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 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.

Process for catalytically converting naphtha to light olefins

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.

Process for converting naphtha to light olefins with separation

A de-hydrogenation catalyst and its use in dehydrogenation of hydrocarbons. The catalyst has low cracking activity and comprises gallium or gallium and platinum on an essentially non-acidic and amorphous alumina-phosphate or silica-alumina-phosphate support with an empirical chemical composition of [Al2O3][SiO2][P2O5], wherein Y is between 0 and 0.2 and Z is between 0.01 and 1.1, with a BET surface area above 50 m/g, as measured by N2 adsorption experiment.

Catalyst for propane dehydrogenation to propylene

An improved MFI zeolite having low aluminum occupation at intersection sites characterized by an ortho-xylene to para-xylene uptake ratio of 0.1 to about 0.55. Processes for converting hydrocarbon or oxygenate to a product comprising light olefins and/or aromatics using the improved MFI zeolite as catalyst are also disclosed. Para-xylene in the product may be greater than about 24% of the xylenes.
