactor bed. The reaction was carried out at the pressure of 30 bar and the flowrate is kept constant. The feed temperature varies at 220, 250, 280°C. At the feed temperature of 250°C, the best performance is obtained: the CO2 conversion of 21.8%, the CH3OH selectivity of 82.76%, and the CH3OH yield of 18.04%, which is reached after 240 minutes of the reaction (steady state).
