Abstract

Métodos y sistemas para preparar residuos agrícolas u otras materias primas agrícolas para su uso como pulpa. El método incluye proporcionar residuos agrícolas no madereros (e.g., forraje de maíz) u otra materia prima agrícola que incluya fibras agrícolas, pu1perizando químicamente las fibras agrícolas en un proceso preliminar de palpación química alcalina a una baja consistencia y a una baja temperatura para producir fibras agrícolas parcialmente pulperizadas, incluyendo dicha etapa separar la 1ignina y hemice1ulosa de las fibras agrícolas parcialmente pulperizadas, introduciendo las fibras agrícolas parcialmente pulperizadas en un primer reactor, en donde el primer reactor opera a una temperatura baja de menos de 100ºc (e.g., 65ºC), introduciendo las fibras agrícolas del primer reactor en un segundo reactor, en donde el segundo reactor opera a una temperatura baja, de menos de 100ºc (e.g., 94-96ºC), operando el segundo reactor a una temperatura más alta que el primer reactor, para producir fibras agrícolas pulperizadas.
