A Novel Technique to Measure Kinetic Parameters of Pyrolysis and Gasification Reactions

Said Samih and Jamal Chaouki have recently published a research article in the Canadian Journal of Chemical Engineering. The developed Fluidized Bed Thermogravimetric Analyzer (FB-TGA) in PEARL group was employed to investigate the pyrolysis and gasification of coal. Syngas (a mixture of CO and H2) were produced from such complex feedstock, and novel kinetic parameters were predicted. Five grams of coal was gasified without observing a diffusion control step. In contrary to the conventional TGA, the thermocouple of the FB-TGA measured the direct temperature of the reaction in this work and, consequently, the temperature gradient was eliminated. This unique technique allows the development of novel kinetic parameters from the FB-TGA for both pyrolysis and gasification reactions.
