Abstract

ACTIVE SITES ARE CREATED ON THE SURFACE OF A LI/MGO CATALYST USED FOR THE SELECTIVE OXIDATION OF METHANE, BY THE GRADUAL LOSS OF CO(2) FROM SURFACE LITHIUM CARBONATE SPECIES IN THE PRESENCE OF OXYGEN. THE SITES CREATED ARE NOT STABLE BUT DISAPPEAR EITHER AS A RESULT OF REACTION WITH SO(2) TO FORM LI(2)SIO(3) OR BY THE FORMATION AND SUBSEQUENT LOSS OF THE VOLATILE COMPOUND LIOH. THE DEACTIVATION CAN BE REVERSED, AT LEAST PARTIALLY, BY TREATING THE CATALYST IN CO(2) UNDER REACTION CONDITIONS; IT CAN BE RETARDED IF LOW CONCENTRATIONS OF CO(2) ARE ADDED TO THE REACTION MIXTURE.
