Title:
POROUS METAL HONEYCOMB SUPPORT OF AN AUTOMOBILE EXHAUST GAS CLEANING CATALYST
Document Type and Number:
WIPO Patent Application WO/2004/080594
Kind Code:
A1
Abstract:
This invention relates to a porous metal honeycomb support of an automobile exhaust gas cleaning catalyst. It is mainly a column support formed by calcining metal grains, with many fine pores between the metal grains that are linked to each other. And there are also many linked pores between the low and high bottora of the column support. Because the metal grains on the surface are rough, the catalyst coat is relatively finn and not easily to, be blown off by the vent gas after the said porous metal honeycomb support is coated with noble metal catalyst. In addition, because there are many fine i pores between the metal grains, the gas can contact with the catalyst effectively, and so the conversion efficiency can be improved greatly.
