Abstract: 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-%.

Abstract: 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 C5 and C6 hydrocarbons from crude oil processing and a C4 to C5 hydrocarbon stream produced in a steam cracking unit with a catalyst under reaction conditions sufficient to produce an effluent comprising olefins.

Abstract: 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.

Abstract: 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.
