Abstract
Viene descritto un procedimento per la eliminazione di Sox (SO2+SO3) (desolforazione) e di Nox (denitrazione) dai gas di combustione (fumi), senza formazione apprezzabile di ossido nitroso (N2O), in cui i gas della combustione vengono dapprima sottoposti a desolforazione per contatto con un catalizzatore solido in particelle di ossido di rame supportato su allumina. Operando ad una temperatura nell'intervallo da 350 a 450°C; ed i gas di combustione così desolforati, previa aggiunta di ammoniaca, vengono successivamente sottoposti a denitrazione per contatto con un catalizzatore solido in particelle di ossido e/o solfato di rame supportati su allumina, operando ad una temperatura da 100A 300°C.Il procedimento viene preferibilmente condotto con il catalizzatore in forma di detto mobile discendente in un reattore a flusso radiale, dotato di mezzi di raffreddamento dei gas, posti esternamente o internamente al reattore, tra lo stadio di desolforazione e quello di denitrazione.
