  • Device for cooling and distributing mixed charges on fixed catalyst beds
    Patent number: 8568669
    Abstract: This invention relates to a device for cooling and distributing mixed charges on fixed catalyst beds for use in the cooling zone of descending flow reactors which comprises a flat tray fitted with collector and distributor tubes for liquid superimposed upon and connected to another flat tray of similar design to the upper tray. The device, which is of smaller size in comparison with other commercially available devices, is extremely simple to install industrially and compact, and has as its main characteristic the efficiency with which it promotes reduction of the temperature of the reaction medium when it receives the cooling fluid within the catalytic reactor.
