Abstract
Process for the preparation of an olefinic product, which process comprises contacting a reaction mixture comprising an oxygenate feedstock and an olefinic component with an oxygenate conversion catalyst comprising a molecular sieve having one-dimensional 10-membered ring channels, in a flow-through reactor unit defining a flow trajectory for fluids towards a downstream outlet for an olefinic reaction effluent from the flow-through reactor unit, wherein an olefinic co-feed is added at an upstream olefin feed inlet of the flow-through reactor unit, and wherein oxygenate feedstock is admitted to the reactor such that it is added to the reaction mixture at a plurality of locations along the feed trajectory.
