CATALYST AND METHOD FOR PRODUCTION OF CHLORINE BY GAS PHASE OXIDATION

Document Type and Number:

Japanese Patent JP2016175079

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a catalyst for preparation of chlorine by catalytic gas phase oxidation of hydrogen chloride with oxygen, the catalyst having enhanced stability.SOLUTION: A catalyst composition comprises at least tin dioxide as a support material and at least one ruthenium-containing compound as a catalytically active material. The support material comprises, as an additional secondary constituent, a compound of an element or an element selected from among Nb, V, Ta, Cr, Mo, Au, In, Sc, Y and lanthanoids, especially La and Ce, preferably niobium or a niobium compound.SELECTED DRAWING: None
