Title:
ガス混合物中のN2O含量を減少させる方法
Document Type and Number:
Japanese Patent JP4391720
Kind Code:
B2
Abstract:
A binderless X-type zeolite is used in a process for the reduction of the level of carbon dioxide and/or N2O in a gaseous mixture, the zeolite being obtained by converting the binder in a bound zeolite to zeolite such that the ratio of the adsorption capacity for carbon dioxide of the binderless zeolite to the adsorption capacity of the bound zeolite is greater than the weight ratio of the level of zeolite in the binderless zeolite to the level of zeolite in the bound zeolite.
