NOVEL CATALYST CARRYING STRUCTURE AND DIESEL PARTICULATE MATTER REMOVING DEVICE USING THE SAME

摘要

A catalyst carrying structure, which comprises at least one sheet of metal net being wound into the form of a roll and having, carried thereon, a catalyst for removing a particulate matter in a diesel exhaust gas; a diesel particulate matter removing device having said catalyst carrying structure; and a method for treating a diesel exhaust gas, characterized by treating the gas with said diesel particulate matter removing device. The above catalyst carrying structure has a great surface area per unit volume and can decompose a particulate matter (PM) with good efficiency at a relatively low temperature, while removing nitrogen oxides (NO
