Abstract:
Methods of simultaneously converting butanes and methanol to olefins over Ti-containing zeolite catalysts are described. The exothermicity of the alcohols to olefins reaction is matched by endothermicity of dehydrogenation reaction of butane(s) to light olefins resulting in a thermo-neutral process. The Ti-containing zeolites provide excellent selectivity to light olefins as well as exceptionally high hydrothermal stability. The coupled reaction may advantageously be conducted in a staged reactor with methanol/DME conversion zones alternating with zones for butane(s) dehydrogenation. The resulting light olefins can then be reacted with iso-butane to produce high-octane alkylate. The net result is a highly efficient and low cost method for converting methanol and butanes to alkylate.

Claim (Index 30):
A staged reactor system for the synthesis of light olefins, comprising:\n a reactor comprising plural alternating first and second zones in a series of at least two first zones alternating with at least two second zones; and a flow path through the series of plural alternating first and second zones; wherein the first zone comprises a first catalyst and an inlet for methanol or DME; wherein the first catalyst comprises a crystalline Si/Ti zeotype material of the type described herein for the conversion of DME to olefins; wherein the second zone comprises a dehydrogenation or cracking second catalyst; wherein the first and second catalysts are different.
