Title: CATALYST FOR EFFICIENT CONVERSION OF HYDROGEN CHLORIDE TO PRODUCE CHLORINE GAS
Abstract:
A catalyst for efficient conversion of hydrogen chloride to produce chlorine gas, characterized in that based on mass percentage, a catalyst precursor consists of: 70% to 80% of component A, 5% to 10% of component B, 1% to 2% of component C, 0.1% to 0.3% of component D, and the balance of SiO2; the component A being Na--type mordenite; the component B being Cu2+; the component C being Fr+ or Cs+; and the component D being Re3+ or Ir3+. The catalyst is suitable for the high conversion of hydrogen chloride to produce chlorine gas.
