Patent number: 10815432Abstract: The present disclosure relates to an additive and a catalyst composition for a catalytic cracking process of vacuum gas oil for preparing cracked run naphtha having reduced liquid olefin content, and increased propylene and butylene yields in the LPG fraction. The process makes use of a catalyst composition which is a mixture of an FCC equilibrated catalyst and an additive comprising a zeolite, phosphorus and a combination of metal promoters. The process is successful in achieving high propylene and butylene yields in the LPG fraction along with a lower liquid olefin content and increased aromatic content with increase in RON unit in the resultant cracked run naphtha, as compared to that achieved using an FCC equilibrated catalyst alone.Type: GrantFiled: June 1, 2016Date of Patent: October 27, 2020Assignee: Hindustan Petroleum Corporation LimitedInventors: Raman Ravishankar, Sunil Mehla, Somnath Kukade, Peddy Venkata Chalapathi Rao, Nettem Venkateswarlu Choudary

Patent number: 10280372Abstract: The present invention relates to a novel catalyst composition for catalytic cracking of hydrocarbon streams to enhance the yield of light olefins. The catalyst composition for the cracking of hydrocarbon feed streams to light olefins, comprises a USY zeolite with silica/alumina ratio of more than 40, pentasil zeolite, a phosphate compound and alumina silica binder. The yield of olefins is further increased when the catalyst composition is impregnated with a cerium oxide. The present invention also provides a process of increasing the yield of light olefins from hydrocarbon feed streams comprising contacting the hydrocarbon streams with catalyst compositions of the present invention.Type: GrantFiled: January 7, 2014Date of Patent: May 7, 2019Assignee: INDIAN OIL CORPORATION LIMITEDInventors: Biswanath Sarkar, Satyen Kumar Das, Somnath Kukade, Ganga Shankar Mishra, Eswar Prasad Dalai, Velusamy Chidambaram, Sudhir Kumar Pandey, Ram Mohan Thakur, Debasis Bhattacharyya, Santanam Rajagopal

Patent number: 10273417Abstract: An apparatus which is an integral hardware consisting of an annular downer reactor and a concentric upflow riser regenerator for catalytic cracking of hydrocarbon feed to is disclosed. The annular downer reactor terminates in annular stripper which is also concentric with the regenerator. The regenerator, reactor and stripper are in fluid connection with each other. The apparatus is highly compact and provides efficient contact between circulating catalyst and hydrocarbon feed. The proposed hardware includes a novel radial distributor for providing improved control and radial distribution of catalyst inside the downflow reactor. The radial distributor has equal numbers of stationary and movable parts placed one after another to cover the entire annular opening at the bottom of the regenerated catalyst vessel. The radial distributor is concentric with regenerator and located between the catalyst holding vessel and the reactor. A process for catalytic cracking using the invented apparatus is also disclosed.Type: GrantFiled: May 24, 2018Date of Patent: April 30, 2019Assignee: INDIAN OIL CORPORATION LTD.Inventors: Mukthiyar Sadhullah, Satheesh Vetterkunnel Kumaran, Debasis Bhattacharyya, Gadari Saidulu, Somnath Kukade, Brijesh Kumar, Santanam Rajagopal

Patent number: 9573865Abstract: A process for increasing the yield of C3 olefin in fluidized bed catalytic cracking of hydrocarbon feedstocks is disclosed. C4 fraction produced from the cracking of hydrocarbon feedstock in the primary reaction zone (riser), optionally with external source of C4 stream is fed into the stripper which acts as a secondary reaction zone at an elevated temperature and at an optimum WHSV. The elevated temperature is achieved by injecting a part of the regenerated catalyst from regenerator, which is at a higher temperature, directly into the stripper through a dedicated additional lift line. This raises the activity of catalyst inside the stripper. The direct injection of regenerated catalyst into the stripper, besides producing higher yields of propylene, improves the stripping efficiency leading to enhanced recovery of strippable hydrocarbons.Type: GrantFiled: October 11, 2012Date of Patent: February 21, 2017Assignee: INDIAN OIL CORPORATION LTD.Inventors: Manoj Kumar Bhuyan, Debasis Bhattacharyya, Gopinath Bhanuprasad Sayapaneni, Somnath Kukade, Satheesh Kumaran Vetterkunnel
