摘要: A method of preparing a cracking catalyst includes converting one or more clay mineral compositions to metakaolin; synthesizing an intermediate ZSM-5 zeolite from the metakaolin, a silica source, and ZSM-5 zeolite seeds; and forming a cracking catalyst comprising a hierarchical mesoporous ZSM-5 zeolite through disintegration and recrystallization of the intermediate ZSM-5 zeolite. A cracking catalyst for steam enhanced catalytic cracking of hydrocarbons includes a hierarchical mesoporous ZSM-5 zeolite impregnated with manganese, zirconium, or manganese and zirconium, where the cracking catalyst has a mesopore volume of at least 0.30 cubic centimeters per gram (cm3/g). A process for upgrading crude oil through steam enhanced catalytic cracking includes contacting the crude oil with steam in the presence of a cracking catalyst, where the cracking catalyst comprises a hierarchical mesoporous ZSM-5 zeolite impregnated with manganese, zirconium, or both manganese and zirconium.

摘要: Systems and methods for producing light olefins via catalytic cracking of naphtha are disclosed. A naphtha feed stream and lift gas stream are fed into a dense phase riser reactor operated with a high solid volume fraction, a high superficial velocity, minimum back mixing. The effluent stream from the dense phase riser reactor is further separated, in a secondary reactor, to form a gaseous product stream and a catalyst stream. The catalyst stream is stripped to remove the hydrocarbons adsorbed on the catalyst particles. The stripped catalyst is regenerated in a regenerator.

摘要: A process for converting crude oil to light olefins, aromatics, or both, includes contacting a crude oil with an FCC catalyst composition in a catalytic cracking system at a temperature of greater than or equal to 580° C., a weight ratio of the FCC catalyst to the crude oil of from 2:1 to 10:1, and a residence time of from 0.1 seconds to 60 seconds. Contacting causes at least a portion of hydrocarbons in the crude oil to undergo cracking reactions to produce a cracked effluent comprising at least olefins. The FCC catalyst composition for producing olefins and aromatics from crude oil includes ultrastable Y-type zeolite impregnated with lanthanum, ZSM-5 zeolite impregnated with phosphorous, an alumina binder, colloidal silica, and a matrix material comprising Kaolin clay.

摘要: Provided is a composition comprising a blend of a waste plastic and a bio feedstock. Also provided is a process for preparing a stable blend of a plastic and bio feedstock which can be stored or transported if desired. The amount of plastic in the blend comprises no more than 20 wt. % of the blend. The blend can be passed to a conversion unit for conversion of the waste plastic and bio feedstock. The conversion process produces clean monomers for polymerization and chemical intermediates.

摘要: The present disclosure provides molecular sieves with intergrown phases of AEI and CHA topologies and a catalyst thereof. A preparation method for the molecular sieves include the following steps: mixing a hydroxyphosphono organic alkali R with an aluminum source and a silicon source to obtain a sol-gel precursor, putting the sol-gel precursor into a closed hydrothermal synthesis reactor for reaction, filtering the reaction solution, washing, drying, and calcination to obtain the molecular sieves with intergrown phases of AEI and CHA topologies. The molecular sieves and the catalyst thereof can be directly synthesized under mild conditions with a hydroxyphosphono organic alkali as a structure-directing agent and a phosphorus source, have a pH value of 6-9 and low requirements for corrosion resistance of production devices, and are suitable for large-scale production.

摘要: Systems and methods for producing light olefin(s) are disclosed. The method includes contacting a catalyst with a coke precursor to form a light olefin selective catalyst, and contacting the light olefin selective catalyst with a hydrocarbon feed under conditions sufficient to catalytically crack at least a portion of the hydrocarbon feed to form a products stream containing a light olefin, here the light olefin selective catalyst is more selective than the catalyst in catalyzing formation of the light olefin by the catalytic cracking of the hydrocarbon feed.
