中国科学院山西煤炭化学研究所在“合成气制低碳混合醇新型催化剂及配套工艺技术”方面获得重大进展,完成超过1200h的中试稳定运转。他们在该技术中采用新型铜铁基催化剂,在温度200～260℃,压力4.0～6.0MPa,空速2000～4000h~(-1)的温和反应条件下,CO转化率>80%,高级醇选择性>50%,各项工艺性能指标达到很高水平。本项目中的催化剂替代了贵金属,具有成本低廉、原子
Chinese Academy of Sciences, Shanxi Institute of Coal Chemistry in the “syngas low-carbon mixed alcohol new catalyst and supporting technology” has made significant progress, completed more than 1200h pilot stable operation. They used the new copper-iron-based catalyst in this technology. Under mild reaction conditions of temperature 200 ~ 260 ℃, pressure 4.0 ~ 6.0MPa and space velocity 2000 ~ 4000h ~ (-1), CO conversion> 80%, higher alcohol Selectivity> 50%, the various process performance indicators reached a high level. The catalyst in this project replaces the precious metal, which has low cost and atom
