Abstract

processo de reciclagem. a presente invenção fornece um processo para separar celulose de uma carga de alimentação, compreendendo as etapas de: a) umectar a celulose com um primeiro sistema de solventes para formar celulose úmida; b) contactar a celulose úmida com um segundo sistema de solventes para formar uma mistura; c) manter a mistura a uma primeira temperatura por um primeiro período de tempo; d) manter a mistura a uma segunda temperatura por um segundo período de tempo para dissolver a celulose; e e) remover o primeiro e o segundo sistemas de solventes contendo a celulose dissolvida.
