【 摘 要 】

The enhanced utilization of plant biomass for bioenergy is a key factor to contribute to a sustainable development. In this research work 3 Hungarian hardwood species Populus x euramericana. cv. 'I-214', Populus x euramericana. cv. 'Pannonia', Robinia pseudoacacia (2 Poplars and Black locust) were investigated on heating value and ash content. 3 age classes were defined (from 7 years up to 29 years) in order to analyse the effect of the tree's age on the investigated properties. Significant differences were found between the bark, the sapwood and the heartwood. Age influenced the heating value to, but differently for bark, heartwood and sapwood. The 10 years old Black locust's bark showed the highest heating value (21,53 MJ/kg), while the 19 years old Pannónia poplar heartwood gave the lowest value (17,68 MJ/kg). In terms of ash content dramatic differences have been proven between bark and xylem (sapwood and heartwood). The 26 years old Black locust heartwood had 0.2 % ash content only, while the 10 years old Pannonia bark 5.2%.
