    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: An ion exchange method is provided for loading and uniformly distributing noble metals into a catalyst substrate comprising a zeolite to make a monofunctional, non-acidic reforming catalyst. The catalyst substrate is contacted with an aqueous loading solution comprising noble metal cations and non-noble metal cations. The loading solution is formulated such that the equivalents of non-noble metal cations remaining in the catalyst not ionically bonded to the zeolite when loading is complete is 1.2 to 6.0 times the equivalents of non-noble metal cations displaced from the zeolite when the noble metal cations ion exchange into the zeolite, and simultaneously the endpoint pH of the loading solution is between 10.0 and 11.5. The required 1.2 to 6.0 ratio is achieved when the ratio of moles of non-noble metal cations added to the loading solution to moles of noble metal added to the loading solution is between 1 and 10. The use of ion exchange method results in zeolite catalysts having reduced amounts of detrital material in the micropores of the zeolite.
