Biorrefinería AB It was proposed that pre-hydrolysing tule (Typha domingensis Pers) wouldmake it possible to produce handsheets with strength-related propertiessimilar to those of conventional commercial paper, in addition tovalorizable hemicelluloses. The hypothesis was tested with a biorefiningscheme involving autohydrolysis. Conditions were optimized to maximizethe extraction of hemicelluloses while preserving glucan integrity. Theautohydrolysis at a liquid to solid ratio of 13 at 141 °C for 45 min (optimizedconditions) provided a commercially useful liquor containing primarily tulehemicelluloses. The autohydrolysis of tule before alkaline extraction madeit possible to obtain a valuable liquid phase comprising between 23.3%and 71.6% of all hemicelluloses in the raw material. The gross heatingvalue for the hydrolyzed tule was increased (1.6% to 7.9 %) with respectthe raw material. The solid phase was subjected to soda–anthraquinonepulping. The yield, ethanol extractives, kappa number, viscosity, glucan,xylan, Klason lignin, soluble lignins, as well as the tensile index wereevaluated. Tule was found to be amenable to industrial processing for theproduction of quality cellulose derivatives. Autohydrolysis providedvalorizable liquor in addition to solid that yielded soda–anthraquinone pulphaving properties similar to those obtained in its absence, but using milderoperating conditions.
