“…[19][20][21][22][23] In this route, methyl acetate (MA) is rstly synthesized by the DME carbonylation reaction, which is an important intermediate reaction, and then EtOH is prepared by MA hydrogenation. The zeolites used in the DME carbonylation reaction chiey include mordenite (MOR), 19,[24][25][26][27][28][29][30][31] ferrierite (FER, ZSM-35), 8,[19][20][21][22][32][33][34][35][36][37][38][39][40][41][42][43][44][45] and some novel zeolites (EU-12, 46 SSZ-13, 47 HSUZ-4, 48,49 Al-RUB-41, 50 and T 51 ). Among them, MOR has the highest DME conversion and MA selectivity, but it suffers from severe deactivation owing to the presence of larger 12-membered ring (12-MR) channels.…”
