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-%.

Claim (Index 11):
A method for producing ethylene and propylene from catalytic steam cracking of naphtha, the method comprising:\n (a) providing a naphtha feedstock; (b) providing steam; (c) providing a catalyst comprising phosphorus modified mesoporous HZSM-5; (d) feeding the naphtha feedstock and the steam to a reactor comprising the catalyst; and (e) removing an effluent from the reactor, the effluent having a combined yield of ethylene and propylene greater than about 45 percent by weight.
