(1)合理安排煤制乙二醇项目。目前我国煤制乙二醇技术总体还处于商业化生产前期,尚未完全成熟。国家有关部门也应该统筹兼顾,合理规划,指导发展,大规模推广仍需十分谨慎,以避免企业之间进行盲目新建或扩建装置,导致资源的浪费和无序竞争;(2)加大煤制备乙二醇技术的完善和优化,解决现有合成气羰化加氢生产乙二醇技术的难点和瓶颈,实现现有装置的满负荷运行,酌情开展新的示范;依托大型示范工程,重点解决草酸二甲酯合成反应器 (1) Reasonable arrangement of coal-to-ethylene glycol project. At present, China’s coal-based ethylene glycol technology is still in the early stages of commercial production, not yet fully mature. Relevant departments of the State should also take all factors into consideration, and reasonably planning, guiding development and large-scale promotion still need to be very cautious in order to avoid enterprises blindly constructing or expanding installations that lead to waste of resources and disorderly competition; (2) The improvement and optimization of ethylene glycol technology will solve the difficulties and bottlenecks in the existing ethylene glycol technology for carbonylation and hydrogenation of synthesis gas to realize full operation of existing plants and carry out new demonstration as appropriate. Relying on large-scale demonstration projects, Dimethyl oxalate synthesis reactor
