Özet

Tuncbilek lignite and Denizli peat and several peat-lignite blends were pyrolyzed in a thermobalance apparatus at atmospheric pressure. Experiments were carried out dynamically by increasing the temperature from 25 degrees C to 900 degrees C with a heating rate of 20 degrees C/min under an argon atmosphere. Differential thermogravimetric data were analyzed by a reaction rate model assuming first-order kinetics. Effect of blending ratio of peat and lignite on the pyrolysis kinetics was investigated. Kinetic parameters were determined and the results was discussed. (C) 1999 Elsevier Science B.V. All rights reserved.
