Abstract

В изобретении раскрывается усовершенствованный непрерывный способ производства целлюлозы из травянистого сырья, включающий этапы: (i) варка измельченного травянистого сырья в белом щелоке, содержащем 0,5-2,0 вес.% NaOH и 0,5-25,0 вес.% NaCl, при температуре 95-100°C; (ii) отбеливание коричневой целлюлозы в белом щелоке того же состава с кислородом (O2) и хлором (Cl2) при температуре 70-100°C с получением отбеленной целлюлозной массы; где (iii) лигнин и другие побочные продукты разделяются непрерывным электролизом, где белый щелок регенерируется вместе с O2 и Cl2 с целью отбеливания, завершая способ. Использование измельчения сваренной целлюлозной массы, а также отделение черного щелока на стадиях варки и отбеливания позволяет эффективно обрабатывать травянистое сырье и коричневую целлюлозу. Способ обеспечивает переработку различного травяного сырья, такого как стебли и листья сорго или кукурузы.
