Catalyst for preparing 1, 4-butynediol through reaction of formaldehyde and acetylene

The invention discloses a catalyst for preparing 1, 4-butynediol through reaction of formaldehyde and acetylene, and the catalyst comprises the following components in parts by mass: 15-70 parts of copper oxide; 0.5 to 10 parts of bismuth oxide; the invention is suitable for the technical field of catalysts, and provides a catalyst which can solve the problem of ion loss of a catalyst carrier and reduce the content of wastewater, and also has good suspension performance, so that the problem of carrier component loss when an inorganic carrier material is used as an ethynylation catalyst carrier is solved; and the problems that the catalyst is too violently stirred and is easy to wear due to high density of the catalyst in the use process are solved, the operability of the device is improved, and meanwhile, the catalyst has high activity and selectivity. 本发明公开了一种甲醛与乙炔反应制备1,4-丁炔二醇的催化剂，以质量分数计，包括以下组分：15～70份氧化铜；0.5～10份氧化铋；25～80份碳材料载体，本发明适用于催化剂技术领域，提供了一种能够解决催化剂载体离子流失和降低废水含量，同时又具有很好悬浮性能的催化剂，既解决了无机载体材料作为炔化催化剂载体时的载体组分流
