摘要： PROBLEM TO BE SOLVED: To improve selectivity and separation performance and further, inhibit agglomeration of a catalyst metal. SOLUTION: Each of the titania-based porous bodies consists essentially of titania and has X-ray diffraction peaks assigned to lattice-planes having 0.290±0.002 nm interplanar spacing and contains also crystals other than anatase phase crystals. Accordingly, in each of the porous bodies, there are many crystal faces and the ratio of the amount of a catalyst metal deposited on one and the same crystal face to the total amount of the catalyst metal deposited on the porous body is low.

摘要： PROBLEM TO BE SOLVED: To make compatible for both of oxidation inhibition of SO2 and oxidation acceleration of HC in a catalyst contg. a transition metal phosphate compound as a carrier. SOLUTION: This catalyst is composed of a composite carrier consisting essentially of a zirconium phosphate, a titanium phosphate and a noble metal deposited on the composite carrier. As oxidation of SO2 is inhibited with the zirconium phosphate, while the oxidation of HC is accelerated with the titanium phosphate by using both of the phosphates it is possible to compatibly inhibit both of the oxidation of SO2 and acceleration of the oxidation of HC.

摘要： PROBLEM TO BE SOLVED: To improve the particulate removing activity of an oxidation catalyst in a low temp. region by producing the catalyst that burns and removes particulates from a carrier made of cerium oxide or zirconium oxide and a catalytic component made of oxide of Cu, Fe or Mn. SOLUTION: A catalytic component made of oxide of at least one kind of metal selected from among Cu, Fe and Mn is carried on a carrier made of at least one of cerium oxide and zirconium oxide to obtain the objective oxidation catalyst that oxidizes HC and SOF contained in exhaust gas from a diesel engine, etc., to purify the exhaust gas and reduces the amt. of particulates discharged. Since cerium oxide is liable to aggregate at >=500 deg.C, it is preferable that cerium oxide is previously stabilized, e.g. by adding 0.2-10mol% La, Y or Pr or 5-50mol% Zr and carrying out firing at >=600 deg.C.

摘要： PROBLEM TO BE SOLVED: To suppress the deterioration of a carrier and the grain growth of Pt at the time of high temperature endurance for a catalyst for cleaning an exhaust gas. SOLUTION: The catalyst for cleaning the exhaust gas is obtained by supporting Pt on a CeO 2 -ZrO 2 -Al 2 O 3 compound oxide in which Al/(Ce+Zr) is within a range of 1/20 to 50/20. The grain growth of CeO 2 -ZrO 2 particles is suppressed and the reduction of the specific surface area at a temperature close to 1,000°C is suppressed by allowing Al 2 O 3 to coexist. The low-temperature activity is enhanced by heat treatment at a high temperature, because Ce is made easily reducible and the oxygen release rate is enhanced. Further, the grain growth of Pt can be suppressed while maintaining heat resistance of the carrier by optimizing the ratio of Al 2 O 3 to CeO 2 -ZrO 2 . COPYRIGHT: (C)2005,JPO&NCIPI
