Abstract
The oxidation of HBr to Br2 by a free-O2 containing gas is catalysed by copper or cerium oxides on an inert metal oxide support. The catalyst may be 2-50% of a copper or cerium oxide supported on zirconia, or alpha- or theta-alumina having a surface area of 5-100 m.2/g. The free-O2 containing gas may be air and may be in 20% stoichiometric excess. The gases may be passed over the catalyst, at 300-600 DEG C., atmospheric pressure, and at a combined velocity of 700-1500 volumes of gas per hour per volume of space occupied by catalyst.ALSO:A catalyst of cerium or copper oxide on an inert metal oxide support, for the oxidation of HBr to Br2 by a free O2-containing gas, is made by co-precipitating an aqueous solution of a copper or cerium compound e.g. copper or cerium nitrate, or cerium sulphate, with a salt of the inert support e.g. zirconyl chloride in the case of zirconia, by means of alkali e.g. NaOH, KOH, washing the precipitate, drying and calcining at 400 - 800 DEG C. The catalyst may be 2 - 50% CuO or CeO2 on zirconia, or a - or #qalumina having a surface area of 5-100 m2/g.
