Adsorption Equilibria -- Pure gas isotherms

Abstract

The adsorption equilibria for eight of the lower hydrocarbons frommethane to C4's were measured for silica gel and several activatedadsorption carbons. Most of the data were obtained at 25\,^{\circ}C.and at pressures up to 1 atmosphere. In addition, in several casesthe effect of temperature was investigated up to approximately 250\,^{\circ}C.and pressures up to 20 atmospheres were studied. The adsorption isothermswere correlated by a modification of the Polanyi adsorption potentialtheory.
