PROCÉDÉ DE MODIFICATION D'UN CATALYSEUR HÉTÉROGÈNE À L'AIDE D'UN COMPOSÉ ORGANOMÉTALLIQUE, CATALYSEUR HÉTÉROGÈNE ET UTILISATION DU CATALYSEUR POUR EMPECHER LA FORMATION DE COKE

摘要

A process and system for modifying heterogeneous catalysts by contacting them with chemical compounds to functionalize the surface of the heterogeneous catalyst. A polymetallic catalyst including bimetallic catalyst is functionalized on its surface by employing a precursor of an inorganic compound. The precursor of the inorganic compound is an organometallic compound, and the metal based inorganic compound is aluminum oxide. A process and system for surface modification functionalization of the heterogeneous catalysts at conditions including room temperature and atmospheric pressure.
