摘要

煤炭气化制备甲醇是重要的清洁能源化工技术，能降低碳排放、减少环境污染，但合成气制甲醇对催化剂的催化活性和热稳定性要求高，如何定向优化催化剂性能是该方向的研究热点。以MC17商业催化剂为基础，采用共沉淀法制备了三元、二元及纯相模型催化剂，通过XRD、N

吸/脱附等分析其物化性质，通过改变催化剂铜锌比（

(CuO):

(ZnO)），探究了催化剂反应机理与构效关系，并考察了Al对催化剂的调控作用。结果表明，铜锌比可影响催化剂结构和催化活性，适宜的铜锌比为3:1~2:1，此时催化剂的CO转化率达67.2%，模拟失活后活性保留率在86%以上。优化铜锌比并引入Al能有效提升甲醇合成催化剂催化的活性与热稳定性，为甲醇合成催化剂的设计与优化提供了参考依据。

Abstract

The preparation of methanol from coal gasification is an important clean energy chemical technology

which can reduce carbon emission and environmental pollution

but methanol from syngas requires high catalyst activity and thermal stability

and targeted optimization of catalyst performance is a research hotspot in this direction. Based on MC17 commercial catalyst

ternary

binary and pure-phase model catalysts were prepared by co-precipitation method. The physicochemical properties were analyzed by XRD

adsorption/desorption and so on. The reaction mechanism and structure-activity relationship of the catalyst were investigated by changing the copper-zinc ratio (

(CuO):

(ZnO)) of the catalyst

and the regulation of Al on the catalyst was investigated. The results show that the copper-zinc ratio can affect the structure and catalytic activity

of the catalyst. The appropriate copper-zinc ratio is 3:1 to 2:1. CO conversion rate of the catalysts reaches 67.2%

and the retention of activity after simulated deactivation is above 86%. The optimization of the copper-zinc ratio and the introduction of aluminium can effectively improve the activity and stability of the methanol synthesis catalysts

which provides a reference for the design and optimization of methanol synthesis catalysts.
