Abstract

PROCESSO DE PRODUçãO DE DIóXIDO DE CLORO. A invenção refere-se a um processo de produção de dióxido de cloro através da redução de ions de clorato com peróxido de hidrogênio como um agente redutor em um reator tubular, preferencialmente na presença de um ácido mineral, em que o grau preferencial de conversão de clorato a dióxido de cloro no reator apresentar-se acima de em torno de 75 porcento, preferencialmente de em torno de 80 a 100 porcento.
