Fe(II)置换β型沸石、包含其的气体吸附剂及其制造方法、以及一氧化氮及烃的除去方法
摘要：
本发明的目的、课题在于提供一种在各种气体的催化除去时有用的Fe(II)置换β型沸石及其制造方法。本发明的Fe(II)置换β型沸石是SiO2/Al2O3比为7以上且小于10、并且由Fe(II)离子进行离子交换而成的Fe(II)置换β型沸石。相对于Fe(II)置换β型沸石，Fe(II)的载有量较佳为0.001mmol/g～0.4mmol/g。该Fe(II)置换β型沸石是通过以下方法而较佳地制造：将SiO2/Al2O3比为7以上且小于10的β型沸石分散在二价铁的水溶性化合物水溶液中，并进行混合搅拌，由此使该β型沸石载有Fe(II)离子。
摘要（英）：

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 0.001-0.4mmol/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.
