Disclosed is a process for producing chlorine, comprising feeding hydrogen chloride and oxygen into a catalyst layer that contains a hydrochloric acid oxidation catalyst and is formed in a reaction tube in a fixed bed multitubular reactor. The process is characterized in that the catalyst layer in one reaction zone in the fixed bed multitubular reactor is a catalyst layer formed by packing catalysts of a plurality of production lots, and the catalysts of the plurality of production lots satisfy requirement (I). Requirement (I): A/B = less than 1.20, provided that A = B and A and B are each a value of three significant figures. In the formula, A represents a pore volume of the catalyst of any one production lot in the catalysts of the plurality of production lots, ml/g; and B represents a pore volume of the catalyst of another one production lot, ml/g. |
