Abstract

"PROCESSO PARA A PRODUçãO DE POLPA". A presente invenção é um processo para a produção de polpa a partir de material de lignocelulose fibroso usando uma etapa de tratamento que expõe o material a ácido oxálico, ou ácido oxálico e bissulfito de sódio, antes da polpação. A polpação do produto resultante requer menos entrada de energia e fornece uma polpa com melhores propriedades fisicas em comparação com materiais não tratados.
