Ethylene Formation from Ethanol Dehydration Using ZSM‑5 Catalyst [PDF]

open access: yesACS Omega, 2017
Catalysts prepared for ethanol dehydration in a fixed-bed reactor acted as strong active acidic catalysts under reaction conditions at lower temperatures. Experimental conditions including the catalyst type [active aluminum oxide (γ-Al2O3) and ZSM-5 zeolite catalyst modified using two-stage through dealumination or desilication and by using the ...

Use of Clinoptilolite in Ethanol Dehydration [PDF]

open access: bronzeSeparation Science and Technology, 1996
Clinoptilolite-type natural zeolite, which exists in various regions of Turkey, has been experimentally studied. For the ethanol-water-local clinoptilolite system, uptake and breakthrough curves were determined under a nitrogen gas atmosphere. In adsorption kinetics and adsorption equilibrium studies, the effects of particle size, temperature and ...
