为了合理利用煤炭,降低煤制乙二醇风险,提高乙二醇产量,介绍了间接法制乙二醇工艺流程。详细分析了国内煤制乙二醇工业化进展。统计分析了国内拟建及在建的煤制乙二醇项目。发现煤制乙二醇项目存在催化剂缺少长周期、大规模运行经验,产品质量不稳定,单套反应器生产能力小,产业链过短等技术及市场风险。最后以某煤制乙二醇项目为例,通过成本、收益等的计算,发现当原料煤与燃料煤的单价均为450元/ t 时,煤制乙二醇的成本为5403.62元/ t,传统的石油制乙二醇成本为6300元/ t,因此煤制乙二醇更具有推广前景。

In order to make rational use of coal and reduce the risk of coal to ethylene glycol,meanwhile,increase the ethylene glycol yield, this paper introduced the technological process of ethylene glycol synthesis by indirect method and its industrialization first,then analyzed the proposed and under construction coal to ethylene glycol projects at home.There were technological and market risk.At present,there were no catalysts having long-period and stable operation instance,the products quality varied,the productivity of reactor was low and the industry chain was short.Taking one coal to ethylene glycol project as research object,the cost and benefits were calculated.If both of per ton of feed coal and fuel coal was RMB 450,then the cost of coal to ethylene glycol and traditional oil to ethylene glycol was RMB 5403.62 and 6300 per ton.So the coal to ethylene glycol had good prospect.
