Abstract

The introduction of potassium into a chromia/alumina catalyst has little effect on the dehydrogenation reaction of alkanes to alkenes. However the potassium does have a negative effect on the by-product reactions, hence reducing deactivation. The role of the potassium is to remove acid sites. There is no change in the reaction mechanism.
