ABSTRACT:
Composition, method and apparatus for providing a surface stabilized source of HNCO by adsorbing gaseous or liquid HNCO on the surface of a substrate. HNCO stabilized in this manner is not reactive and is stable at or above ambient temperature. The HNCO can be provided by heating a reactant source material, such as urea. The substrate can be heated to release HNCO. The present invention is especially useful as a source of HNCO for reducing NO.sub.x in gas streams.
