Study on synergistic mechanism among components of conventional methanol synthesis catalysts based on principle of reverse decoding
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
N

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