The influence of the delignification modes of Miscanthus sinensis and cereal husks in ethylene glycol on the pulp quality has been investigated. It was found that the absence of a catalyst in the cooking liquor does not lead to delignification. The introduction of a catalyst - hydrogen chloride accelerates delignification while pentosan hydrolysis proceeds. Ethylene glycol regeneration is carried out by vacuum distillation of the cooking liquor.
