Multi-stage ammonia production for sorption selective catalytic reduction of NOx
文献摘要：
Sorption selective catalytic reduction of nitro-gen oxides(NOx)(sorption-SCR)has ever been proposed for replacing commercial urea selective catalytic reduction of NOx(urea-SCR),while only the single-stage sorption cycle is hitherto adopted for sorption-SCR.Herein,various multi-stage ammonia production cycles is built to solve the problem of relative high starting temperature with ammonia transfer(AT)unit and help detect the remaining ammonia in ammonia storage and delivery system(ASDS)with ammonia warning(AW)unit.Except for the single-stage ammonia production cycle with MnCl2,other sorption-SCR strategies all present overwhelming advan-tages over urea-SCR considering the much higher NOx conversion driven by the heat source lower than 100℃and better matching characteristics with low-temperature catalysts.Furthermore,the required mass of sorbent for each type of sorption-SCR is less than half of the mass of AdBlue for urea-SCR.Therefore,the multifunctional multi-stage sorption-SCR can realize compact and renew-able ammonia storage and delivery with low thermal energy consumption and high NOx conversion,which brings a bright potential for efficient commercial de-NOx technology.
