Title: Dual Nanoparticle/Substrate Control of Catalytic Dehydrogenation

Abstract

Saturated hydrocarbons, or alkanes (C{sub n}H{sub 2n+2}), are abundant in petroleum and can be converted to alkenes (C{sub n}H{sub 2n}) by dehydrogenation. Alkenes, also known as unsaturated hydrocarbons, are easy to polymerize and are the primary feedstock of the petrochemical industry, especially ethene (n=2) and propene (n = 3). Efficient catalytic dehydrogenation is therefore a major industrial objective. It has been found that oxidative catalytic dehydrogenation, that is, a process assisted by both a solid catalyst and a flow of oxygen gas, is most practical because of higher system longevity. Chromia/alumina catalytic systems have been widely adopted by industry. They have also been the subject of scientific studies seeking understanding that may help optimization of the process.
