Publication number: 20210154635Abstract: The present disclosure relates to circulating fluidized bed apparatuses for dehydrogenation of alkanes to alkenes with higher yield and selectivity. The apparatus includes a riser-type reactor, a separator section, a regenerator and a withdrawal well disposed downstream to the regenerator. The apparatus includes a transfer line to receive hot regenerated catalyst free of oxygen from the withdrawal well, and to pre-treat the catalyst with a reducing gas to regulate-oxidation state of metals on the catalyst before reintroducing the catalyst to the riser-type reactor. The transfer line is formed in an elongated U-shaped pipe such that the oxidation state of the metals on the catalyst is regulated by the time the pre-treated catalyst reaches the bottom of the riser-type reactor.Type: ApplicationFiled: September 28, 2020Publication date: May 27, 2021Applicant: INDIAN OIL CORPORATION LIMITEDInventors: Hima Bindu DOOSA, Ram Mohan THAKUR, Vineeth Venu NATH, Sadhullah MUKTHIYAR, Madhusudan SAU, Debasis BHATTACHARYYA, Gurpreet Singh KAPUR, Sankara Sri Venkata RAMAKUMAR

Patent number: 10526202Abstract: The present invention relates to a process for the production of high quality synthesis gas rich in hydrogen during the process of upgrading the residual hydrocarbon oil feedstock by rejuvenating the spent upgrading material in Reformer in absence of air/oxygen without supplying external heat source other than the heat generated inside the process during combustion of residual coke deposited on the upgrading material. The present invention further relates to the apparatus used for preparation of syngas wherein said syngas thus produced is used for production of hydrogen gas. Furthermore, the present invention also provides system and method for preparing pure hydrogen from syngas.Type: GrantFiled: August 18, 2016Date of Patent: January 7, 2020Assignee: Indian Oil Corporation LimitedInventors: Sadhullah Mukthiyar, Sayapaneni Gopinath Bhanuprasad, Gadari Saidulu, Eswar Prasad Dalai, Sanjeev Singh, Satheesh Vetterkunnel Kumaran, Debasis Bhattacharyya, Brijesh Kumar, Biswapriya Das
