22 ABSTRACT OF THE DISCLOSURE An apparatus for testing performance of a catalyst in a gaseous phase catalytic reaction for a given reactant comprises a reactor, means for introducing a predetermined quantity of fluid reactant into the reactor and means for withdrawing the reaction mixture, including reaction products, from the reactor after a predetermined residence time. The reactor comprises a confined reactor volume with an upflow zone and a downflow zone. A device circulates fluids upwardly through the upflow zone and downwardly through the downflow zone where particulate catalysts in the upflow zone as fluidized by the upward flow of the fluid. The circulating device is adapted to circulate the fluid about the reactor volume at a rate which provides at any moment during the residence time for the reactants an essentially uniform concentration of reactants throughout the reactor volume to simulate conditions in a catalytic riser reactor.
