STABLE SILICOALUMINOPHOSPHATE CATALYSTS FOR CONVERSION OF ALKYL HALIDES TO OLEFINS

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 C2 to C4 olefins. The SAPO...

More Information
Summary: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 C2 to C4 olefins. 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.
