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.

Abstract: 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.

Abstract: 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]Y[P2O5]Z, wherein Y is between 0 and 0.2 and Z is between 0.01 and 1.1, with a BET surface area above 50 m2/g, as measured by N2 adsorption experiment.
