Abstract

Abstract: In this paper, both volatile and strongly adsorbed products of heavy hydrocarbon conversion on a zeolite were investigated by gas‐phase and solid‐state NMR. For this purpose, the reactions were carried out in sealed glass tubes under vacuum to collect the volatile reaction products. This procedure is demonstrated for pure 2‐ethylphenol conversion on ultra‐stabilized zeolite Y leading to both the formation of light alkanes and deoxygenation products. The above‐mentioned method is useful to improve the understanding of heavy hydrocarbon conversion under batch conditions. Abstract : The conversion of pure 2‐ethylphenol on USY zeolite was investigated by gas‐phase and solid‐state NMR, and formation of light alkanes and deoxygenation of this reactant was found. For this purpose, a method based on sealing of the reactant‐loaded catalyst in a glass tube with an empty volume for collecting the volatile products was developed.
