Abstract

PROCESSO PARA DESIDRATAÇÃO DE CELULOSE MICROFIBRILADA. A presente invenção refere-se a um processo para desidratação de uma suspensão compreendendo celulose microfibrilada, em que o processo compreende as etapas de prover uma suspensão compreendendo uma celulose microfibrilada e um líquido, submeter a dita suspensão a uma primeira pressão mecânica, a fim de desidratar a referida suspensão, e submeter a suspensão a uma segunda pressão mecânica, cuja segunda pressão mecânica é maior que a primeira pressão mecânica.
