The present invention relates to a process of increasing syngas production during an upgradation process of petroleum residual oil by circulation of rejuvenated upgrading material through a heat removal zone such as an Auxiliary Reformer and by regeneration of spent upgrading material.


Patent
Indian Oil Corporation Ltd. | Date: 2017-05-10

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.

The present invention relates to delayed coking of heavy petroleum residue producing petroleum coke and lighter hydrocarbon products. The invented process utilize a pre-cracking reactor for mild thermal cracking of the feedstock and an intermediate separator, before being subjected to higher severity thermal cracking in delayed coking process, resulting in reduction in overall coke yield.


The present invention relates to a fluid catalytic cracking additive composition for cracking of heavy hydrocarbon feed stocks and process for preparing the additive. The additive is suitable for enhancing yields of light olefins such as propylene, isobutylene, LPG and reduces the bottom yields. The invention specifically relates to a fluid catalytic cracking additive composition comprising a pentasil zeolite, zeolites having pore size in a range of 5.4-7.7 , alumina, colloidal silica, kaolin clay, and phosphate, wherein the zeolites having pore size in the range of 5.4-7.7 is present in an amount of 1 to 10 wt % with respect to the total amount of the pentasil zeolite and zeolite having the pore size in the range of 5.4-7.7 .


The present invention relates to a Cracking Catalyst composition for cracking of heavy hydrocarbon feed stocks and process for preparing the catalyst. The catalyst is prepared by incorporating 1-10 wt % phosphate treated USY zeolite in which phosphate is present in the range of 10 to 50 wt % on the basis of phosphated zeolite, in a mixture of 10-50 wt % dispersible alumina, 0-30 wt % non-dispersal alumina, 5-30 wt % colloidal silica, 15-50 wt % clay and 5-15 wt % phosphate.

An apparatus for supplying additives into a coker drum includes an inlet for supplying a hydrocarbon feed stream into the coker drum and conduits along the circumference of walls of the coker drum. Each conduit has an injection nozzle to supply additives inside the coker drum. An injection control system controls the operation of the injection nozzles such that 1) one or more of the injection nozzles placed within a first distance above a vapour liquid interphase of the hydrocarbon feed stream are configured to supply the additives; and 2) supply of the additive discontinues from a particular injection nozzle when a distance between the injection nozzle and the vapour liquid interphase is less than or equal to a second distance. The apparatus optionally includes a mechanical drive system moving at least one of the conduits based on the level of the vapour liquid interphase in the coker drum.
