A PROCESS FOR THE PREPARATION OF A NOVEL HYDROPHOBIC COMPOSITE PD-MEMBRANE CATALYST USEFUL FOR NON-HAZARDOUS DIRECT OXIDATION OF HYDROGEN BY OXYGEN TO HYDROGEN PEROXIDE

摘要

A novel hydrophobic composite Pd-membrane catalyst useful for non-hazardous direct oxidation of hydrogen by oxygen to hydrogen peroxide A novel hydrophobic composite Pd-membrane catalyst useful for non-hazardous direct oxidation of hydrogen by oxygen to hydrogen peroxide. This invention particularly relates to a novel tubular hydrophobic composite Pd-membrane catalyst comprising Pd-metallic membrane and inorganic porous membrane, useful for non-hazardous direct oxidation of hydrogen by oxygen to hydrogen peroxide while avoiding premixing of feed hydrogen and oxygen gases and its method of preparation. The present invention also relates to a process for the preparation of the hydrophobic composite Pd-membrane catalyst.
