Contaminants are removed from a fluid stream 7 in a continuous process by adsorption on fluidized solid adsorbents 3, particularly small particle size adsorbents, which also include a magnetizable component, and are desorbed in a vessel 21 wherein the adsorption and desorption are carried out at substantially the same pressure. The adsorbent particles and magnetizable component 3 flow through the vessels and are stabilized against fluid by-passing and solids back-mixing and recirculation generally associated with fluidized beds (except for the flow or movement of the solids through the contacting vessels) during adsorption and desorption by the use of magnetic fields (applied by means 5 and 5a). Numerous adsorption processes are exemplied including the removal of acid gases or other polar materials from gas streams, e.g. from combustible or refinery gases, and the separation of hydrocarbon mixtures. <IMAGE> |
