The greenhouse effect of carbon dioxide (CO2) has been recognized as one of the most serious problems in the world. Conversion of CO2 to methyl alcohol (CH3OH) was studied using catalytic chemical methods. Honeycomb-typed monolith used as catalyst support was 400 cell/inch2. Pretreatment of the monolith surface was carried out by thermal treatment and acid treatment. Monolith-supported nanosized CuO-ZnO catalysts were prepared by wash-coat method. The prepared catalysts were characterized by using SEM, TEM, and XRD. The catalytic activity for CO2 hydrogenation to CH3OH was investigated using a flow-type reactor with varying reaction temperature, reaction pressure and contact time. Conversion of CO2 was increased with increasing reaction temperature, but selectivity to CH3OH was decreased. Optimum reaction temperature was about 250 degrees C under 20 atm. Because of the reverse water gas shift reaction.
二氧化碳（CO₂）的温室效应已被公认为全球最严重的问题之一。人们利用催化化学方法研究了将CO₂转化为甲醇（CH₃OH）的过程。用作催化剂载体的蜂窝型整料为400目/英寸²。通过热处理和酸处理对整料表面进行预处理。采用浸渍法制备了整料负载的纳米CuO-ZnO催化剂。利用扫描电子显微镜（SEM）、透射电子显微镜（TEM）和X射线衍射（XRD）对制备的催化剂进行了表征。使用流动型反应器，在不同的反应温度、反应压力和接触时间下，研究了CO₂加氢制CH₃OH的催化活性。随着反应温度的升高，CO₂的转化率增加，但对CH₃OH的选择性降低。在20个大气压下，最佳反应温度约为250℃。这是由于逆水煤气变换反应。
