Fe(II)-SUBSTITUTED BETA-TYPE ZEOLITE, PRODUCTION METHOD THEREFOR AND GAS ADSORBENT INCLUDING SAME, AND NITRIC OXIDE AND HYDROCARBON REMOVAL METHOD |
摘要 |
The purpose of/problem to be addressed by the present invention is to provide: an Fe(II)-substituted beta-type zeolite useful for the catalytic removal of a variety of gases; and a production method therefor. The SiO2/Al2O3 ratio in this Fe(II)-substituted beta-type zeolite is equal to or more than 7 but less than 10. This Fe(II)-substituted beta-type zeolite is obtained by being subjected to ionic exchange with Fe(II) ions. It is preferable that the Fe(II) loading amount be in the range of 0.001-0.4 mmol/g of the Fe(II)-substituted beta-type zeolite. It is preferable that the Fe(II)-substituted beta-type zeolite be produced using a method in which a beta-type zeolite having an SiO2/Al2O3 ratio of equal to or more than 7 but less than 10 is dispersed in an Fe(II) water-soluble-compound aqueous solution, and then mixed and agitated to cause the beta-type zeolite to carry Fe(II) ions. |
