A process for upgrading a hydrocarbon feed includes passing the hydrocarbon feed and an aromatic bottoms stream to an FCC unit including an FCC reactor and a catalyst regenerator. The hydrocarbon feed is hydrogen-rich having at least 12 wt. % hydrogen, and the aromatic bottoms stream is a bottoms stream produced from an aromatics recovery complex for processing reformate from naphtha reforming. The hydrocarbon feed and aromatic bottoms stream are cracked over the FCC catalysts to produce an effluent and spent FCC catalysts having coke deposits. The spent FCC catalyst is regenerated through combustion of the coke deposits. The hydrogen-rich hydrocarbon feed does not produce enough coke to satisfy the heat demand of the FCC reactor. Cracking the aromatic bottoms stream increases the amount of coke so that combustion of the additional coke during regeneration produces additional heat to satisfy the heat demand of the FCC reactor.

In accordance with one or more embodiments of the present disclosure, a method for producing aromatic compounds from pyrolysis gasoline comprising C.sub.5-C.sub.6 non-aromatic hydrocarbons includes aromatizing the pyrolysis gasoline in an aromatization unit, thereby converting the C.sub.5-C.sub.6 non-aromatic hydrocarbons to a first stream comprising benzene-toluene-xylenes (BTX); hydrotreating the first stream comprising BTX in a selective hydrotreatment unit, thereby producing a de-olefinated stream comprising BTX hydrodealkylating and transalkylating the de-olefinated stream comprising BTX in a hydrodealkylation-transalkylation unit, thereby producing a second stream comprising BTX, the second stream comprising BTX having a greater amount of benzene and xylenes than the first stream comprising BTX; and processing the second stream comprising BTX in an aromatics recovery complex, thereby producing the aromatic compounds from the pyrolysis gasoline, the aromatic compounds comprising benzene, toluene, and xylenes.

A process for producing light olefins comprising thermal cracking. Hydrocracked streams are thermally cracked in a steam cracker to produce light olefins. A pyrolysis gas stream is separated into a light stream and a heavy stream. A light stream is separated into an aromatic naphtha stream and a non-aromatic naphtha stream. The aromatics can be saturated and thermally cracked. The integrated process may be employed to obtain olefin products of high value from a crude stream.

A process for the treatment of a light naphtha feedstock that comprises normal paraffins and iso-paraffins may include separating the feedstock into a first iso-paraffin stream and a normal paraffin stream. The separating may be performed with 5A molecular sieves, a pressure of about 1-3 bars, and a temperature of 100-260° C. A product stream may be provided by subjecting the normal paraffin stream to at least one of steam cracking, isomerizing, and aromatizing.

The present invention provides a method for production of anode grade coke by processing crude oil feed stock in a DCU. The method comprising separation of low boiling light molecular weight components from heavier molecules and processing the same in Delayed Coker Unit after mixing with aromatic rich stream to overcome the operational issue envisaged due to processing of paraffin containing crude feed. The coke so obtained was calcined to produce an improved quality coke having lesser impurities (Sulfur <3 wt %) and better crystallinity.

Processes for using pyrolysis gas as a feedstock or a co-feedstock for making a variety of chemicals, for example, circular ethylene, circular ethylene polymers and copolymers, and other circular products. In these processes, pyrolysis reactor conditions can be selected to increase or optimized the production of pyrolysis gas over pyrolysis oil, and the pyrolysis gas which is usually used as fuel or flared can be fed downstream of the steam cracker furnace for economic use to form circular chemicals. Operating parameters of the pyrolysis unit may be adjusted to increase or decrease the proportion of pyrolysis gas relative to pyrolysis liquid as a function of their relative economic values.
