摘要

OR (oxidative reforming) of M (methanol) was performed using Cu/ZnO/Al_2O_3-based catalysts, prepared using an oxalic co-precipitation method. We optimized the active catalyst formulation for low reaction temperatures and investigated the effects of varying the steam-methanol mole ratio, the oxygen -methanol mole ratio, WHSV (weight hourly space velocity), precursor mix formulation, reaction temperature, and precipitation temperature, pH, and DTs (drying times) of oxalic acid co-precipitated precursors. The Cu/ZnO/Al_2O_3/Cr_2O_3/CeO_2 (15/15/2.5/1.25/1.25) catalyst provided greater than 80% conversion to methanol at 200 ℃ under CO (carbon monoxide) at 900 ppm, and provided a 100-h lifetime.
