SELECTIVE CATALYTIC REDUCTION CATALYST USING LPG AS A REDUCTANT FOR REMOVING NOX

摘要

PURPOSE: A selective catalytic reduction catalyst for eliminating nitrogen oxide using liquefied petroleum gas as a reducing agent is provided to improve the eliminating performance of nitrogen oxide by being composed of noble metal and transition metals. CONSTITUTION: A selective catalytic reduction catalyst for eliminating nitrogen oxide using liquefied petroleum gas as a reducing agent carries Pd, Fe, Cu, Ce in a zeolite carrier. The content of the Pd is between 0.10 and 0.1 weight%, the content of the Cu is between 2 and 8 weight%, the content of the Fe is between 1 and 3 weight%, and the content of the Ce is between 0.5 and 2 weight% based on the total weight of the catalyst. The zeolite carrier is ZSM5.
