Abstract
"PROCESSO PARA O BRANQUEAMENTO DE POLPA DE MADEIRA E DE NãO MADEIRA, GRâNULO ATIVADOR DE BRANQUEAMENTO AGLOMERADO DE ESCOAMENTO LIVRE, E, SOLUçãO PARA O BRANQUEAMENTO DE POLPA DE MADEIRA E DE NãO MADEIRA". Polpa de madeira e de não madeira é branqueada por: a) adição de uma alíquota de aglomerado proveniente de um meio de distribuição de um sólido a granel, vantajosamente um silo, a uma solução diluída de peróxido de hidrogênio que é desejavelmente agitada para manter o aglomerado em suspensão, o aglomerado compreendendo: um ativador de branqueamento, vantajosamente tetracetil etileno diamina, (TAED); um aglutinante solúvel em peróxido, de preferência álcool polivinílico (PVOH); um sistema dispersante que compreende um agente de umidificação que é uma substância com baixa produção de espuma e que não se descolora em exposição a temperaturas de até 120<198>C e opcionalmente um sal, de preferência acetato de sódio, que é altamente solúvel em peróxido de hidrogênio; b) permitir que a TAED reaja substancialmente completamente com o peróxido de hidrogênio; c) ajustar o pH da solução de branqueamento por adição de álcali, de preferência de soda cáustíca e d) branqueamento da polpa por contato da mesma com a solução de branqueamento sob condições alcalinas.
