| 摘 要： | 研究了Mn改性Cu/ZnO/Al2O3催化剂上的甲醇水蒸气重整制氢反应。考察了催化剂组成、反应温度和水醇比对反应的影响。研究结果表明,当催化剂的组成为Cu45Zn45Al5Mn5,反应温度为220～240℃,n(H2O)/n(CH3OH)=1～1 2,液体空速为3 0h-1左右时,反应具有较好的甲醇转化率、氢气产率和较低的出口CO含量,同时催化剂表现出较好的稳定性。

| Abstract: | The steam reforming of methanol on Mn promoted Cu/ZnO/Al_2O_3 catalysts was studied in this paper. The effects of catalyst composition, reaction temperatures, ratio of water to methanol and feed velocity on steam reforming reaction of methanol were investigated. Under optimized For Cu45Zn45Al5Mn5 catalyst, when reaction temperature was 220-240℃, molar ratio of water to methanol was 1.0-1.2 and liquid space velocity was about 3.0 h~(-1), higher methanol conversion and hydrogen yield and lower outlet CO concentration were obtained, and catalyst showed good stability. |
