    摘要: An improved processing system of an oxygenate-containing feedstock for increased production or yield of light olefins. Such processing involves oxygenate conversion to olefins and subsequent cracking of heavier olefins wherein at least a portion of the products from each of the reactors is elevated in pressure, using a common compressor, prior to being routed to a common product fractionation and recovery section. The system further comprises acid gas removal means to remove acid gases from the cracked product gas and that the olefin cracking reactor is a moving bed reactor.

    摘要: Processes for the conversion of both straight- or branched-chain (e.g., paraffinic) as well as cyclic (e.g., naphthenic) hydrocarbons of a hydrocarbon feedstock into value added product streams are disclosed. The processes involve the use of both dehydrogenation and olefin cracking to produce both light olefins and aromatics in varying proportions depending on the feedstock composition and particular processing scheme. The processes are especially applicable to naphtha feedstocks comprising paraffins and naphthenes in the C5-C11 carbon number range.
