Abstract
A process for converting naphtha to light olefins comprises contacting a naphtha stream with a zeolitic catalyst to produce a light paraffin stream at conditions which dehydrogenate the naphtha to olefins, interconvert the olefins to lighter olefins and hydrogenate the lighter olefins to produce a light paraffin stream comprising ethane and propane. The catalyst may comprise a zeolite and a metal.
Claims21
A process for converting naphtha comprising:
- contacting a naphtha stream with a zeolitic catalyst at conditions which dehydrogenate paraffins to olefins, interconvert the olefins to lighter olefins and hydrogenate the lighter olefin to produce a light paraffin stream comprising ethane and propane.
A process for converting naphtha comprising contacting a naphtha stream with a zeolitic catalyst with more metal on the binder than on the zeolite at conditions which dehydrogenate paraffins to olefins, interconvert the olefins to lighter olefins and hydrogenate the lighter olefin to produce a light paraffin stream comprising ethane and propane.
A process for converting naphtha to ethane and propane comprising:
- contacting a naphtha stream with a catalyst comprising MFI zeolite with a Si/Al2 molar ratio of from about 20 to about 500 and/or an AEL molecular sieve and a metal on a binder at conditions which dehydrogenate the paraffins to olefins and naphthene to aromatics, interconvert the olefins to lighter olefins and hydrogenate the lighter olefins to produce a light paraffin stream comprising ethane, propane and aromatics.
