Abstract

Carbon dioxide concentration of railroad passenger cabin is obliged to be kept lower than guideline values of 'Indoor air quality guideline for public transportations', but actual carbon dioxide concentration frequently exceeds this guideline value. Ventilation is most desirable to lower carbon dioxide concentration but there are some cases when the ventilation is not applicable. In this study, carbon dioxide concentration control method using adsorbents was presented. The cation of zeolites were exchanged with various kinds of cations, and the carbon dioxide adsorption performance of the zeolites were studied. The various kinds of cations, solvents, and zeolites were introduced, and it was found that some cation-exchanged zeolites showed good carbon dioxide adsorption performances. It is expected that the obtained results will be used to lower carbon dioxide concentration of railroad passenger cabin.
