Outline of Final Research Achievements

In this research, microscopic visualization of the pyrolysis in wooden biomass was conducted by using the BL20B2 beamline at “Spring-8”, a large synchrotron radiation facility. Two kinds of measurements, that is, the X-ray computed tomography (CT) and the X-ray transmission imaging, were applied to observe difference internal structure of wood caused by thermal pyrolysis. 　There is a possibility that the state from which a density distribution internal specimen changes can be measured from the X-ray transmission intensity.
