Abstract
The present disclosure relates to a process for converting one or more methyl halides to acyclic C3-C6 olefins, said process comprising the steps of (a) providing a feedstream comprising one or more methyl halides; (b) providing a catalyst composition; and (c) contacting said feedstream with said catalyst composition under reaction conditions. The process is remarkable in that said reaction conditions include a reaction temperature below 400° C., and in that said catalyst composition comprises one or more molecular sieves with a Si/Al atomic ratio ranging from 2 to 18 and wherein said one or more molecular sieves comprise a plurality of pores, wherein said pores have a shape of an 8-membered ring or less.
