✦ Synopsis
integrated gasification/gas turbine technology, which offers high-energy conversion efficiencies. The electricity is produced by direct combustion of biomass, advanced direct combustion, gasification, and pyrolysis technologies, which are almost ready for commercial scale use. The major research and developments of the biomass power industry are focusing on gasifier scale-up, system analysis, and site-specific commercial feasibility studies.

Thermal behavior of biomass plant materials
Meszaros, E. et 01. Chrmia I Itzrlwier-ia Ekologicznu, 2002, 9. (I), 33-41.
TG-mass spectrometry was applied to detect the characteristics of a special poplar wood that was improved for energetic purposes. The thermal decomposition of the sapwood and the heartwood as well as the bark and the whole sample were studied. The effect of inorganic materials in the wood has also been studied. All samples were milled to a particle size smaller than 120 llrn and heated at lo-40"/min in an inert Ar atmosphere and in an oxidative (Ar:O = 79:21) atmosphere. Some samples were pretreated by washing with 60" Hz0 for 2 h to remove inorganic substances from the wood.

Utilization of urban and pulping wastes to produce synthetic fuel via pyrolysis Demirbas, A. f%rrg13 Soz/~c~c., 2002. 24. (3), 205-213. Major byproducts of delignification processes of lignocellulosic biomass include lignin degradation products. Lignin and its degradation products have fuel values. The yields of liquid and gaseous products from the solid waste pyrolysis increased from 23.8 to 49.7% with increasing temperatures at 584-683 K. The yields of liquid and gaseous products from the black liquor pyrolysis increased from 7.3 to 55.0% with increasing temperatures at 500-800 K. The yields of liquid and gaseous products from pyrolysis of the solid waste and black liquor samples increased with increasing temperature.
This increase is very sharp for the yields of liquid products from the solid waste at the same temperature range.
