Abstract

Método para recuperar lignina de bajo peso molecular a partir de un filtrado, donde la lignina de bajo peso molecular comprende moléculas de lignina que po-seen un peso molecular de 3000 g/mol o inferior, donde el filtrado se obtiene a partir de un proceso donde la lignina se precipita a partir del licor negro y el precipitado formado se separa del mismo mediante filtración dando lugar al fil-trado que comprende la lignina de bajo peso molecular formada.
