Abstract:
Recent studies focused on the research for thermochemicalpretreated lignocellulosic biomass to replace fossil fuels. The improvementof the knowledge about pretreated lignocellulosics contributes to achieve the goal of renewable energy sources use, reducing greenhouse gas emissions and limiting climate change. Biomass participates in renewable energy production so that sustainable consumption and production patterns can by ensured by meeting Goals 7 and 12 of the 2030 Agenda for Sustainable Development. The subject of the present work relates to the enhancement of the thermal energy content of spruce sawdust through organosolv pretreatment. At the same time, the impact of the organosolv process parameters, i.e., time,temperature, and pH, was investigated and kinetic models were applied to fit the experimental data using the severity factor, R0*, which combines the effect of the temperature time and pH of the organosolv process into a single reaction ordinate. According to the results presented herein, the maximum heating value 24.4 MJ/kg was achieved at 180 oC for 50 min without sulfuric acid as catalyst. Consequently, organosolv pretreatedspruce sawdust could be an alternative renewable energy source as a coal substitute within the biorefinery and the zero-wastecircular economy concept.
