Abstract
"INTRODUçãO DE REFUGO DE CIANETO COMO UM REDUTOR DE NOX". A presente invenção é dirigida a sistemas e processos de redução de óxidos de nitrogênio de uma corrente de ar, por introdução de cianeto na corrente de ar e reação do cianeto com os óxidos de nitrogênio. Em algumas concretizações, a reação ocorre a uma temperatura entre 648,9 e 893,3<198>C (1.200 e 1640<198>F).
