Use of Clinoptilolite in Ethanol Dehydration [PDF]
Separation 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 ...

Autoignition of Ethanol-Diesel Blends: Is it Worth Dehydrating Ethanol?
SSRN Electronic Journal, 2021 This study analyses the impact of the concentration of water in ethanol on the autoignition characteristics of ethanol-diesel blends. A constant volume combustion chamber was used to emulate the conditions of a diesel engine. Tests were carried out modifying the water content in the alcohol, and then the concentration of hydrated ethanol in the diesel ...
