Publication number: 20240052250Abstract: Systems and methods for processing a plastic are disclosed. The system includes a feeding device in fluid communication with a cracking unit. A feed stream comprising a plastic is depolymerized in the feeding device at a depolymerization temperature to produce a hydrocarbonaceous wax stream. The hydrocarbonaceous wax stream is then cracked in the cracking unit. The cracking is conducted at a cracking temperature that is lower than, or the same as the depolymerization temperature.Type: ApplicationFiled: October 26, 2021Publication date: February 15, 2024Applicant: SABIC GLOBAL TECHNOLOGIES B.V.Inventors: Ravichander NARAYANASWAMY, Alexander STANISLAUS, Girish KORIPELLY, Sivakumar PERIYASAMY, Sadasivam GOPALAKRISHNAN, Ranjith PUTHANVEEDU, Anilkumar METTU

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
