According to one more embodiments, presently disclosed are processes for producing petrochemical products from a hydrocarbon material. The process may include separating the hydrocarbon material into at least a lesser boiling point fraction and a greater boiling point fraction, combining steam with the greater boiling point fraction upstream of the cracking of the greater boiling point fraction, cracking at least a portion of the greater boiling point fraction in the presence of a first catalyst to produce a first cracking reaction product, combining steam with the lesser boiling point fraction upstream of the cracking of the lesser boiling point fraction, cracking at least a portion of the lesser boiling point fraction in the presence of a second catalyst to produce a second cracking reaction product, and separating the petrochemical products from one or both of the first cracking reaction product or the second cracking reaction product.

Light olefins may be produced from a hydrocarbon feed by a method that includes separating the hydrocarbon feed into at least a light gas fraction stream comprising C.sub.1-C.sub.4 alkanes, a light fraction stream comprising C.sub.5+ alkanes, and a heavy fraction stream. The temperature cut between the light fraction stream and the heavy fraction stream may be at 280° C. to 320° C. The method may further include steam cracking at least a portion of the light gas fraction stream to produce a steam cracked effluent stream and catalytically cracking at least a portion of the light fraction stream and the heavy fraction stream in a steam enhanced catalytic cracker (SECC) to produce a catalytically cracked effluent stream. The steam cracked effluent stream and the catalytically cracked effluent stream may be sent to a product separator to produce the light olefins.

A feed stream including crude oil may be processed by a method that includes separating the feed stream into at least a C.sub.1 hydrocarbon fraction, a C.sub.2-C.sub.4 hydrocarbon fraction, and a C.sub.5+ hydrocarbon fraction. The method may further include methane cracking at least a portion of the C.sub.1 hydrocarbon fraction to form a methane cracked product, steam cracking at least a portion of the C.sub.2-C.sub.4 hydrocarbon fraction to form a steam cracked product, and steam enhanced catalytically cracking at least a portion of the C.sub.5+ hydrocarbon fraction to form a steam enhanced catalytically cracked product. The method may further include passing at least a portion of the steam cracked product and at least a portion of the steam enhanced catalytically cracked product to a product separator to produce one or more product streams. Systems for processing a feed stream comprising crude oil are further described herein.

A method for preparing feed material for a catalytic depolymerisation process, the method comprising the steps of: separating feedstock into two or more feedstock streams based on one or more properties of the feedstock, introducing each of the two or more feedstock streams into one or more process vessels, processing the feedstock streams in the presence of a catalyst in the process vessels under conditions of elevated temperature in order to produce two or more intermediate feedstock streams, and blending the two or more intermediate feedstock streams to form the feed material.

The invention relates to a process configuration for production of light olefins and aromatics from residual hydrocarbon streams. In this configuration a high severity catalytic cracking process is employed for producing higher yields of lighter olefins and various boiling fractions. C4 stream separated from gaseous product is subjected to metathesis and aromatized to form mono aromatics.

Embodiments of the disclosure provide a system and method for producing light olefins from a crude oil. A crude oil feed is introduced to a crude distillation unit to produce a distillate fraction and a residue fraction. The distillate fraction is introduced to a non-catalytic steam cracker to produce a light olefin fraction and a pyrolysis oil fraction. The residue fraction is introduced to a supercritical water reactor to produce an effluent stream. The effluent stream is introduced to a flash separator to produce a gas phase fraction and a liquid phase fraction. The gas phase fraction is introduced to a catalytic steam cracker to produce a light olefin fraction and a pyrolysis oil fraction. Optionally, the residue fraction is introduced to a vacuum distillation unit to produce a light vacuum gasoil fraction, a heavy vacuum gasoil fraction, and a vacuum residue fraction. The vacuum residue fraction is introduced to a solvent deasphalting unit to produce a deasphalted oil and a pitch fraction. The deasphalted oil fraction, optionally combined with the heavy vacuum gasoil fraction, can be introduced to the supercritical water reactor in lieu of the residue fraction.

Systems and methods for processing full range naphtha and producing light olefins and BTX are disclosed. Full range naphtha is separated in naphtha splitter to produce a light naphtha stream and a heavy naphtha stream. The heavy naphtha stream is then fed to a heavy naphtha catalytic cracker to produce a cracked stream. The effluent from the steam cracking unit and the effluent from the catalytic cracking unit may be flowed into an oil quench tower and are further separated in a separation unit to produce purified ethylene, propylene, butadiene, 1-butene, and BTX. The cracked stream maybe further processed. The light naphtha stream or both the lights stream combined with the light naphtha stream is fed to a steam cracker to produce an effluent stream comprising olefins. Effluent of the steam cracker is fed to the processing unit to separate light olefins. The C.sub.6+ hydrocarbons from the processes may be recycled.

The invention relates to C.sub.5+ hydrocarbon conversion. More particularly, the invention relates to separating a vapor phase product and a liquid phase product from a heated mixture that includes steam and C.sub.5+ hydrocarbons, catalytically cracking the liquid phase product and steam cracking the vapor phase product.

Processes for producing olefins include integration of steam cracking with a dual catalyst metathesis process. The processes include steam cracking a hydrocarbon feed to form a cracking reaction effluent containing butenes, separating the cracking reaction effluent to produce a cracking C4 effluent including normal butenes, isobutene, and 1,3-butadiene, subjecting the cracking C4 effluent to selective hydrogenation to convert 1,3-butadiene in the cracking C4 effluent to normal butenes, removing isobutene from a hydrogenation effluent to produce a metathesis feed containing normal butenes, and contacting the metathesis feed with a metathesis catalyst and a cracking catalyst directly downstream of the metathesis catalyst to produce a metathesis reaction effluent. Contacting with the metathesis catalyst causes metathesis of normal butenes to produce ethylene, propene, and C5+ olefins, and contacting with the cracking catalyst causes C5+ olefins produced through metathesis to undergo cracking reactions to produce additional propene, ethylene, or both.
