Title: Diesel soot-particle filter and process for the production thereof
IPC: F01N3/035
Filed: 1987-09-01
Abstract: Diesel soot-particle filter of at least one filter element as support for a catalyst prepared with the use of a metal oxide, characterised in that the support comprises a foamed ceramic or metal body, preferably a ferro-chromium-aluminium alloy, having a pore index of at least 25 PPI, the pore surfaces of which are continuously coated with a metal oxide or a plurality of metal oxides of groups Ib, Vb, VIb, VIIb or of the Fe group of the periodic table of the elements, preferably vanadium pentoxide, as catalytically active material. The catalytically active material, to improve its adhesion to the support, contains aluminium oxide in an amount of up to 30 % by weight, preferably between 5 and 15 % by weight. For the catalytic oxidation of hydrocarbons, it further contains metal mixed oxides, in particular copper chromite, furthermore iron oxide and cobalt oxide and an alkali metal salt or alkaline earth metal salt and/or zirconium dioxide. The preparation is carried out by grinding the materials in the wet state to a maximum particle size of 10  mu m and suspending the product with water, establishing a pH between 5 and 8 until a viscosity of less than 5 cP is achieved, whereupon the foamed ceramic or metal body is impregnated with suspension by dipping and the coating in the pores is stabilised by drying at 110@C and 200@C and heating at up to 700@C.
