Abstract: The present disclosure relates to a process and system for modifying heterogeneous catalysts by contacting them with chemical compounds. Specifically, the present disclosure relates to an easy and convenient process for surface functionalizing of a heterogeneous catalyst such as polymetallic catalyst including bimetallic catalyst by employing precursor of inorganic compound, wherein the precursor is organometallic compound and wherein the inorganic compound includes but is not limited to a metal based inorganic compound such as aluminium oxide. The present disclosure thus provides for easy and convenient process and system for surface modification/functionalization of heterogeneous catalysts by employing precursor of inorganic compound at conditions including but not limiting to room temperature and atmospheric pressure.

Abstract: The present disclosure relates to a composition, wherein the composition is a catalyst comprising support matrix, active metal, promoter metal and halide, wherein the support matrix is additionally subjected to a modifier to obtain a modified support matrix. The catalyst in the reaction reduces the percentage coke formation and provides for an enhanced reformate yield having an increase total aromatic yield and C8 aromatic yield when compared to the known/commercially available catalyst for naphtha reforming process, and also improves the quality of reformate obtained at end of the reaction. The disclosure further relates to process of preparation of the catalyst, the catalyst of the present disclosure derived from the process described, displays lower deactivation during the reaction demonstrating increased stability and reduction in the regeneration frequency and thereby making the catalyst economically feasible.
