METHOD FOR REMOVING NITROGEN OXIDE OUT OF GAS

摘要

PURPOSE:To remove NOX by bringing gas containing NOX into contact with an adsorbent composed mainly of calcium phosphate. CONSTITUTION:Gas containing NOX is brought into contact with an adsorbent composed mainly of calcium phosphate such as artificial calcium phosphate, phosphate rock or the like. Said adsorbent adsorbs selectively NOX such as NO, NO2 or the like even when CO2 coexists in the gas, the removal efficiency of NOX is not affected by the coexistence of CO2 in the gas.
