heal.abstract	The measurement of local (homogeneous) adsorption energies εi, local monolayer capacities, Cmax*, local adsorption isotherms, θ(p, T, ε), and probability density functions for adsorption, f(ε) and φ(ε; t), can be used to study the mechanism of adsorption of five gaseous hydrocarbons on the heterogeneous surface of magnesium oxide. The method does not use analytical or numerical solutions of a classical integral equation comprising f(ε) as unknown, but it depends on a time function of gas chromatographic peaks obtained by short flow-reversals of the carrier gas. The results for adsorption of ethane, ethylene, acetylene, propene, and 1-butene on MgO, in the absence and presence of O3 are given and discussed on the basis of a mechanism proposed earlier for argon on titatium dioxide.	en
