The present invention relates to a process for production of high yield of hydrogen by carrying out the dry reforming of the dry gas generated from the process itself by utilizing the same catalyst for cracking and producing high yield of light olefins such as ethylene, propylene and butylenes from residue feedstocks.

Process for producing hydrogen and light olefins from resid fluid catalytic cracking

A process for conversion of hydrocarbon feedstock into lighter olefins of Cto Ccarbons, the process comprising of cracking the hydrocarbon feedstock in a reactor in the presence of a catalyst. The catalyst for short contact time catalytic cracking process of heavy hydrocarbons having contact time less than 1 second to produce light olefins of Cto Ccarbon in the range of 40 to 60 wt % on fresh feed basis in a fluidized bed reactor which is concentric downflow reactor in presence of catalyst consisting of ultra-stable Y zeolite in the range of 5-10 wt %, 4 to 8 wt % of pentasil zeolite, 2.5-5 wt % of bottom selective material, 0.5-2 wt % of rare earth and 75-88 wt % of support material.

Production of high yields of light olefins from heavy hydrocarbons

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.

Process for production of high quality syngas through regeneration of coked upgradation agent

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.

Production of high yield of syngas through regeneration of coked upgrading agent

Present invention relates to a novel process for upgrading a residual hydrocarbon oil feedstock having a significant amount of Conradson Carbon Residue (concarbon), metals, especially vanadium and nickel, asphaltenes, sulfur impurities and nitrogen to a lighter more valuable hydrocarbon products by reducing or minimizing coke formation and by injecting fine droplets of oil soluble organo-metallic compounds at multiple elevations of the riser with varying dosing rates.

Process of upgradation of residual oil feedstock

A two stage Fluid Catalytic Cracking process and an apparatus for simultaneous production of light olefins such as ethylene and propylene and middle distillate range hydrocarbons, wherein a first flow reactor, preferably a downer and a second flow reactor, preferably a riser are operating at varying reaction severities using different catalyst systems with the regenerated catalyst entering the reactors inlet through independent regenerators. Mild cracking of the fresh feedstock is carried out in the first flow reactor of short residence time and the effluent of first flow reactor is separated in an intermediate separator/fractionator followed by re-cracking of the C4 hydrocarbons and naphtha range hydrocarbons, preferably C5-150&#xb0; C. from the second product separation section and unconverted hydrocarbons (370&#xb0; C.+) of first flow reactor, in the second flow reactor at higher severity employing different catalyst system.
