Adsorption of isopropanol on a nickel catalyst

The adsorption isotherms of isopropanol on a Ni catalyst (15 wt % on SiO2) in the temperature range of 273-303 K are determined. An increase in the isosteric heat of adsorption and entropy of adsorption after treating the catalyst with high frequency plasma in hydrogen and adding 1.5 wt % of Ce is detected, with treatment involving glow discharge plasma in Ar and O2 having virtually no impact on these values. At a low degree of surface filling, the adsorption isotherms are described by the equation of induced adsorption. It is concluded that adsorbed isopropanol molecules are present in two forms: positively and negatively charged. © 2013 Pleiades Publishing, Ltd.
