摘　　要：本文考察了焙烧温度、还原温度、反应温度、反应压力和体积空速对用于ＣＯ２加氢反应的超细ＣｕＯ／ＺｎＯ／ＳｉＯ２催化剂性能和产物分布的影响，确定了催化剂的合适焙烧温度、还原温度。Effects of pre treatment conditions(calcination and reduction temperatures) and reaction conditions (temperature,pressure and space velocity)on the product pattern and the catalytic performance of ultrafine CuO/ZnO/SiO 2 catalysts for methanol synthesis from carbon dioxide and hydrogen were studied.The suitable calcination and reduction temperatures were 773K and 623K respectively , and the hydrogenation of carbon dioxide were carried out at 528K,5000h -1 and high pressure.The results indicated that carbon dioxide was more easily hydrogenated than carbon monoxide.
