摘要
作为自然界中含有丰富碳源的CO_2,经过催化加氢制含氧化合物的研究,近年来为人们所关注,特别是CO_2加氢制甲醇.从CO_2出发制含氧化合物其前景是诱人的,则可利用碳和氧得到化学品,二则减少了自然界中的CO_2含量,有益于环境保护.本文对Cu-Zn系和Rh-V系催化剂进行初步考察.
The one step production of oxygenate from CO2 + H2 over Cu-Zn and Rh-V catalysts have been studied. The effects of carrier and promoter and operating parameters on the reactivity and selectivity have been investigated. The results show that for the Cu-Zn/SiO2 catalyst, CH3OH constitutes 80% of the products; for the Cu-Zn-Z(Y) catalyst, 50% of the products is CH3OCH3; while for the Rh-V/ SiO2 catalyst, 25% of the products is C2H5OH.
