FE(II) SUBSTITUTED MEL TYPE ZEOLITE PRODUCTION METHOD THEREFOR AND GAS ADSORBENT INCLUDING SAME AND NITRIC OXIDE AND HYDROCARBON REMOVAL METHOD

摘要

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/AlO ratio in this Fe(II) substituted MEL t ype 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) substitute d 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 ha ving an SiO/AlO 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.
