Abstract: The invention relates to an extrusion die for the manufacture of monolithic adsorption tubes having a solid body portion with a multiplicity of tunnels for the passage of gas. The die comprises a multiplicity of rods positioned within an outer cylindrical housing and oriented parallel thereto. The rods are supported near the entrance end of the housing, by at least two sets of ribs, each set of ribs arranged in a geometric pattern and oriented perpendicular to the cylindrical housing. The rods provide the form for tunnels in the extruded monolithic adsorption tube.

Abstract: An adsorbent-based air conditioning system for conditioning an air supply to an enclosed space, such as a building, room, or the passenger compartment of a motor vehicle, aircraft, or the like, utilizes interchangeable adsorbent-containing vessels. Two of the vessels are employed to condition the air supply with respect to temperature and humidity while, at the same time a third and, optionally, a fourth vessel are regenerated by drying and cooling to provide replacements vessels as needed. In operation, ambient air is dehumidified by passing through vessel 1 and the moisture collected in the vessel by adsorption. The exiting air may be cooled by means of a heat exchanger, then directed through vessel 2, containing moist adsorbent, for further cooling and humidification. The air is then supplied to the room, or other space to be conditioned.

Abstract: A process to absorb more than one component from a gaseous stream comprising passing the gaseous stream sequentially in contact with separate and distinct adsorbent masses wherein not all of the more strongly sorbed component is removed in a single adsorbent mass. The process exhibits improved overall efficiency over conventional multicomponent adsorption processes.

Abstract: An apparatus and process for producing attrition-resistant moving bed particles with improved efficiency.

The process exhibits improved overall efficiency over conventional single component processes.

Abstract: A valve system for particulate solid flow control which is especially advantageous where combined particulate solid and fluid flow control through a pressure level change is desired, such as might be used in conjunction with a lockhopper.

Abstract: An attrition resistant molecular sieve composition comprising a generally spherical, high porosity molecular sieve particle having an exposed surface coated with a thin, generally uniform layer of solid lubricant which can be employed in fixed, moving or fluidized beds with low attrition and without significantly reduced activity.

Abstract: A process and apparatus which enables direct heat transfer temperature swing regeneration without unwanted mass transfer during heat exchange steps resulting in reduced energy and purge gas requirements.
