Porosity and pore size distribution of black cherry carbonized in an inert atmosphere

Abstract

Changes in total porosity, pore size distribution, apparent density, and real density as a function of carbonization temperature (up to 900/sup 0/C) were investigated using a mercury porosimeter. Total measured intrusion, total porosity, pore size distribution, and apparent density change as a function of carbonization temperature. Total porosity (up to 600/sup 0/C), apparent density (up to 600/sup 0/C), and pore size distribution above 1.75 ..mu..m are linear functions of carbonization temperature. Total measured intrusion and total porosity increase with increasing carbonization temperatures up to 600/sup 0/C and then decrease with carbonization temperatures up to 900/sup 0/C. Apparent density decreases with carbonization temperatures up to 600/sup 0/C and then increases with increasing carbonization temperatures.
