摘要

采用吸附相反应技术(APRT)制备了Cu基催化剂

并用XRD、HRTEM、H2-TPR等表征手段进行了分析。结果表明催化剂中的Cu良好分散于载体表面

粒径在5～10 nm。在液相乙醇体系合成气制甲醇的反应中

该Cu基催化剂对第一步形成中间产物甲酸乙酯的催化活性远高于工业催化剂。APRT制备的催化剂与其他催化剂(包括工业催化剂)在液相合成气制甲醇的两步反应中表现出的显著差异

不仅说明APRT催化剂具有不同的结构特点

也表明甲酸乙酯的形成和进一步的加氢的活性位是不同的。

Abstract

The Cu-based catalysts prepared via adsorption phase reaction technique (APRT) were characterized using XRD

HRTEM and H2-TPR. The results indicated the copper species of catalysts were well-dispersed on the surface of the supports with the size varied from 5—10 nm. In the catalytic methanol synthesis from syngas in ethanol solvent

the prepared catalysts performed a much higher activity than the commercial catalysts did for the formation of intermediate

ethyl formate. The remarkable difference between APRT catalyst and other Cu-based catalyst (including the commercial catalyst) on two reactions of methanol synthesis manifests that the APRT catalyst has a different structure as well as active sites for the formation and hydrogenolysis of ethyl formate.
