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 29):
A method of making C2-C6 olefins from methanol and/or DME, comprising:\n passing a stream of methanol and/or DME over a catalyst in a reaction chamber; wherein the catalyst comprises a crystalline zeotype material comprising: a system of channels having a pore limiting diameter of 4.9-6.2 \u212bA, at least 0.5 wt % Ti and a Si/Ti ratio of at least 5; and having high hydrothermal stability as exhibited by test conditions in which the catalyst is exposed to 1.0 1/hr DME at 475\u00b0 C. for 8 hours at which point DME conversion remains at 100% with an olefin selectivity greater than 85%) or having high hydrothermal stability such that, after steaming the catalyst at 600\u00b0 C. for 3 hours in 1 atmosphere steam, the catalyst exhibits less than 10% loss in surface area as measured using the Brunauer\u2014Emmett\u2014Teller (BET) method, controlling conditions in the reaction channel so that the temperature in the reaction chamber is in the range of 300 to 600\u00b0 C.; wherein at least 90 wt % of the methanol and/or DME is converted to products in the reaction channel to form a product stream; and collecting the product stream which comprises at least 70 mol % C2-C6 olefins; and wherein the selectivity to C2-C6 olefins decreases by less than 10% over a period of at least 8 hours of continuous operation without regenerating the catalyst.
