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.
