PROCESS FOR REMOVING A NITROGEN GAS FROM MIXTURE COMPRISING N2 AND CO

摘要

N2 was sepd. from gas mixts. contg. CO and N2 by pressureswing adsorption by using >=2 adsorption columns contg. an adsorbent having selective adsorptivity for CO. Thus, 11.07 l converter gas contg. CO 88, CO2 2, N2 6.5, H2 3, and O2 0.5% was passed through the adsorption column contg. a modified mordenite-type zeolite. The recovered 5.15 l contd. CO 95, CO2 4.7, and N2 0.3%. Process partic. relates to the removal of N2 from blast furnaces or converter gas and there by seperates an easily adsorbable component from a poorly adsorbable component.
