METHODS FOR UPGRADING HYDROCARBON FEEDS TO PRODUCE OLEFINS
The present disclosure is directed to methods for upgrading a hydrocarbon feed that may include separating the hydrocarbon feed to produce at least a greater boiling point effluent and a lesser boiling point effluent. The greater boiling point effluent may have an American Petroleum Institute gravity less than 30 degrees. The method may further include contacting the greater boiling point effluent with a multicomponent catalyst, which may cause at least a portion of the greater boiling point effluent to undergo catalytic cracking and produce a first spent multicomponent catalyst and a first cracked effluent comprising one or more olefins. The multicomponent catalyst may include from 0 weight percent to 10 weight percent ZSM-5, from 10 weight percent to 40 weight percent zeolite Beta, and from 10 weight percent to 30 weight percent USY zeolite based on the total weight of the multicomponent catalyst.
PROCESS FOR PRODUCTION OF NEEDLE COKE
High-quality graphite/needle grade coke is produced with reduced impurity levels and improved coefficient of thermal expansion using an integrated hydrotreatment, catalytic cracking and coking reaction sections, employing a combination of highly paraffinic hydrotreated VGO stream and aromatic CLO stream, which is thereafter processed in a delayed coking section.
INTEGRATED PROCESS FOR CONVERSION OF WHOLE CRUDE TO LIGHT OLEFINS
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.

The invention also includes a process for the catalytic cracking of feedstock comprising contacting the feedstock under catalytic cracking conditions with a FCC catalyst and the metal trapping additive.
Process and apparatus for producing lower carbon olefins and BTX by catalytic pyrolysis of hydrocarbon-containing feedstock oil
A process includes: cutting a hydrocarbon-containing feedstock oil into a light distillate oil and a heavy distillate oil; introducing the light distillate oil and a first catalyst into a down-flow reactor to produce a stream; subjecting the stream to a gas-solid separation to produce a first reaction hydrocarbon product and a first spent catalyst; or, introducing the stream into a fluidized bed reactor, and then subjecting to a gas-solid separation to produce a second reaction hydrocarbon product and a second spent catalyst; introducing a continuous catalyst, the heavy distillate oil and a second catalyst into an up-flow reactor, and then subjecting to a gas-solid separation to produce a third reaction hydrocarbon product and a third spent catalyst; separating out lower carbon olefins and light aromatics from reaction hydrocarbon products, separating out a light olefin fraction, and returning the light olefin fraction to the fluidized bed reactor or the up-flow reactor.

METHOD AND SYSTEM FOR TREATING HYDROCARBON-CONTAINING MIXTURE
A method for processing a hydrocarbon-containing mixture includes the steps of: I) separating the hydrocarbon-containing mixture into a light fraction and a heavy fraction; II) reacting the light fraction from step I) in an aromatization unit and separating the resulting reaction product into a C.sub.5.sup.− component and a C.sub.6.sup.+ component; III) reacting the heavy fraction from step I) and optionally the C.sub.6.sup.+ component from step II) in an aromatics conversion unit and separating the resulting reaction product into a C.sub.5.sup.− component, a C.sub.6-C.sub.7 component, a C.sub.8 component, and a C.sub.9.sup.+ component; and IV) optionally, steam cracking or catalytic cracking one or both of the C.sub.5.sup.− component from step II) and the C.sub.5.sup.− component from step III). The method can convert low-value hydrocarbon mixtures into C.sub.8 aromatic hydrocarbons and cracking raw materials, and improve the product value.

A METHOD FOR THE PRODUCTION OF DIESEL
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.
