Latest Patents

Liederman holds a patent for the "Reactivation of automobile exhaust oxidation catalyst." This invention addresses the challenge of thermal deactivation in oxidation catalysts that contain platinum or other noble metal components. The patent describes a method where the catalyst is reactivated by exposing it to a halogen-containing gas at temperatures ranging from 500°F to about 1000°F. The process involves passing carbonyl halide or a mixture of carbon monoxide and halogen over the catalyst, which effectively reduces the CO-oxidation and hydrocarbon-oxidation temperatures to levels comparable to that of a fresh catalyst. The preferred treatment involves carbonyl chloride or a carbon monoxide-chlorine mixture, and this method can also be applied to noble metal-containing reforming catalysts.
