Discussion on the reduction in methanol consumption in DMTO-Ⅱ
Thread Content
This post was last edited by jordan569 on 2013-1-6 at 21:08. According to available information, the DMTO-Ⅱ process reduces the methanol consumption per ton of olefins from 2.96 tons in the DMTO process to 2.68 tons; meanwhile, the olefin yield increases by 12%. The selectivity of DMTO is 78.7% for ethylene/propylene (39.8% for ethylene and 38.9% for propylene), while the selectivity of DMTO-Ⅱ for ethylene/propylene is 85%-90%. Could someone tell me the exact distribution of ethylene and propylene as products? Is the reduction in methanol consumption mainly due to the C4+ recycling technology, which improves the selectivity of ethylene/propylene, or is there some other reason? Note: # ) # # .
Let me show you an official website; specifically, it deals with the reprocessing of by-products from the first-generation technology to produce propylene: http://www.syn.ac.cn/news/jszq/2011/7/117201251217317.html http://www.syn.ac.cn/news/jszq/2011/7/11781539381150.html
Thank you, Floor 2; I now know where to find out more about the cutting-edge aspects of MTO technology! :)
