In order to learn about the effects of higher preparation temperatures, we recently examined a series of charcoals from black cherry (Prunus serotina Ehrh.) wood heated to temperatures from 600/sup 0/ to 2000/sup 0/C. The results are summarized in this report. In addition to obtaining some information about the pore structure of black cherry charcoal, we have developed a general picture of how the charcoal porosity depends on the temperature to which the wood was heated during pyrolysis. These results have led us to propose that the macropores in charcoals are similar to those in wood and that the main effect which pyrolysis at temperatures above 400/sup 0/C exerts on the pore structure is to cause the micropores and transitional pores to grow, while leaving the macropores almost unchanged.
