The present disclosure relates to a reforming catalyst composition comprising a spherical gamma AIOsupport; at least one Group VB metal oxide sheet coated on to the AIOsupport; and at least one active metal and at least one promoter metal impregnated on the AIOcoated support. The reforming catalyst composition of the present disclosure has improved activity, better selectivity for total aromatics during naphtha reforming and results in less coke formation. The reforming catalyst composition has improved catalyst performance with simultaneous modification of acidic sites as well as metallic sites through metal support interaction. The acid site cracking activity of the catalyst is inhibited because of the use of chloride free alumina support modified with solid acid such as Group VB metal oxide and impregnated with active metals. The present disclosure provides a process for naphtha reforming in the presence of the reforming catalyst composition of the present disclosure to obtain reformates of naphtha.

Reforming catalyst and a method of preparation thereof

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.

Modified heterogeneous catalyst

The present disclosure relates to a process for preparing a catalyst. The process comprises coating zeolite gel over the alumina support to obtain a chloride free zeolite gel coated alumina support, crystallizing the chloride free zeolite gel coated alumina support, washing, drying and calcining the crystallized zeolite coated alumina support to obtain a calcined crystallized chloride free zeolite coated alumina support, treating the calcined crystallized chloride free zeolite coated alumina support with ammonium nitrate to obtain sodium free support, washing, drying, and calcining the support to obtain a calcined chloride free zeolite coated alumina support, immersing the calcined chloride free zeolite coated alumina support in an active metal and a promoter metal solution mixture followed by stirring to obtain a metal coated chloride free zeolite coated alumina support, and drying and calcining the metal coated chloride free zeolite coated alumina support to obtain the catalyst.

Process for preparing a catalyst

The present disclosure relates to a naphtha reforming process for obtaining reformed naphtha comprising contacting naphtha with a catalyst, the catalyst comprising a chloride free zeolite coated alumina support impregnated with 0.01 wt % to 0.5 wt % active metal and 0.01 wt % to 0.5 wt % promoter metal, wherein the thickness of the zeolite coating on the alumina support ranges from 100 &#x3bc;m to 200 &#x3bc;m, which results in formation of reformed products of naphtha and ethylbenzene formed in-situ.
