Abstract

Métodos y sistemas para producir de manera continua pulpaje químico a partir de una suspension acuosa con material de madera de frondosas molido sometiendo dicha suspension a una primera etapa de coccion en condiciones suficientes para reducir el contenido de lignina tipo siringil (s-lignina) en el material de madera de frondosas en comparacion con contenido de lignina tipo guayacil (g-lignina) allí presente y luego sometiendo la suspension con material de madera de frondosas molido a una segunda etapa de coccion en condiciones suficientes para reducir el resto del contenido de g-lignina allí presente después de la primera etapa de coccion.Methods and systems for continuously producing chemical pulp from an aqueous suspension with ground wood material by subjecting said suspension to a first cooking stage in sufficient conditions to reduce the content of siringil-type lignin (s-lignin) in the hardwood material in comparison with lignin content type guayacil (g-lignin) present there and then subjecting the suspension with ground hardwood material to a second cooking stage in sufficient conditions to reduce the rest of the content of g- lignin present after the first stage of cooking.
