摘　　要：用煤或天然气代替石油乙烯合成乙二醇技术,是原料路线最科学、资源利用最合理、明显优于石油路线的一项重大C1化学技术.我们在国内外首先全部采用工业原料进行研究和开发,经过20多年的艰苦努力,研究开发成功3个性能优良的催化剂和6部分配套工艺技术,申请了4项国家发明专利,形成中国科学院福建物质结构研究所具有全套自主创新知识产权的新工艺、新技术.经过与江苏丹化科技股份公司的成功合作和共同开发,"用煤代替石油乙烯合成乙二醇"的300吨/年规模中试已经取得成功;万吨级合成乙二醇示范厂已经建成并投入生产;用褐煤年生产20万吨乙二醇工厂也于2007年8月16日在内蒙古通辽露天煤矿开工建设.这些结果标志着这一成套工程技术已进入工业化的实施和应用阶段.这项工艺技术符合我国以煤为主的资源特点和褐煤资源亟待开发利用的实际情况.它是一项真正资源节约型、能源节约型和循环经济产业,在整个生产过程中,三废污染物排放少,符合绿色环保友好工程标准.本技术可以用来生产草酸酯、草酸、乙二醇等重要化工原料,可形成一个很大的新兴产业群并创造巨大的经济效益和社会效益.这项技术的大规模产业化,可以实现我国"用煤或天然气替代石油乙烯合成乙二醇"的战略目标,并将对我国的能源和化工产业产生重大影响.The technique of synthesizing glycol using coal or natural gas to replace petro-ethylene is a major Cl chemical technology that is the most scientific route of raw materials, the most reasonable usage of resources, and thus an obviously more advanced technique than that using petroleum-based raw materials. The research and development were carried out, first in the world, with only industrial raw materials, and for more than 20 years we finally succeeded in obtaining three catalysts with excellent performance and six matching techniques. On the other hand, we have applied for four national patents for inventions and formed a full set of intellectual property rights of independent innovation with new techniques and new technologies by Fujian Institute of Research on the Structure of Matter, Chinese Academy of Sciences. After a successful cooperative research and development with Jiangsu Danyang Chemical Technology Co. Ltd, a middle-scale pilot plant with an annual production capacity of 300 tons for synthetic glycol replacing petro-ethylene by coal has been set up successfully and a 10 000-ton model factory for synthetic glycol has been completed and put into production. A plant of ethylene glycol by using lignite to replace petroethylene is under construction in Tongliao, with a production capacity of 200 000 tons per year. These results demonstrate that the complete sets of engineering and technology have entered the industrialization stage of implementation and application. This technology conforms to China＇s coal-based resource characteristics and the reality that the lignite resources in China are in urgent need of development. This is a real resource-saving and energy-saving technology and recycling economy. At the same time, in the production process, very little waste pollution occurred so it can meet the requirement of environmental protection. This technology can also be used for the production of oxalete ester, oxalic acid, ethylene glycol, oxamide and other important chemical raw materials. A huge ne
