ディーゼル酸化触媒複合体
Document Type and Number:
Japanese Patent JP6411344
Kind Code:
B2
Abstract:
Oxidation catalyst composites for the treatment of exhaust gas emissions, such as the abatement of unburned hydrocarbons (HC), and carbon monoxide (CO) and the oxidation of NO to NO2 are disclosed The catalyst composites comprise two washcoat layers containing two different compositions of platinum group metals to optimize the NO2 exiting the catalyst composite. The key to improvement in NO oxidation is to have one catalyst layer that contains Pt while being substantially free of Pd. Methods and systems utilizing the catalyst composites are also disclosed.
