Tagasaste, leucaena and paulownia: three industrial crops for energy and hemicelluloses production

Abstract Background Burning fast-growing trees for energy production can be an effective alternative to coal combustion. Thus, lignocellulosic material, which used obtain chemicals with a high added value, is highly abundant, easily renewed and usually inexpensive. In this work, hemicellulose extraction by acid hydrolysis of plant biomass from three different crops ( Chamaecytisus proliferus, Leucaena diversifolia Paulownia trihybrid) was modelled the resulting solid residues were production. Results The influence nature raw material operating conditions extract fraction on heat capacity activation subsequent combustion process examined. power found depend markedly content material. low in hemicelluloses resulted lower increased yield after stage. also influenced treatment, gross calorific value (GCV) residue 0.6–9.7% relative starting addition, proliferus (Tagasaste) trihybrid (Paulownia) considerably than that materials, difference increasing degree conversion as well temperature concentration hydrolysis. tagasaste paulownia decreased conversion, treatment. No similar trend observed (Leucaena) owing its hemicelluloses. Conclusions Acid tagasaste, leucaena provided valorizable liquor containing large amount amenable efficient valorization There are many potential applications hemicelluloses-rich lignin-rich fraction, example multi-components bio-based feedstocks 3D printing, other value-added chemicals.
