Abstract: To provide a heterogeneous catalyst that exhibits high activity and high selectivity, specifically a catalyst suitable for oxychlorination to produce 1,2-dichloroethane from ethylene, and a catalyst system. Provided are: a heterogeneous catalyst supported on a porous carrier, characterized in that the integral value of the hysteresis occurring between an adsorption isotherm and a desorption isotherm by a gas adsorption method, is at most 19% to the total integral value of the adsorption isotherm; and a catalyst system for producing 1,2-dichloroethane, which comprises this catalyst and a diluent having a spherical shape, circular cylindrical shape or hollow cylindrical shape.

Abstract: The present disclosure relates to a partial oxidation catalyst that causes a light hydrocarbon partial oxidation reaction to proceed readily with high activity and high selectivity and a high-yield carbon monoxide production method using the same. The present disclosure further relates to a light hydrocarbon partial oxidation catalyst containing a zeolite supporting cobalt and rhodium.
