  • Patent number: 10378411
    Abstract: The present disclosure is directed at a dosing method and apparatus for treatment of reductant urea solutions with water soluble organometallic catalyst precursors which convert to active catalyst compounds in diesel exhaust gas systems. The active catalysts then promote hydrolysis of isocyanic acid into ammonia and/or decomposition of relatively high molecular weight deposits which deposits may otherwise reduce selective catalytic reduction efficiency.
    Type: Grant
    Filed: January 3, 2018
