Abstract
Based on data of n-butane conversion over HZSM5, different transition states are proposed for the Bronsted acid catalyzed reactions of alkan es involving carbonium ions as intermediates. Hydrogen-deuterium excha nge, dehydrogenation and cracking are proposed to proceed via pentacoo rdinated carbonium ions that are stabilized by the zeolite lattice.
