MUMBAI, India, Oct. 5 -- Intellectual Property India has published a patent application (202521031731 A) filed by Indian Oil Corporation Limited on March 31, 2025, for A Fluid Catalytic Cracking Process For Conversion Of Crude Oil To Light Olefins And Aromatics.
Inventors include Nath, Vineeth Venu; Pati, Saiprasad; Singh, Shakti; Sadhulla, Mukthiyar; Terapalli Hari Venkatadevi, Prasad; Gadari, Saidulu; Kumar, Sarvesh; Pulikottil, Alex Cheru; and Sharma, Alok.
The application for the patent was published on October 02, 2026, under issue no. 40/2026.
Abstract: The present invention relates to a process involving high severity catalytic cracking to convert whole crude oil to light olefins and aromatics, and a dual catalytic cracking reactor system in which two reactors are connected in a series with respect to the catalyst flow. The process enables the refiner to maximize the production of value-added petrochemical feedstock and minimize the production of liquid fuel directly from crude oil using a single process unit. The reactor system comprises a fractionator (A), a dense fluidized bed reactor (B), an Upflow reactor cum Stripper (C), a product separation section (E) and a combustor (D).
