Abstract

a presente invenção se refere a um método para a precipitação de lignina a partir de licores de polpa de organossolve. o licor de polpa de organossolve é introduzido aqui para uma dispersão aquosa já existente de partículas de lignina ou para um filtrado de uma dispersão aquosa de partículas de lignina como precipitante, em que uma fase que compreende lignina separada no estado dispersado é produzida.
