Abstract
Official abstract text for this publication.
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 μm to 200 μm, which results in formation of reformed products of naphtha and ethylbenzene formed in-situ.
First claim
Opening claim text (preview).
The invention claimed is: 1. A naphtha reforming process for obtaining reformed naphtha comprising contacting naphtha with a catalyst, said 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 μm to 200 μm, which results in formation of reformed products of naphtha and ethylbenzene formed in-situ. 2. The naphtha reforming process as claimed in claim 1 , wherein said in-situ ethylbenzene is dealkylated into benzene (C 6 ) and/or toluene (C 7 ). 3. The naphtha reforming process as claimed in claim 1 , wherein the ethylbenzene formed in the reformed products is in the range of 3.6 wt % to 4.75 wt % of the mass of the reformed products. 4. The naphtha reforming process as claimed in claim 1 , wherein the ethylbenzene formed in the reformed products is in the range of 4.68% to 4.75% of the mass of the reformed products.
