Abstract: A layered composition which can be used in various processes has been developed. The composition comprises an inner core such as a cordierite core and an outer layer comprising a refractory inorganic oxide, a fibrous component and an inorganic binder. The refractory inorganic oxide layer can be alumina, zirconia, titania, etc. while the fibrous component can be titania fibers, silica fibers, carbon fibers, etc. The inorganic oxide binder can be alumina, silica, zirconia, etc. The layer can also contain catalytic metals such as gold and platinum plus other modifiers. The layered composition is prepared by coating the inner core with a slurry comprising the refractory inorganic oxide, fibrous component, an inorganic binder precursor and an organic binding agent such as polyvinyl alcohol. The composition can be used in various hydrocarbon conversion processes including production of vinyl acetate.

Abstract: A device is disclosed for the generation of hydrogen peroxide. The device produces hydrogen peroxide on an as-needed basis through the use of electrolysis of water, remixing hydrogen and oxygen in an appropriate ratio, and reacting the hydrogen and oxygen in water in a reactor.

Abstract: A fluid and/or gas treatment unit containing a dynamic rotating assembly for passage of a fluid and/or gas therethrough comprises a housing having a generally cylindrical body and end walls, and a generally cylindrical member rotatable in the chamber and having a peripheral wall and end surfaces. A shaft extends coaxially through coaxial apertures in the housing end walls, and through a coaxial passage in the rotatable member with which it is engaged to rotate as a unitary assembly. Adjacent the inner surface of each end wall of the housing are, seriatim, a resiliently deflectable biasing element, a generally circular wear plate and a resiliently compressible, generally circular sealing member between the wear plate and the cylindrical member and rotatable therewith. A generally circular bearing member extends about the generally circular sealing member and the cylindrical member and is rotatable therewith.
