Abstract
A study has been made of the influence of pyrolysis temperature on the surface area and porosity of carbonized samples prepared by heating olive tree wood in flowing N2 (100 cm3, min−1) at different temperatures (473, 573, 673, 773, 873, 973, 1073, 1173 and 1273 K using a heating rate of 5 K per min). At temperatures above 723 K carbon is produced. The adsorptive properties of the samples have been determined by N2 adsorption of 77 K. Meso and macroporosity have been followed by mercury porosimetry. Surface area was found to increase up to 873 K, and thereafter to remain practically constant to 1173 K. The average pore diameter was not influenced.Keywords
