摘要： The invention includes process and apparatus for removing pollutants from a gas including fluidizing a bed of particles in a container, introducing a gas containing pollutant into the bed, removing the pollutant through deposition on the particles, controlling temperatures in the container by injecting coolant fluid through a coolant nozzle, and reducing clogging or fouling on the coolant nozzle. The process and apparatus includes controlling temperatures in the container within narrowly specified ranges of temperatures and providing a constant pressure of coolant fluid and constant pressure of purge gas to the coolant nozzle such that interchangeable selection made between the coolant fluid and purge gas in a time period sufficiently short provides accurate temperature control and reduces clogging or fouling on the coolant nozzle.

摘要： A method is described for effecting the removal of alkali metal contaminants from a super heated gaseous mixture useful in power generation. Finely divided refractory oxide particles are introduced into the hot gaseous mixture without effecting a substantial reduction in the temperature and operating efficiency of the system. The alkali metal contaminants are substantially removed from the hot gaseous mixture by being adsorbed onto the surface of the finely divided refractory oxide particles.

摘要： 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 hydrocarbon, 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 by contact with stream in a magnetically stabilized bed of the solids. The wet solids are then dried by contact with hydrogen to displace the water, or steam, and then cooled to complete the regeneration.

摘要： In the scrubbing of gases containing sorbable contaminants, particularly the waste gases from reduction cells for electrolytic production of aluminium the waste gas is injected tangentially into the bottom of a cylindrical chamber, from which it is withdrawn through an axial outlet passage at the top end. A solid sorbent material is introduced into the chamber at one or more positions at the top end of the chamber in such a way that it enters the ascending gas stream in a peripheral zone of the chamber.

摘要： A fluidized-bed process and apparatus involving a vertical column containing a plurality of perforated trays, each tray having a weir disposed on its upper surface to divide that surface into first and second sections, each of which has a plurality of apertures. One section of each tray constitutes 80 to 95% of the total tray surface area. Location of the weir on successive trays alternates from side to side of the column to provide for cross-flow of the fluidized material on the trays.
