RT Journal Article T1 Chemical and energetic characterization of species with a high‐biomass production : fractionation of their components A1 López Baldovín, Francisco A1 García Domínguez, Juan Carlos A1 Pérez Muñoz, Antonio A1 Feria Infante, Manuel Javier A1 Zamudio, Minerva A. M. A1 Garrote, Gil AB In this work, we determined the properties of cellulose pulp and paper from six different lignocellulosicmaterials [Eucalyptus globulus, Arundo donax, Leucaena diversifolia, Paulownia fortunei, sunflower stalksand Chamaecytisus proliferus (tagasaste)], as well as the calorific value and chemical composition of theirautohydrolysis liquor, with a view to assessing their potential for the obtainment of energy, sugars and otherchemical products. An integral fractionation method based on autohydrolysis and organosolv delignificationwas used for this purpose. Leucaena diversifolia; P. fortunei; a Paulownia “trihybrid” consisting of elongata,tormentosa and fortunei varieties; sunflower stalks; and C. proliferus exhibited holocellulose, glucan, xylanand acetyl group contents similar to, or higher than, those of E. globulus, A. donax and various otherlignocellulosic materials. The amounts of oligomers extracted from C. proliferus, P. fortunei, L. diversifoliaand sunflower stalks at the highest temperatures studied exceeded those provided by eucalyptus. Sequentialautohydroysis and organosolv delignification of L. diversifolia and C. proliferus provided cellulose pulp withan acceptable kappa number and paper sheets with good strength-related properties. Paulownia fortunei wasthe most interesting raw material among those tested; in fact, it provided ethanol pulp with a lignin content of3.7 –15.3% and a kappa number of 40.5–74.1 after autohydrolysis at 190 ºC, and paper with a tensile index of17.0–28.9 kN m/kg. These properties are similar to those of pulp and paper from eucalyptus wood. Inaddition, P. fortunei exhibited the highest calorific value among the studied materials (4683.8 cal/g).
