Title:
ZEOLITE FOR ABSORPTION AND DEVICE FOR REMOVING GAS USING THE SAME
Document Type and Number:
Japanese Patent JP2002321912
Kind Code:
A
Abstract:
To provide a zeolite for absorption capable of efficiently absorbing NOx gas.
The zeolite for absorption consists of a zeolite whose composition ratio of SiO2 to Al2O3 is expressed by formula (1): 2≤SiO2/Al2O3≤20. The zeolite is treated by ion exchange with one or more cations among copper ion, hydrogen ion, iron ion, cobalt ion, iridium ion, chromium ion and thallium ion.
