Abstract:	摘要： ► Biomass with higher volatile matter content has a higher carbon conversion rate. ► Applying the suitable pretreatment techniques that will enhance the bioenergy yield. ► The ratio of H2O/fixed carbon is a critical factor for enhancing the energy conversion. This study investigated the characteristics of 26 varieties of biomass produced from forestry, agriculture, municipality, and industry in Taiwan to test their applicability in thermal conversion technologies and evaluation of enhanced energy efficiency. Understanding the reactivity of the tested biomass, the cluster analysis was also used in this research to classify into characteristics groups of biomass. This research also evaluated the feasibility of energy application of tested biomass by comparing it to the physicochemical properties of various coals used in Taiwan’s power plants. The experimental results indicated that the volatile matter content of the all tested biomass was 60% and above. It can be concluded that the higher carbon conversion rate will occur in the thermal conversion process of all tested biomass. Based on the results of lower heating value (LHV) of MSW and non-hazardous industrial sludge, the LHV was lower than other tested biomass that was between 1000 and 1800kcal/kg. This is due to the higher moisture content of MSW and sludge that resulted in the lower LHV. Besides, the LHV of other tested biomass and their derived fuels was similar to the tested coal. However, the energy densities of woody and agricultural waste were smaller than that of the coal because the bulky densities of woody and agricultural wastes were low. That is, the energy utilization efficiency of woody and agricultural waste was relatively low. To improve the energy density of tested biomass, appropriate pre-treatment technologies, such as shredding, pelletizing or torrefied technologies can be applied, that will enhance the energy utilization efficiency of all tested biomass. 出版者： Kidlington: Elsevier Ltd 出版日期： 2012-12-01 出處： Applied energy, 2012-12, Vol.100, p.164-171 版權： 2012 Elsevier Ltd 版權： 2014 INIST-CNRS 識別號： ISSN: 0306-2619 識別號： EISSN: 1872-9118 識別號： DOI: 10.1016/j.apenergy.2012.06.063 識別號： CODEN: APENDX
