Material Development of High Porous SiC for Catalyzed Diesel Particulate Filters

Low pressure-loss, especially for a catalyzed DPF(Diesel Particulate Filter), is a very significant performance. Higher-porosity DPF materials provide this lower pressure-loss parameter. This paper describes the successful material development of highly porous (up to 65% porosity) SiC materials. In addition, the influence of porosity and pore size distribution on pressure-loss and filtration efficiency with and without various catalyst loadings is presented.
