Abstract

Normal hexane and normal heptane exhibit a two step desorption profile from silicalite while shorter and longer normal alkanes desorb in a single step. The two step desorption profiles are explained by, and give evidence for, commensurate freezing of the hydrocarbon molecules in the zig-zag channels of silicalite. The freezing results in an additional loss of entropy upon adsorption in silicalite. Also linear alkenes with appropriate chainlength display a two step, but less pronounced, desorption profile. The less pronounced desorption profiles are the result of the lower energetic interaction of the alkenes with the silicalite lattice.
