含稀土宽温变换催化剂的研制

Development of a wide temperature shift catalyst with rare earth promoter

以Cu Zn Al系催化剂为主 ,添加稀土制备宽温变换催化剂 ,考察了稀土的添加量、操作温度和催化剂强度对催化剂活性的影响。结果表明 。

A new type wide temperature shift catalyst has been prepared by adding rare earth metal to a Cu Zn Al system catalyst.The effects of adding amount of rare earth metal,reaction temperature and catalyst strength on catalyst activity were surveyed.It demonstrated that the catalyst EPI can fit the low temperature shift process and the wide temperature shift process in synthesis ammonia with natural gas as feedstock.
