    摘要: The present disclosure relates to a process for converting methyl halides to C3-C5 α-olefins, said process comprising the steps of (a) providing a feedstream comprising methyl halides; (b) providing a first and second catalyst composition, said second catalyst composition comprising a metathesis catalyst; (c) contacting said feedstream with said first catalyst composition in a first reaction zone under first reaction conditions to provide a first product stream, and (d) contacting said first product stream with an olefin stream and with said second catalyst composition in a second reaction zone under second reaction conditions to provide a second product steam. The process is remarkable in that said step (c) is performed under 400°C, and in that said first catalyst composition comprises molecular sieves with a Si/Al atomic ratio between 2 and 18 and with a plurality of pores with a shape of an 8-membered ring or less.

    摘要: A cost-effective and energy-efficient process is disclosed for converting a methane-containing gas to a methane sulfonyl halide comprising reacting the methane-containing gas, under illumination by a light emitting diode (LED) source, with a sulfuryl halide or a halogen in the presence of sulfur dioxide, whereby the methane sulfonyl halide is obtained for isolation or further reactions. The further reactions may sequentially include, in order, contacting the methane sulfonyl halide with a catalyst complex to form a methane monohalide; catalytically converting the methane monohalide to a value-added chemical such as an alcohol, an olefin, an aromatic, derivatives thereof, or mixtures thereof; releasing any hydrogen halide formed in the process; and converting the hydrogen halide to a halogen and recycling it for re-use.

    摘要: Processes and systems for recovering bromine. A process may comprise contacting a gas stream comprising bromine with a liquid bromide stream comprising bromide anions to produce at least an off-gas stream that is substantially bromine free and a liquid stream comprising bromine anionic complexes; and heating at least a portion of the liquid stream to produce at least bromine from at least a portion of the bromine anionic complexes.
