Chemical Composition and Optimization of Liquefaction Parameters of Cytisus scoparius (Broom)

Invasive plants spread in such a way that they are threats to native species and biodiversity. In this context, work aims determine possible valorizations of Scotch Broom Cytisus scoparius (L.) Link. This harvested the Viseu region was used present study. The eco-valorization these renewable resources made by conversion into liquid mixtures can later be manufacture valuable products. For better understanding results obtained, chemical characterization branches (CsB) made. ash content, extractives dichloromethane, ethanol water, lignin, cellulose hemicellulose initial material were determined. Liquefaction reactor with different granulometry, temperatures time. Results show is mainly composed (36.1%), hemicelluloses (18.6%) lignin (14.6%) soluble ethanol, followed water small amount dichloromethane. Ashes around 0.69%, potassium calcium. Generally, smaller size, higher solvent ratio, temperature time liquefaction lead liquefaction. highest percentage 95% which than most lignocellulosic materials tested before.
