Abstract: A catalyst for the selective oxidation of alkanes and alkenes has been developed. The catalyst consists of a noble metal component such as platinum and a SbOx component. A unique feature of the catalyst is that the noble metal component is present as particles of which from about 1 to about 30 mole % of each particle is in the form of a noble metal/Sb alloy. Optionally a modifier and/or a refractory inorganic oxide may also be added to the catalyst. A process for preparing the catalyst is also presented.

Abstract: The present invention discloses a method of continuously processing a ribbonlike material. The method is characterized by comprising a preliminary polishing step in which surface defects of a material pulled out from an uncoiler are removed and the surface of the material is semi-finished by abrasion in combination with electrolytic polishing, a final polishing step in which the surface of the material is mirror-finished by abrasion in combination with electrolytic polishing, a washing and drying step in which the material is washed and dried with extraneous matter on the surface of the material washingly removed, a surface inspection step in which the thus finished surface of the material is inspected as to surface roughness and defects, a surface protection step in which a protective film is applied to the finished surface of the material, and a press step in which the material is cut into a predetermined size.

Abstract: The present application discloses an equipment for continuously processing a band-shape material comprising transverse sliding shafts disposed on a base table, a basal board which freely slides transversely along said transverse sliding shafts, transverse-feeding means by which said basal board is quickly and/or slowly moved transversely, vertical sliding shafts disposed on said basal board, a tool of abrasion in combination with elctrolytic polishing which freely slides vertically along said vertical sliding shafts, vertical-feeding means by which said tool is moved vertically against said basal board and a polishing head which is disposed on said tool and composed of electrodes for electrolysis and abrasive matters for abrasion and by which continuously sent band-shape material is polished.
