SILICOALUMINOPHOSPHATE PARTICLES, HONEYCOMB STRUCTURE, METHOD FOR MANUFACTURING THE SAME AND EXHAUST GAS PURIFYING APPARATUS |
摘要 |
Objects of the invention are to provide silicoaluminophosphate particles that have excellent NOx purification performance and can suppress water adsorption-caused contraction and water desorption-caused expansion and to provide a honeycomb structure that has excellent NOx purification performance and can suppress the breakage of the honeycomb unit due to the adsorption or desorption of water, a method for manufacturing the honeycomb structure, and an exhaust gas purifying apparatus including the honeycomb structure. The silicoaluminophosphate particles of the invention have a metallic oxide attached to silicoaluminophosphate particles with a ratio of an amount of Si to a sum of amounts of Al and P in a range of 0.16 to 0.33, in which a specific surface area is in a range of 250 m2/g to 450 m2/g, and an external surface area is in a range of 10 m2/g to 35 m2/g. |
