Title: Carrier for catalyst, no oxidation catalyst, and no oxidation method
Inventor: TAKAHASHI NAOKI
IPC: B01J27/16
Filed: 2002-11-19
Abstract: <P>PROBLEM TO BE SOLVED: To make high NO oxidation activity appear from a low temperature region even after a high temperature endurance test.  <P>SOLUTION: In a carrier for a catalyst, phosphorus (P) is added to a complex oxide in which an acidic oxide comprising at least one of ZrO<SB>2</SB>and TiO<SB>2</SB>and Al<SB>2</SB>O<SB>3</SB>are mixed on a primary particle level. Since NO adsorbency is improved and O<SB>2</SB>adsorbency is lowered by the change of the acid property of the multiple oxide by the addition of P, the adsorption of NO in an oxygen-redundant atmosphere is promoted so that the oxidation of NO in a low-temperature region is facilitated, and a specific surface area is also improved.  <P>COPYRIGHT: (C)2004,JPO
