A process for converting naphtha to predominantly ethane comprising contacting a naphtha stream with a zeolitic catalyst comprising a noble metal and hydrogen to produce a light paraffin stream comprising ethane and propane; wherein the catalyst comprises at least about 0.005 wt % noble metal at a ratio of hydrogen to hydrocarbon of less than about 5. In a predominantly propane mode, the catalyst comprises about 0.005 wt % noble metal and operates at a reaction temperature of no more than about 450° C. The process can be switched between modes depending on the desires of the operator.

Process for catalytically converting naphtha to light olefins with predominant modes

A process for oligomerizing and oligomerizing olefins to distillate fuels which regenerates a first stage oligomerization catalyst bed and/or a second oligomerization catalyst bed in situ by contact with an oxygen gas at elevated temperature. The oligomerization catalyst can be restored to full activity. A regeneration process can enable continuous operation.

Process for converting olefins to distillate fuels with regeneration

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.

A family of crystalline aluminosilicate zeolites has been synthesized that is a layered pentasil zeolite. These zeolites are represented by the empirical formula:MRAlESiOwhere M is an alkali, alkaline earth, or rare earth metal such as sodium or strontium, R can be a mixture of organoammonium cations and E is a framework element such as gallium, iron, boron, or indium. These zeolites are characterized by unique x-ray diffraction patterns and compositions and have catalytic properties for carrying out various hydrocarbon conversion processes.

High surface area pentasil zeolite and process for making same

A process for converting naphtha to light olefins comprises contacting a naphtha stream with a zeolitic catalyst to produce a light paraffin stream. The light paraffin may be separated into an ethane stream and a propane stream. The ethane in the ethane stream may be converted into ethylene, and the propane in the propane in the propane stream may be converted into propylene. The light paraffin stream may also be separated into a heavy stream which may be recycled back to the contacting step.
