Abstract:
1. A chlorine production process comprising oxidizing hydrogen chloride with oxygen in a fluidized-bed reactor in the presence of a chlorine production catalyst, wherein the chlorine production catalyst comprises spherical particles containing copper element (A), an alkali metal element (B) and a lanthanoid element (C) and has an average sphericity of 0.90 or more, wherein the lanthanoid element (C) has a bond dissociation energy with oxygen at 298 K of 100 to 185 kcal/mol, wherein the content of the copper element (A) in the catalyst is 0.3 wt % to 4.5 wt %, wherein a terminal velocity of the catalyst in air calculated by the Stoke's law below is 0.10 m/sec to 1.0 m/sec and a particle density is 0.4 g/ml to 1.2 g/ml: wherein g: gravity acceleration ρ wherein a gas space velocity in the fluidized-bed reactor is 0.01 m/sec to 1.0 m/sec and the gas space velocity is not more than the terminal velocity of the catalyst.
