Abstract:
Methanol synthesis from synthesis gas (syngas, a mixture of hydrogen (H2) and carbon monoxide (CO)) in the presence of copper/zinc oxide/alumina catalyst (Cu/ZnO/Al2O3) was investigated using semi-batch reactor. The process was operated at 280 Celsius degrees under pressure 40 bar in a slurry reactor (Parr reactor model 4848). The catalyst weight, syngas molar ratio and residence time were optimized for methanol synthesis. Cu/ZnO/Al2O3 catalyst was prepared by a two-step surfactant assisted precipitation method using polyethylene glycol (PEG 6000). The catalysts surface area, crystallinity, reducibility and morphology were characterized by BET, XRD, H2-TPR and SEM-EDS, respectively. The BET analysis indicated that the catalyst calcined at 300 Celsius degrees gave the highest surface area (99.67 m2/g). The crystallite size of Cu in Cu/ZnO/Al2O3 catalyst was estimated to be 14.14 nm., after adding the surfactants. The maximum methanol yield (607.53 CH3OH cat g /Kgcat ) was achieved after 24 hours of residence time using 5 g of the catalyst under a stream of 2 to 1 molar ratio of H2 and CO reactive mixed gas. Under these conditions, 38.26 percent of CO conversion and 93.11 percent of selectivity to methanol were achieved. When the residence time was decreased to 12 hours with molar ratio of 0.5 H2 to 1 CO, the yield of methanol was 388.11 CH3OH cat g /Kgcat, with a CO conversion of 38.53 percent and selectivity to methanol of 90.77 percent.
