Abstract

"PROCESSO PARA PREPARAR SAIS DE HIDROXILAMÈNIO" A invenção diz respeito a um processo para produzir sais de hidroxilamónio por meio de redução catalítica de monóxido de nitrogênio com hidrogênio na presença de um ácido e um catalisador hidrogenizante, por meio do qual o monóxido de nitrogênio é purificado antes da redução catalítica por pelo menos um tratamento com óxidos porosos com base em silício e/ou alumínio ou com carbono ativado."PROCESS FOR PREPARING HYDROXYLAMINUM SALTS" The invention relates to a process for producing hydroxylammonium salts by means of catalytic reduction of nitrogen monoxide with hydrogen in the presence of an acid and a hydrogenating catalyst, by means of which the nitrogen monoxide is purified before catalytic reduction by at least one treatment with porous oxides based on silicon and / or aluminum or with activated carbon.
