摘要:
A honeycomb catalyst includes a honeycomb unit. The honeycomb unit has a plurality of through holes that are arranged in parallel in a longitudinal direction and partitions that are provided between the plurality of through holes. The honeycomb unit includes a first zeolite, a second zeolite, and an inorganic binder. The first zeolite includes a CHA-structured aluminosilicate having a Si/Al ratio of about 15 to about 50. The second zeolite includes a silicoaluminophosphate having a Si/(Si+Al+P) ratio of about 0.1 to about 0.25. A volume ratio of the first zeolite to the second zeolite is about 75:about 25 to about 90:about 10.
