  • Catalyst composition for inhibiting diesel engine white smoke emission
    Patent number: 10434499
    Abstract: The present invention relates to diesel oxidation catalyst (DOC) and diesel particulate filter (DPF) catalyst compositions, used for a smoke reduction apparatus, for inhibiting white smoke generated from a diesel engine and, more specifically, to a DOC, enabling minimization of sulphate adsorption, a DPF catalyst, enabling a sulphate desorption delay, and a smoke reduction apparatus having the DOC and DPF catalyst assembled therein. The diesel particulate filter catalyst composition, which is applied to the DPF, comprises oxide components selected from oxide components comprising manganese oxide and silver oxide.
