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.

Light olefins yield improvement over light olefin selective catalyst

The presently disclosed subject matter relates to methods of producing ethylene and propylene by the catalytic steam cracking of naphtha using an HZSM-5 catalyst. An example method can include providing a naphtha feedstock, providing steam, and providing an HZSM-5 catalyst. The method can further include preparing the HZSM-5 catalyst by titanium modification or alkaline treatment, followed by phosphorus modification. The method can further include feeding the naphtha feedstock and steam to a reactor containing the catalyst and removing an effluent from the reactor having a combined yield of ethylene and propylene of greater than about 45 wt-%.

Methods for producing ethylene and propylene from naphtha

Systems and methods for the catalytic cracking of light hydrocarbons, such as naphtha, to form light olefins and aromatics is disclosed. The systems and methods may include a catalytic cracking process that involves mixing catalyst with a gas and then this mixture is used to contact a hydrocarbon feed, e.g., light straight run naphtha or heavy straight run naphtha. The hydrocarbon feed may be mixed with dry gas such as methane and/or hydrogen to dilute the hydrocarbon feed, before the hydrocarbon feed is contacted with the catalyst/gas mixture.

Process integration for cracking light paraffinic hydrocarbons

Processes to produce olefins from a hydrocarbons stream obtained from a catalytic cracking unit are described. The process includes the integration of metathesis of Colefin process and a hydrocarbon catalytically cracking process to produce commercially valuable products (for example, Colefins and a Cgasoline hydrocarbons).

Process to produce olefins from a catalytically cracked hydrocarbons stream

A method that integrates a catalytic cracking process with a crude oil conversion to chemicals process is disclosed. The method may include contacting, in a catalytic cracking reactor, a mixture of the hydrocarbon stream comprising primarily Cand Chydrocarbons from crude oil processing and a Cto Chydrocarbon stream produced in a steam cracking unit with a catalyst under reaction conditions sufficient to produce an effluent comprising olefins.

Integration of catalytic cracking process with crude conversion to chemicals process

The invention pertains to a zeolite catalyst, methods of making same, and its use in the catalytic cracking of naphtha for the production of lower molecular weight olefins and alkanes, while minimizing production less desirable products. A zeolite is modified by base leaching and by the addition of a metal cation, thereby lowering the Si/Alratio and improving the stability of the formed catalyst.

Modified zeolite catalyst and methods for producing and using same

The inventions described herein relate to catalysts comprising a zeolite comprising at least one metal or ion thereof, wherein the at least one metal or ion thereof comprises barium, strontium, titanium, tungsten, or a mixture thereof, and wherein the zeolite does not comprise molybdenum, or phosphorus, and methods related thereto.
