Abstract: A method and an apparatus for evaluating performance of heterogeneous catalysts are provided to evaluate the performance of a catalyst acting on the elementary reaction to be evaluated objectively, by separating the reaction product progressing the side reaction easily from its environment by inducing supercritical fluid to a heterogeneous catalytic reaction system. An apparatus for evaluating performance of heterogeneous catalysts comprises a supercritical fluid supply device(100), catalytic reactor(300) and recovery device(400). The supercritical fluid supply device supplies the supercritical fluid. The catalytic reactor causes the reaction by a catalyst in a state that reaction raw materials are injected, and discharges the reaction products through a fluid supply tube of the supercritical fluid supply device. The recovery device separates and recovers the liquefied reaction products from the supercritical fluid by being supplied with the supercritical fluid dissolved with the reaction products.
