  • REDUCTANT INJECTION SYSTEM AND METHOD FOR SELECTIVE CATALYTIC REDUCTION REACTION
    Publication number: 20230116996
    Abstract: The present disclosure relates to reductant injection system and method for a selective catalytic reduction reaction whereby urea is injected directly to an exhaust line where a denitrification reaction occurs without using an additional urea decomposition reactor and, thus, conversion from urea to ammonia can occur very fast.

  • Catalyst capable of directly decomposing urea and method for urea decomposition using the same
    Patent number: 11338272
    Abstract: The present disclosure relates to a catalyst for directly decomposing urea, a method for preparing the same and a system for decomposing urea including the same, whereby the efficiency of decomposing urea to ammonia may be improved while preventing the formation of a byproduct such as biuret at temperatures of 200° C. or below by controlling the oxygen composition of the catalyst including titania and ceria.
    Type: Grant
