SMALL-ANGLE X-RAY SCATTERING INVESTIGATION OF THE EFFECT OF HEATING TEMPERATURE ON THE SUBMICROSCOPIC PORE STRUCTURE OF WOOD CHARCOAL*

Small-angle x-ray scattering investigations are performed on charcoal samples from black cherry wood which were heated to temperatures ranging from 600/sup 0/ to 2000/sup 0/C during pyrolysis. This report summarizes the results of these investigations which give information about the pore structure of black cherry wood. The authors also develop a general picture of the dependence of charcoal porosity on the temperature to which the wood was heated during pyrolysis.
