Removing Organic Impurities from Bayer Process Liquors

摘要

A process for treating a Bayer liquor by wet oxidation to oxidise organic contaminants in the Bayer liquor in which the wet oxidation process is conducted in the presence of a mixed Ce/Mn oxide. The catalyst may have nano-sized grains, and be supported on a mesoporous oxide support. The catalyst may also contain a platinum group metal.
