Disclosed is a method for converting an alkyl halide to an olefin. The method includes contacting a silicoaluminophosphate (SAPO) catalyst with a feed that includes an alkyl halide under reaction conditions sufficient to produce an olefin hydrocarbon product that includes Cto Colefins. The SAPO catalyst has bimodal acidity designated as weak acid sites and strong acid sites. The weak acid concentration is less than 0.55 mmol/g-cat and the total acid concentration is less than 1.5 mmol/g-cat.

Stable silicoaluminophosphate catalysts for conversion of alkyl halides to olefins

Methods for preparing bound non-acidic germanium zeolite catalysts are disclosed, where the preparation is reproducible and scalable and where the catalysts have similar or the same activity and selectivities of a standard naphtha aromatization catalyst and methods for aromatizing naphtha.

Catalyst for light naphtha aromatization

A catalyst and its preparation and use are disclosed. The catalyst is a silicalite having germanium (Ge) included within the framework of the silicalite prepared in a particular manner. The catalyst may be used in a method of converting hydrocarbons wherein a hydrocarbon feed is contacted with the catalyst. The catalyst may be formed by preparing an aqueous reaction mixture of a silica-containing silicalite precursor material and a germanium source. The reactants of the reaction mixture are allowed to react. The reacted reaction mixture is heated under conditions to form crystals of a silicalite having germanium included within the framework of the silicalite. The crystals are then calcined to form the catalyst. In certain embodiments, a noble metal may be deposited upon the germanium-containing silicalite.
