Resumo

In recent years, global environmental problems, particularly, global warming due to CO2 emission, have become substantially evident. Research on the effective utilization of recyclable biomass-energy resources are required to reduce the accumulation of atmospheric CO2. Currently, gasification and combustion technologies have been actively developed. Some of these are the development of entrained flow gasifiers for woody biomass, studies on biomass-coal hybrid combustion, and biomass oil production technologies for establishing a technology that yields low environmental loading. Because the pyrolysis product differs according to the type of biomass material in the gasification and combustion, the types of biomass materials must be systematically examined. This paper reports on the pyrolysis product of various biomass materials. In particular, the primary yields of total volatiles, tar and non-condensable gases, together with the composition of non-condensable gases, are measured as a function of temperature. The use of a high-intensity infrared heating source, in conjunction with a nonabsorbing carrier (viz. argon), is reported to reduce the significance of secondary gas-phase pyrolysis reactions. When the temperature of the Pt cell reached 800????, radiative heating was stopped (applied voltage to the apparatus was cut off), and the sample was rapidly cooled. The evolved tar and gases were quenched by the ambient outside the biomass sample. Then the first volatile yields of various biomass materials were systematically investigated in the experiments.
