Aluminium phosphate supported copper phosphate catalytic converter to reduce nitrous oxides and particulate matter from engine emission

Abstract

To meet the strict emissions regulations, it is required to test and identify highly active and durable catalysts. This paper analyzes the potential of catalytic system in a diesel engine using aluminium-phosphate supported copper phosphate catalytic converter to control nitrous oxide and particulate matter. The particulate matter is reduced by Catalyzed Diesel Particulate Filter (CDPF) and Diesel Oxidation Catalysts (DOC) systems. The soluble organic fractions of diesel particulate are oxidized by DOC system of the newly developed catalyst coated wire meshes, and the un-soluble fractions of particulate matter are filtered by the same wire mesh filter materials. The experimental results from this investigation demonstrate that 40.58% of NOx reduction is achievable, which clearly shows the possibilities of replacing the noble metal catalysts
