Abstract

"PROCESSO CATALìTICO SELETIVO REGENERATIVO". Sistemas e processo de redução catalitica seletiva regenerativa (RSCR) são providos por meio de que os níveis de NO~ x~ em gases são reduzidos misturando o gás com um reagente e então introduzindo o gás em um aparelho de RSCR para tratamento que requer aquecer o gás, fazer o gás sofrer uma ou mais reações catalíticas, e então dirigir o gás por uma área de transferência de calor, à qual o gás provê calor para uso com relação a ciclos sucessivos do processo de RSCR.
