年初,中科院山西煤炭化学研究所610课题组开发的醋酸加氢合成乙醇技术成功在小店基地完成中试并实现平稳运行,实现了催化剂与工艺的全面验证。这一中试项目规模为50吨/年,采用工业型非贵金属催化剂,醋酸转化率>99.8%,乙醇选择性>99.5%。醋酸加氢合成乙醇是煤经甲醇、醋酸制乙醇技术的核心单元,技术中试的完成,标志着山西 At the beginning of the year, the technology of acetic acid hydrogenation and synthesis of ethanol developed by 610 Task Group of Shanxi Institute of Coal Chemistry of Chinese Academy of Sciences successfully completed the pilot test in the store base and achieved a smooth operation. The comprehensive verification of the catalyst and process was achieved. The scale of the pilot project is 50 tons / year, using industrial non-precious metal catalyst, acetic acid conversion rate> 99.8%, ethanol selectivity> 99.5%. Hydrogenation of acetic acid to ethanol synthesis of coal by methanol, acetic acid ethanol technology core unit, completed in pilot technology, marking the Shanxi
