The experimental study on the source and scathe of the poison sulfur, iron and nickel in methanol catalyst has measured by physical-chemical instruments and chemical analytical methods.

The researches of the optimization of preparation process of methanol catalyst were summarized,also including the increase of catalyst activity and stability by adding the fourth component to the Cu/Zn/AI catalysts,the influence of impurityies on the catalyst properties,as well as the poisoning mechanism,the grain size and the hole structure control of the catalysts,The study on pre-reduction ca.

The formation mechanism of iron and nickel carbonyl and their influences on the methanol catalyst are reviewed in detail in this paper.

The selection of shift process in industrial produc tion of methanol was discussed, the effecting factors causing the poisoning & loss of activity for methanol catalyst were analyzed from the aspects of chlorine & chloride, metal carbonyl, trace of ammoinia and oil contaminant etc, the appropriate solvable methods were presented.

Research situation of synthesis methanol catalyst abroad & at home was introduced;the research & development progress of new type of foreign metal catalysts was described for zinc-chromium catalyst,copper base catalyst and alloy catalyst etc.
