Abstract

Se proporciona un método de pretratamiento de material fibroso triturado con carbonato de sodio y luego coccion del material pretratado en presencia de antraquinona (AQ). La pulpa resultante producida tiene un rendimiento superior, resistencia mejorada y mejor blanqueabilidad en comparacion con la pulpa producida por métodos del arte previo. La AQ también se puede introducir a la etapa de pretratamiento con carbonato. El método además puede incluir un pretratamiento con ácido que proporciona propiedades mejoradas a la pulpa producida.
