Abstract: A process for the destruction of organic contaminants from wastewater streams and solid surfaces, including soil. The process comprises removing volatile organic compounds from the wastewater stream or surface by steam stripping and then contacting a stream comprising steam and the stripped organic compounds with a catalyst at an elevated temperature so as to convert the hydrocarbon portion of the organic compounds to a mixture of hydrogen and carbon dioxide.

Abstract: Vanadium phosphorus mixed oxide containing catalysts are prepared by sequentially forming an alpha-VOPO.sub.4 catalyst precursor in aqueous media, and thereafter partially reducing a portion of the vanadium to a valence state of +4 in an organic liquid reducing media, in the absence of corrosive reducing agents. The catalysts exhibit excellent activity for the production of maleic anhydride from 4 carbon atom hydrocarbons such as n-butane.
