摘要: The invention relates to a process for the production of hemicellulose hydrolysate and special pulp through two steps, first step comprising prehydrolysis material second dissolving lignin contained in prehydrolyzed material. According is carried out by means neutral sulphite cooking with anthraquinone or derivative thereof as catalyst, pH liquor being initially at least 10.
