Abstract

"MéTODO DE PRODUçãO DE UMA SOLUçãO OXIDANTE DE PERáCIDO MISTO E MéTODOS PARA TRATAMENTO DE SUBSTRATOS COM A MESMA". Um processo para tratamento de um substrato, por exemplo, polpa lignocelulósica ou polpas celulósicas com uma solução perácido mista compreendendo ácido percarboxílico e ácido de Caro que resulta em uma maior taxa de conversão do oxigênio ativo no peróxido de hidrogênio de modo a prover uma barata e eficaz deslignificação e/ou solução alvejante e o processo para fabricação de solução perácido mista.
