Adsorption and activation of ethene by zeolite-H-ZSM-5

摘要: Thermogravimetric adsorption data for C2H4 and H2O i.r. n.m.r. spectroscopic results are combined to obtain information on the role played by acidic Bronsted sites in H-ZSM-5 zeolite activation of C2H4. Water ethene compete such various ways which depend pretreatment zeolite. Physisorbed water prevents Ethene is readily activated reacts sites, even at room temperature. There further evidence formation carbenium-type intermediates.
