  • PROCESS AND APPARATUS FOR REMOVING SOLID CATALYST
    Publication number: 20230117401
    Abstract: Spent catalyst (500) is removed from process microchannels (310) of a Fischer-Tropsch reactor by directing a jet of air (4) from an air knife (1) through slots of a protecting member (2). The air knife is traversed across successive rows of process microchannels (310) in direction A. The spacer member (2) protects an internal microchannel architecture (315) of the process microchannels against damage by the air jet (4) which may approach or exceed sonic velocity as it is directed into the process microchannels.
