Patent number: 10751703Abstract: The present disclosure relates to a reforming catalyst and a process for preparing the same. The acidic functionality of the catalyst is suppressed by using a chloride free alumina and coating the chloride free alumina with Group V B metal oxide in the catalyst, which helps in minimizing the cracking reactions and achieving higher selectivity for liquid hydrocarbons and aromatic hydrocarbons.Type: GrantFiled: June 30, 2016Date of Patent: August 25, 2020Assignee: Reliance Industries LimitedInventors: Nagesh Sharma, Veera Venkata Satya Bhaskara Sita Rama Murthy Katravulapalli, Ajay Kumar, Kalpana Gopalakrishnan, Raksh Vir Jasra

Patent number: 10596551Abstract: The present disclosure relates to a reforming catalyst composition comprising a spherical gamma AI2O3 support; at least one Group VB metal oxide sheet coated on to the AI2O3 support; and at least one active metal and at least one promoter metal impregnated on the AI2O3 coated 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.Type: GrantFiled: August 26, 2015Date of Patent: March 24, 2020Assignee: Reliance Industries LimitedInventors: Nagesh Sharma, Ajay Kumar, Veera Venkata Satya Bhaskara Sita Rama Murthy Katravulapalli, Anilkumar Mettu, Kalpana Gopalakrishnan, Raksh Vir Jasra
