    摘要: The invention is to a process for removing contaminants from a compressor and/or compressor intercooler in a methanol to olefin separation system. The process comprises compressing an effluent in a compressor having an inlet and an outlet and a compressor surface, the compressing occurring under conditions effective to form a contaminant on the compressor surface. A contaminant-removal medium is injected into the compressor or intercooler and the contaminant-removal medium contacts the contaminant under conditions effective to remove the contaminant from the compressor or intercooler inner surface thereby forming a mobile contaminant. The mobile contaminant is then removed from the compressor or intercooler.

    摘要: A process is described for converting an oxygenate-containing feedstock into one or more olefins in which the feedstock is contacted in a reaction zone with a fluidized bed of a particulate catalyst composition comprising a molecular sieve and at least one metal oxide having an uptake of carbon dioxide at 100° C. of at least 0.03 mg/m2 of the metal oxide whereby at least part of the feedstock is converted into a product stream comprising one or more olefins and a carbonaceous material is deposited on the catalyst composition to produce a coked catalyst composition. The coked catalyst composition is separated from the product stream and divided into at least first and second portions. The first portion of the coked catalyst composition is contacted with a regeneration medium in a regeneration zone under conditions to remove at least part of the carbonaceous material from the coked catalyst composition and produce a regenerated catalyst composition, which is subsequently recycled to the reaction zone. The second portion of the coked catalyst composition is also recycled to the reaction zone but without being initially contacted with a regeneration medium.

    摘要: This invention relates to processes for converting oxygenates to olefins that include a step of pretreating molecular sieve used in the conversion reaction with a C4-C7 olefin composition, which contains one or more C4-C7 olefins. Fresh or regenerated molecular sieve, which is low in carbon content, is contacted or pretreated with the olefin composition to form a hydrocarbon co-catalyst within the pore structure of the molecular sieve, and the pretreated molecular sieve containing the co-catalyst is used to convert oxygenate to a lighter olefin product.
