摘要: Abstract (POM) Partial oxidation of methanol over a Pt/Al2O3 catalyst with low Pt content is studied where the influences (GHSV) gas hourly space velocity and oxygen-to-methanol molar ratio (O2/C) on formation, reaction temperature, and conversion are evaluated. POM operations under cold start preheating also examined. The results indicate that an increase in GHSV significantly lowers performance. Nevertheless, 50% consumed when as high 20,000 h−1. maximum H2 CO concentrations located at O2/C = 0.7, yielding optimum O2/C for POM. Compared to operation, bed 150 °C obviously intensifies performance, 100% achieved O2/C ≥ 0.6. This reveals can be used trigger production. combination Cu/ZnO/Al2O3 triggering followed by steam reforming investigated. temperature two-stage lower than alone, but production former improved. improvement especially pronounced GHSVs.
