Abstract

The invention relates to a catalyst for deeply removing CO at low temperature as well as the preparation and activation methods and the application thereof. The catalyst is the CuO-ZnO-ZrO2 composite catalyst which comprises 50-90wt% of CuO, 5-40wt% of ZnO and 5-40wt% of ZrO2. The copper-containing component has the reduction degree of 70-80%, and the reduction degree is represented by the ratio of the weight of the metallic copper to the total weight of the metallic copper and the copper oxide calculated according to the CuO. Compared with the prior art, the catalyst is used for removing the CO in the liquid or gaseous hydrocarbon and / or inert gas and has the characteristics of high activity at low temperature of 0-50 DEG C, high removal depth of 20ppb or lower and long service life. The process for preparing the catalyst is simple, and the cost spent in preparing the catalyst can be lowered.

Description

technical field

[0001] The invention relates to a catalyst for removing CO from hydrocarbon or inert gas materials, its preparation method, activation method and application. The invention is especially suitable for the removal of trace amounts of CO in α-olefins and saturated hydrocarbons in the field of petrochemical industry, or the preparation of high-purity gases (such as nitrogen, helium, argon, etc.) in the electronic industry. Background technique

[0002] In various industrial fields, the presence of trace carbon monoxide is often harmful to the reaction system and needs to be removed as an impurity. With the development of polyolefin technology, highly active polyolefin catalysts are very sensitive to poisons, and polyolefin raw materials are required to be "polymerization grade" olefins. Specifically, the carbon monoxide impurity in olefin raw materials does not exceed 30ppb. Typical is the propylene polymerization process. With the development of propylene polym...
