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 27):
A method of producing olefins, comprising:\n passing methanol and/or dimethylether (DME) into a reaction chamber; wherein the reactor comprises a catalyst that is a crystalline zeotype material in which tetrahedral [TiO 4 ] and [SiO 4 ] units are arranged in a MFI structure with a three-dimensional system of channels having a molecular dimension of 4.9 to 5.9 \u212b, preferably 5.1-5.6 \u212b, and at least 0.5 mass % Ti, more preferably at least 1% Ti, in some embodiments in the range of 1 to 5 mass %Ti; and reacting the methanol and/or DME in the reaction chamber in the presence of the catalyst to make olefins.
