Fe(II)置换MEL型沸石及其制法、包含其的气体吸附剂、及一氧化氮及烃的除去法
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MEL型沸石及其制造方法、包含其的气体吸附剂、以及一氧化氮及烃的除去方法。本发明的Fe(II)置换MEL型沸石的SiO2/Al2O3比为10以上且30以下、并且是由Fe(II)离子进行离子交换而成。相对于Fe(II)置换MEL型沸石，Fe(II)的载有量较佳为0.001mmol/g～0.4mmol/g。该Fe(II)置换MEL型沸石可以通过以下方法而较佳地制造：将SiO2/Al2O3比为10以上且30以下的MEL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MEL型沸石载有Fe(II)离子。
摘要（英）：

The purpose of/problem addressed by the present invention is to provide: an Fe(II)-substituted MEL-type zeolite useful for the catalytic removal of a variety of gases; and a production method therefor. The SiO 2 /Al 2 O 3 ratio in this Fe(II)-substituted MEL-type zeolite is in the range of 10-30 inclusive. This Fe(II)-substituted MEL-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 MEL-type zeolite. It is preferable that the Fe(II)-substituted MEL-type zeolite be produced using a method in which an MEL-type zeolite having an SiO 2 /Al 2 O 3 ratio in the range of 10-30 inclusive is dispersed in an Fe(II) water-soluble-compound aqueous solution, and then mixed and agitated to cause the MEL-type zeolite to carry Fe(II) ions.
