研制开发了一种耐ＣＯ低温高效四组分（Ｃｕ－Ｃｒ－Ｍｎ－Ｎｉ）改进铜铬催化剂，其原料合成气中ＣＯ允许含量可高达１３Ｖ％；在常压，４１３Ｋ，原料气Ｈ２／ＭＦ＝４／１（ｖ／ｖ），流速为１８００ｍＬ／ｈｇｃａｔａｌ．的反应条件下，ＭＦ转化率高达９９．８％，甲醇选择性为９９．９％（在相同反应条件下二组分的Ｃｕ－Ｃｒ催化剂上ＭＦ转化率仅为７３．１％，甲醇选择性为９８．０％），当向原料气中添加１３．１Ｖ％ＣＯ时，ＭＦ转化率仍可以稳定达到９５．９％，甲醇选择性为９６．３％．实验结果表明，ＣＯ导致催化剂失活的重要原因之一是ＣＯ导致Ｃｕ＋深度还原为Ｃｕ０，减少催化剂的活性中心
An improved Cu-Cr-Mn-Ni modified Cu-Cr catalyst has been developed. The allowable content of CO in raw syngas can be as high as 13V%. At atmospheric pressure, 413K, feed gas H2 / MF = 4/1 (v / v) at a flow rate of 1800 mL / hgcatal. , The conversion of MF was up to 99.8% and the selectivity of methanol was 99.9% (MF conversion was only 73.1% on the two-component Cu-Cr catalyst under the same reaction conditions. The selectivity to methanol 98.0%). When 13.1V% CO was added to the feed gas, the MF conversion was still 95.9% and the methanol selectivity was 96.3%. The experimental results show that one of the important reasons for the catalyst deactivation caused by CO is that CO leads to the reduction of Cu + depth to Cu0 and reduces the active center of the catalyst
