A fluid catalytic cracking catalyst composition (FCC catalyst composition) includes a framework-substituted ultra-stable Y-type zeolite (USY zeolite) having one or more transition metals substituted into the framework of a USY zeolite and a FCC zeolite cracking additive. A method for upgrading a hydrocarbon feed includes contacting the hydrocarbon feed with the FCC catalyst composition of the present disclosure at reaction conditions sufficient to upgrade at least a portion of the hydrocarbon feed. A method for upgrading a hydrocarbon feed includes passing the hydrocarbon feed to a fluid catalytic cracking unit, contacting the hydrocarbon feed with a FCC catalyst composition in the fluid catalytic cracking unit under reaction conditions sufficient to cause at least a portion of the hydrocarbon feed to undergo cracking reactions to produce a cracking reaction mixture comprising a used FCC catalyst composition and a cracked effluent comprising one or more olefins.

FCC catalyst compositions for fluid catalytic cracking and methods of using the FCC catalyst compositions

The invention relates to a method for optimizing layered catalytic processes. This is accomplished by testing various catalysts with a compound found in a feedstock to be tested, to determine the facility of the catalyst in hydrogenating, hydrosulfurizing, or hydrodenitrogenating the molecule, and hence the feedstock. In a preferred embodiment, the Double Bond Equivalence of the feedstock and molecule are determined, and catalysts are pre-selected based upon their known ability to work with materials of this DBE value. In preferred embodiments, the layered catalysts include a demetallization catalyst, used before hydrocracking. In additional preferred embodiments, the test feedstock contains 500 ppmw or less asphaltenes, preferably C-asphaltenes.

The present invention relates to a hydrocracking catalyst for hydrocarbon oil comprising a support containing a framework-substituted zeolite-1 in which zirconium atoms and/or hafnium atoms form a part of a framework of an ultrastable y-type zeolite and a hydrogenative metal component carried thereon and a method for producing the same. The hydrocracking catalyst of the present invention makes it easy to diffuse heavy hydrocarbon oils such as VGO, DAO and the like into mesopores, is improved in a cracking activity and makes it possible to obtain a middle distillate at a high yield as compared with catalysts prepared by using zeolite comprising titanium and/or zirconium carried thereon.

In a hydrocracking process, the product from the first stage reactor passes through a steam stripper to remove hydrogen, HS, NH, light gases (C-C), naphtha and diesel products. The stripper bottoms are separated from hydrogen, HS, NH, light gases (C-C), naphtha, and diesel products and treated in a second stage reactor. The effluent stream from the second stage reactor, along with the stream of separated hydrogen, HS, NH, light gases (C-C), naphtha, and diesel products, are passed to a separation stage for separating petroleum fractions. Preferably, the effluent stream from the first stage reactor is passed through a steam generator prior to the steam stripping step. In an alternate embodiment, the effluent stream from the first stage reactor is passed through a vapor/liquid separator stripper vessel prior to the steam stripping step.

The invention relates to a method for optimizing layered catalytic processes. This is accomplished by testing various catalysts with a compound found in a feedstock to be tested, to determine the facility of the catalyst in hydrogenating, hydrosulfurizing, or hydrodenitrogenating the molecule, and hence the feedstock. In a preferred embodiment, the Double Bond Equivalence of the feedstock and molecule are determined, and catalysts are pre-selected based upon their known ability to work with materials of this DBE value.

A process for removing iron impurities, inter alia iron or iron compounds, from petroleum oil distillation residues is disclosed in which a high gradient magnetic separator incorporates a pack of ferromagnetic fillers in the form of a generally flat or curved sheet-like strip. The ferromagnetic filler is a Fe--Cr alloy of a selected composition and the strip is of selected geometric characteristics such that the rate of removal of iron impurities can be maintained substantially at a maximum throughout the separation mode of operation prior to and after washing of the ferromagnetic filler.
