ABSTRACT:
Disclosed are an apparatus adapted for use in a temporal analysis of products (TAP) system for studying catalytic reactions, a catalytic reactor provided with heat exchange capability and useful in the TAP system, and an apparatus for use in gas processing which can also be used in a TAP system. The gas processing apparatus includes a manifold for introduction of a plurality of gases into a gas processing system. The manifold comprises a plurality of channels through which gas may flow toward the gas processing system, and a mixing chamber having an inlet in communication with the plurality of channels and an outlet in communication with the gas processing system. At least one of the channels has a rapidly operable feed valve at the terminus of the channel at which it communicates with the chamber inlet. The mixing chamber has a void volume that is small relative to the working volume of the gas processing system. The catalytic reactor comprises any of several novel combinations of catalytic reaction chamber and constructions providing for transfer of heat to the chamber. The novel TAP system apparatus includes a housing and, within the housing, a catalytic reactor, a collimating slit or the like for providing a resolved pulse of product gas, an analytical device for real time analysis of the product pulse, and circuitry for coordinating the product pulse with scanning of the analytical device. The TAP apparatus may also include a cryogenic surface surrounding the product pulse path, a low residence time mixing zone ahead of the reactor, and/or a manifold of the type described above.
