一种低浓度CO的甲醇制氢催化剂及其制备方法与应用
摘要：
本发明公开了一种低浓度CO的甲醇制氢催化剂及其制备方法与应用，所述的催化剂含有以下质量分数的组分：活性组分10～40%、助剂5～25%、载体35～75%；所述的活性组分包含NiO和Cr2O3；所述助剂为过渡金属氧化物或/和稀土金属氧化物中的一种或多种组合；所述载体包含ZrO2和Al2O3。应用本发明的催化剂进行甲醇重整制氢工艺，产品中只有少量的CO、CO2和CH4等产物，对质子交换膜燃料电池产生影响小，所得到的氢气原料无需提纯即可直接应用于质子交换膜燃料电池，大幅度降低了燃料电池行业用氢的成本。
摘要（英）：

The invention discloses a catalyst for producing hydrogen with low-concentration CO from methanol as well as a preparation method and an application of the catalyst. The catalyst contains components in percentage by mass as follows: 10%-40% of active components, 5%-25% of an aid and 35%-75% of a carrier, wherein the active components comprise NiO and Cr2O3; the aid is one or a combination of moreof transition metal oxide or/and rare earth metal oxide; the carrier contains ZrO2 and Al2O3. The catalyst is applied to a process for producing hydrogen by methanol reforming, the product contains alittle CO, CO2, CH4 and other products, a little influence is produced on a proton exchange membrane fuel cell, obtained hydrogen raw materials can be directly applied to the proton exchange membranefuel cell without purification, and the hydrogen utilization cost in the fuel cell industry is substantially reduced.
