Abstract: HOMOGENEOUS AND HETEROGENEOUS CATALYSTS SYSTEMS CONTAINING CERTAIN PALLADIUM (II) SALTS AND COPPER (II) SALTS HAVE BEEN DEVELOPED. A SPECIFIED BALANCE OF A COPPER (II) HALIDE AND OF A NON-HALIDE COPPER (II) SALT IS MAINTAINED.

THE CATALYSTS ARE EFFECTIVE FOR OXIDIZING CO TO CO2 AND SO2 AND SO3.
