Integral valorization of tagasaste (Chamaecytisus proliferus) under hydrothermal and pulp processing
چکیده انگلیسی

Tagasaste wood (Chamaecytisus proliferus L.F. ssp palmensis) was characterized, chemical and energy terms, and assessed its potential as a lignocellulosic raw material, and its integral fractionation by autohydrolysis and delignification with ethanol. The hydrothermal treatment of the raw material at 175–185 °C provided a liquor containing a substantially increased amount of oligomers (between 16.6% and 47.4% as percentages with respect to the content of the raw material in each polymer fraction). A cellulose pulp with autohydrolysis treatment increased yields (53–60%), reduced Kappa number (28.8–34.6) but also viscosity (755–857 mL/g), and decreased paper strength (2.97–5.22 kN m/kg). However, beating ethanol cellulose from tagasaste was found to improve its strength-related properties more markedly than in soda pulp from the same material (tensile index of 44 kN m/kg).
