The adsorption of butene-1 on Beta zeolite (H form) is studied via flow-adsorption calorimetry. Upon feeding a mixture of 2 vol % of butene-1 in nitrogen over the pre-calcined zeolite (500掳C) at room temperature, an exothermic effect is observed that is associated with the adsorption ...
The thermodynamic surface properties and Lewis acid-base constants of H-beta-zeolite supported rhodium catalysts were determined by using the inverse gas chromatography technique at infinite dilution. The effect of the temperature and the rhodium percentage supported by zeolite on the acid base ...
The catalytic etherification of glycerol has been systematically studied in batch process by using n-butanol to produce oxygenated additives for biodiesel fuels over various solid-acid catalysts, such as H-beta zeolite, ZSM-5, K10, etc.. The present work includes a detailed study of the ...

The reaction mechanism of alkylation of benzene with propylene to produce cumene over H-beta zeolite was investigated by density functional theory (DFT) using a 5T cluster model at the B3LYP/6-31G* level. The Mulliken population analysis was conducted to investigate the charge transfer analysis. ...
This paper studied the esterification of acetic acid with isopentyl alchol, using modified HBeta zeolite as catalyst. Reaction parameters were discussed. The acidity of catalyst was also characterized. The results show that the conversion of acetic acid can be up to 98% under the reaction conditio...
