Selective oxidation catalyst process for preparing the catalyst and process using the catalyst

摘要

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.
