Hesperaloe funifera was studied as a new raw material for paper manufacturing and lignin recovery. An experimental design was carried out to improve the quality of the obtained pulp varying the process temperature (155, 170 and 185 ºC), time reaction (20, 40 and 60 minutes) and soda concentration (5, 10 and 15 %). All experiments were carried out with 1% anthraquinone. Lignin content, holocellulose content, α-cellulose, viscosity, Kappa number and drainability were determined in the d...
