Claim:
1. A system for preventing a catalyst from overheating, the system comprising: a first reactor filled with a catalyst at least in part and configured to receive reaction gas and produce product gas; and a second reactor at least partially filled with a catalyst discharged from the first reactor and configured to cool the catalyst discharged from the first reactor, wherein the catalyst is circulated between the first reactor and the second reactor by injecting the catalyst cooled in the second reactor into the first rector, wherein the second reactor comprises: a path of a cooling fluid passing through a catalyst bed in the second reactor; and a path to allow the reaction gas to pass through the catalyst bed in the second reactor, and wherein the reaction gas is pre-heated by heat exchange with the catalyst during passing through the path of the reaction gas and then supplied to the first reactor.
