Development suggestions for coal to ethylene glycol in domestic

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.
