Abstract
La presente invención es un mejoramiento en el procedimiento químico convencional para realizar pulpa por medio del mejoramiento de la eficienciapor la que los componentes de licor de cocción de pulpa penetran en la madera y permiten que lali gnina y las resinas sean extraídas desde los materialescelulósicos. Se ha hecho un descubrimiento sorprendente respecto a que la adición de ciertos agentes tensioactivos o combinaciones de ciertos agentestensioactivos al licor blanco en unproc eso para realizar pulpa convencional mejora el régimen de penetración de licor blanco en la pulpa de celulosa yreduce los tiempos de ciclo para realizar pulpa. El proceso de acuerdo con la invención comprende poner en contacto lasastillas de madera y lo similarcon un auxiliar de digestor que es una mezcla líquida o composición, la cual también se reivindica comprendida por licor blanco que contiene por lo menosun agente tensioactivo como el descripto precedentemente en lapresente. L a concentración de agente tensioactivo en la mezcla líquida y el tiempo decontacto con las astillas de pulpa son cada uno ajustados para que los componentes resinosos se extraigan de la pulpa sin degradación considerabledela celulosa. D espués de poner en contacto por lo menos una porción de la mezcla líquida - pulpa resultante la combinación se calienta a una temperaturade digestión típicamente aproximadamente superior a 150°C. La calefacción se denominatambién como cocción . El proceso de acuerdo con la invención resultaen (1) aceleración de la penetración del licor de cocción por reducir su tensión de superficie, (2) la disolución y la emulsificación de los componentesresinosos que inhibenla penetración de lic or y la difusión, por lo cual mejora significativamente la penetración del licor en la astilla de madera, y(3)mejora
