Abstract

The H/D exchange between CD4 and OH-groups was studied over zeolite H-ZSM-5, H-mordenite, H-beta and over γ-Al2O3 using the pulsed microcatalytic method. The apparent activation energy of the exchange was found to be independent of the Brönsted acidity of the solid. Results suggested that methane was activated for the reaction by dissociative adsorption over Lewis acid-Lewis base pair sites.
