Abstract

a presente invenção fornece, entre outras coisas, métodos incluindo as etapas de fornecer uma biomassa celulósica, associar a biomassa celulósica a um líquido orgânico para formar uma mistura, tratar a mistura para reduzir o teor de umidade da mistura para 30% ou abaixo (se necessário) e processar a mistura para produzir nanofibrilas de celulose em uma pasta fluida. em algumas modalidades, os métodos fornecidos levam em conta a produção de pastas fluidas com alto teor de sólidos contendo 4% ou mais de nanofibrilas celulósicas.
