    Abstract: A hydrotreating process with a composition which exhibits high induced magnetism in a small applied magnetic field when formed into a magnetically stabilized fluidized bed and which comprises particles containing a nonferromagnetic component, or components, composited with a plurality of elongated ferromagnetic components, randomly oriented and present in each of said particles in relatively low concentration, based on the total volume of the particles; a process for formation of said compositions and a process wherein such composite particles are formed into a magnetically stabilized fluidized bed and contacted with a fluid, preferably gas.

    Abstract: An adsorption process for the recovery of hydrogen from a feed gas or vapor which contains hydrogen in admixture with one or more hydrocarbon components, alone or in admixture with non-hydrocarbon components. Particulate adsorbent solids are provided with a magnetizable component, or components, and circulated between an adsorption zone in which hydrogen is concentrated in the off gas by contact of the adsorbent solids with the feed, and hydrogen recovered, and a desorption zone in which the exhausted solids are regenerated. Within the adsorption zone the feed is countercurrently contacted with the solids at relatively low temperature to selectively adsorb hydrocarbons, and perhaps other non-hydrogen components. The solids are formed into a moving, fluidized bed, and magnetically stabilized to suppress gross solids circulation while hydrocarbons are adsorbed from the feed. Occluded hydrogen is subsequently displaced from the particulate adsorbent solids with hydrocarbons, and the hydrocarbon enriched particulate adsorbent solids are then transported to the desorption zone. In the desorption zone the solids are fluidized, and the temperature of the bed is elevated sufficiently to desorb at least a portion of the hydrocarbons. The residual hydrocarbons are subsequently displaced, suitably with steam or water by contact with steam in a magnetically stabilized bed of the solids. The wet solids are then dried by contact with hydrogen to displace the water, and cooled to complete the regeneration.
