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,催化剂EP1能够满足现有的以天然气为原料的合成氨低变工艺和宽温变换流程。
以Cu-Zn-Al繫催化劑為主，添加稀土製備寬溫變換催化劑，攷察瞭稀土的添加量、操作溫度和催化劑彊度對催化劑活性的影響。結果錶明,催化劑EP1能夠滿足現有的以天然氣為原料的閤成氨低變工藝和寬溫變換流程。

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.
