WHB 煤制聚合级乙二醇新技术

摘要

An analysis is made of the industrialization development in production of ethylene glycol from coal currently and problems, details of features of the new technology for producing polymer grade ethylene glycol from coal by using WHB process are given.The exploitation mode of strategic combination of scientific research and engineering has solved the two difficult problems in developing of WHB process, catalyst and engineering, for production of polymerization grade ethylene glycol from coal, the key technical index of the catalyst is in international leading level, and engineering risk is reduced to minimum.The pilot plant products produced by the new technology of manufacturing polymer grade ethylene glycol from coal meet both international high-class product indicators and American polymer grade indicators, results of tests of polymerization, spinning and dyeing and finishing show that all indicators meet or exceed indicators of polyester produced by ethylene glycol by petro-ethylene method, indicating the ethylene glycol can be used in production of polyester.%分析了目前煤制乙二醇工业化的动态与存在的问题，详细介绍了WHB煤制聚合级乙二醇新技术的特点。科研与工程的战略组合开发模式解决了WHB煤制聚合级乙二醇新技术中催化剂与工程化两大难题，催化剂关键技术指标处于国际领先水平，工程化风险降至最低。 WHB煤制聚合级乙二醇新技术中试产品同时达到国标优等品与美国聚合级指标，经聚合、纺丝、染整试验，其全部指标达到甚至有的指标超过石油乙烯法乙二醇制聚酯的结果，表明该乙二醇可以用于聚酯生产。
