Abstract:
Chemical characteristics of biomass affect efficiency of biomass conversion to energy and concurrently differences in plant composition should be established to determine the potential usefulness of the feedstock for conversion to biofuels in relation to the site of cultivation and to different management practices. This work will concentrate on the chemical characteristics relating to the quality of miscanthus (Miscanthus x giganteus) and poplar (Populus deltoides Bartr. cv. Lux) biomass cultivated with different level of nitrogen. Calorific value (LHV, low heating value), ultimate and proximate analysis, ash composition were determined on miscanthus and poplar short¬rotation coppice cultivated in Central Italy under different nitrogen fertilization (0 and 200 Kg ha-1) regimes. This experiment takes into consideration the 2-year old crop. The woody biomass of poplar showed a significant higher LHV than miscanthus one, coupled with a lower ash content. The nitrogen fertilisation did not affect the main biomass quality of the two perennial energy crops. Differences in biomass ash content and composition between the two species were observed. The woody biomass contains a lower level of silicon oxide (SiO2) than miscanthus ashes.
