Beschreibung
Zusammenfassung:	The purpose of the present invention is to provide a heterogeneous catalyst that exhibits high activity and high selectivity, specifically a catalyst suitable for oxychlorination for manufacturing 1,2-dichloroethane from ethylene, and a catalyst system. Provided are: a heterogeneous catalyst supported on a porous carrier, which is characterized by having the value of an integral of the hysteresis arising between an adsorption isotherm and a desorption isotherm for a gas adsorption method of 19% or less of the total value of the integral for the adsorption isotherm; and a catalyst system for manufacturing 1,2-dichloroethane that includes this catalyst and a diluent having a spherical shape, a circular cylindrical shape, or a hollow cylindrical shape.
