Effect Factors on Methanol Reforming over ZnO/Cr2O3/CeO2/ZrO2 Monolithic Catalyst
【摘要】 在ZnO／Cr2O3／CeO2／ZrO2整体催化剂上考察了各种工艺条件对甲醇自热重整制氢过程的影响。对正交实验的方差分析表明:对甲醇的转化率、氢产率和产物中CO选择性影响显著程度为反应温度>空速>水醇摩尔比>氧醇摩尔比。该催化剂合适的反应温度为440-460℃, 空速400 h-1,氧醇比0．15-0．20,水醇比约1．0。
【Abstract】 Effects of different process conditions on methanol autothermal reforming over ZnO/Cr2O3/CeO2/ ZrO2 monolithic catalyst were investigated. Orthogonal experiments show that the reaction temperature has the greatest effect on the conversion of methanol, the yield! of hydrogen and the CO selectivity in product. The space velocity comes next and the water/methanol molar ratio is the third, whereas oxygen/methanol mo lar ratio is the last. The suitable reaction temperature for catalyst is 440 - 460 ℃, the space velocity is 400 h-1, the osygen/methanol molar ratio is 0.15 - 0.20 and the water/methanol molar ratio is 1.0.
