    摘要: Process for the preparation of an olefinic product, which process comprises reacting an oxygenate feedstock and an olefinic co-feed in a reactor in the presence of an oxygenate conversion catalyst comprising a molecular sieve having one-dimensional 10-membered ring channels, and a further molecular sieve having more-dimensional channels, wherein the weight ratio between the one-dimensional molecular sieve and the further molecular sieve is in the range of from 1:1 to 100:1, to prepare an olefinic reaction effluent; separating the olefinic reaction effluent into at least a first olefinic fraction and a second olefinic fraction; recycling at least part of the second olefinic fraction; and recovering at least part of the first olefinic fraction as olefinic product.

    摘要: Process for the preparation of olefins comprising reacting an oxygenate and/or olefinic feed in a reactor in the presence of a molecular sieve catalyst to form a mixture which comprises olefins and at least partially coked catalyst; passing at least partially coked catalyst to a regenerator; introducing into the regenerator an oxygen-containing gas to regenerate the at least partially coked catalyst, thereby producing a gaseous mixture and at least partially regenerated catalyst; separating at least partially regenerated catalyst and at least part of the gaseous mixture; analysing the composition of the gaseous mixture to control the burning rate of the coke present on the at least partially coked catalyst in the regenerator by adjusting the mass flow rate of the oxygen-containing gas on the basis of the analysis of the gaseous mixture; and passing at least part of the at least partially regenerated catalyst back to the reactor.
