    Abstract: A process for the conversion of oxides of nitrogen to nitrogen gas comprises the step of passing the oxide of nitrogen over a reactant carbon fiber material at a temperature of from 450°C to 750°C. The process may be carried out continuously, a carbon-containing gas such as carbon monoxide or methane being passed with the oxide of nitrogen over the reactant carbon fiber material optionally with the co-use of hydrogen. The reactant carbon fiber material may comprise carbon and a host material comprising reduced metal and a support material.

    Abstract: A nitrile barrier resin composition which comprises a blend of (1) a copolymer produced by the polymerization of a major proportion of a mono-unsaturated nitrile and a minor proportion of another monovinyl monomer component polymerizable therewith optionally in the presence of a preformed diene rubber; (2) a carboxylic acid; and (3) an alkaline filler containing a polyvalent cation.
    The physical properties of a nitrile barrier resin, particularly the tensile modulus, heat distortion temperature and processability, are improved by including therein the carboxylic acid processing aid and the alkaline filler material.
