摘　　要：近年来化工产业对乙二醇的需求量不断攀升,而我国乙二醇生产量相对较少,较为依赖国外进口,加大了乙二醇的使用成本。很多专家学者开始研究如何提高乙二醇的产量,而草酸酯法煤制乙二醇的效率较高,主要应用了BGL熔渣气化技术、气体净化工艺与制冷工艺等核心技术。简要分析了草酸酯法煤制乙二醇工艺技术。In recent years,the demand for ethylene glycol in the chemical industry has been rising,while the production of ethylene glycol in China is relatively small,and it is more dependent on foreign imports,increasing the use cost of ethylene glycol.Many experts and scholars began to study how to improve the output of ethylene glycol,and the oxalate method is more efficient in coal to ethylene glycol,mainly using core technologies such as BGL slag gasification technology,gas purification process and refrigeration process.The process technology of coal to ethylene glycol by oxalate ester method is briefly analyzed.
