- W2364263433 abstract "The synthesis of ethyl tertiary butyl ether (ETBE) from isobutene and ethanol has been investigated on different zeolite catalysts at temperatures from 45 to 90 ℃ and pressures from 1 3 to 1 8 MPa. The Hβ zeolite was found to be as active as the A 35 resin catalyst, and be noticeably superior to HMCM 22, HZSM 5 and HY. The activity of the zeolites followed the sequence: HβHMCM 22HZSM 5HY. Compared with the A 35 resin catalyst, the Hβ zeolite is less sensitive to the ethanol/isobutene ratio, and has better selectivity for ETBE. Bonding agents, such as pseudoboehmite, can decrease the catalytic activity of zeolite Hβ, while pore making agents, such as polyethylene glycol, can increase the activity of the bonded Hβ zeolite catalyst. The catalyst sample with 5% polyethylene glycol 4000 as pore making agent even had higher activity than the A 35 resin catalyst at temperatures higher than 65 ℃." @default.
