Embodiment 1

[0060] Catalysts were prepared using a co-current method.

[0061] Mix 716mL of 1 mol / liter copper nitrate solution and 24.3mL 1 mol / liter zirconium oxychloride solution evenly, then add the mixed solution and 1000mL 1 mol / liter sodium carbonate solution in parallel to a 2L container for For precipitation, the precipitation temperature is 90°C, and the pH value is controlled at 10.5±0.5. Then it was aged for 2 hours under vigorous stirring, and the aging temperature was 90°C. It was then filtered and washed at least six times with deionized water at 80 °C until Na 2 The O content is less than 0.05%. Dry at 110°C for 12 hours, and bake at 400°C for 6 hours. Made with 95% CuO and 5% ZrO 2 CuO / ZrO 2 Catalyst, marked 1 # catalyst. According to BET analysis, the specific surface area is 15m 2 / g.

Abstract

The invention discloses a bi-component copper-zirconium catalyst for deeply removing CO, belongs to the technical field of impurity removal, and provides the bi-component copper-zirconium catalyst inorder to solve the problems of insufficient depth for removing the CO, high CO removing temperature, short service life and the like in the prior art. The bi-component copper-zirconium catalyst comprises 0.1 to 99.9 weight percent of main component CuO and 0.1 to 99.9 weight percent of second component ZrO2; the ZrO2 exists in a morphous form; and the XRD analysis shows that the grain diameter ofthe catalyst CuO is between 1 and 30nm and the specific surface is between 1 and 300m<2>/g. The catalyst can deeply remove the micro CO in various materials to below 30ppb at a reaction temperature ofbetween 0 and 150DEG C.

Description

technical field [0001] The present invention relates to a catalyst for removing impurities and its preparation method and application, more specifically, the present invention relates to a catalyst for removing carbon monoxide and its preparation method and application. 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. In the electronics industry, especially in the manufacture of semiconductor components, "electronically pure" high-purity gases are required, and the carbon monoxide impurity contained is required to be less than several ppb. With the development of polyolefin technology, highly active polyolefin catalysts (such as metallocene catalysts, etc.) are very sensitive to poisons, and polyolefin raw materials are required to be "polymerization grade" olefins. Specifically, carbon monoxide impurities in olefin raw materials do not exceed 30pp...
