Abstract

original image

Deacon process revisited: A shaped RuO2/SnO2–Al2O3 catalyst was designed for highly active and stable performance in HCl oxidation to Cl2. In addition to its binding effect, alumina acts as a stabilizer to prevent sintering, endowing the catalyst with extraordinary longevity. Pilot tests give solid prospects for industrial implementation of this catalytic system.
