ABSTRACT:
A distillation-reactor for separating constituents of a feedstock having similar boiling points includes at least one stage with containing screens defining a series of containment volumes for a heterogeneous particulate catalyst. The catalyst is fluidized within the volumes defined by the containing screens by the action of vapor passing through the tray. Liquid flowing across the tray intimately contacts the fluidized catalyst and vapor without the occurrence of liquid back-up or high pressure drop.
