Kinetics of coal drying decomposition Studocu

The initial reaction rates for oxidizing the coals at 150°C were approximately 4, 6 and 8 g Oz/kg coalh for drying temperatures of 150,225 and 300"C, respectively. A portion of this additionally consumed oxygen produces more COZ and CO. In fact, the coal drying tem perature determines whether or not CO is produced in measurable quantities.
