Pyrolysis kinetics of blends of Tuncbilek lignite with Denizli peat

Tuncbilek lignite and Denizli peat and several peat-lignite blends were pyr olyzed in a thermobalance apparatus at atmospheric pressure. Experiments we re 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 atm osphere. Differential thermogravimetric data were analyzed by a reaction ra te model assuming first-order kinetics. Effect of blending ratio of peat an d lignite on the pyrolysis kinetics was investigated. Kinetic parameters we re determined and the results was discussed. (C) 1999 Elsevier Science B.V. All rights reserved.
