The kinetics of citral hydrogenation over Pd supported on clinoptilolite rich natural zeolite
The liquid phase hydrogenation of citral has been investigated over Pd (2.42%) supported on clinoptilolite rich natural zeolite catalyst for different reaction conditions. The zeolite support did not affect the active metal ...
Isomerization of α-pinene over ion-exchanged natural zeolites
Catalysts prepared by ion exchange of clinoptilolite-based natural zeolite tuffs with NH4 +, Ba2+ and Pb2+ were investigated in the isomerization reaction of α-pinene at atmospheric pressure under nitrogen flow. Activity ...
Kinetics of proton transfer in the zeolitic tuff
(Central European Science Journals, 2009)
The kinetics of a proton transfer into dilute acid solutions containing natural zeolitic tuff was studied by following the pH evolution of the liquid phase. Four different solutions with tuff contents of 9, 3, 1 and 0.5 ...
A chromatographic study of carbon monoxide adsorption on a clinoptilolite-containing natural zeolitic material
(Taylor & Francis, 2004-11)
In this study, the equilibrium and kinetic parameters for CO adsorption on clinoptilolite-rich natural zeolitic material were determined by the concentration pulse chromatography technique. Experiments were carried out at ...
Silver, zinc, and copper exchange in a Na-clinoptilolite and resulting effect on antibacterial activity
Ag+-Na+, Zn2+-Na+, and Cu2+-Na+ equilibria for clinoptilolite-rich mineral from Gördes (Western Anatolia) were investigated at 25 °C and 0.1 N total solution normality. While silver exchange was favorable over the whole ...
Diffusion mechanism of water vapour in a zeolitic tuff rich in clinoptilolite
The adsorption kinetics of H2O in a clinoptilolite rich zeolitic tuff was experimentally investigated at 18°C. In the identification of the diffusion mechanism the isothermal adsorption model equation was used. It was found ...
