In this program we are measuring the CO{sub 2}/CO ratio for both catalyzed and uncatalyzed chars over a wide range of temperature. These results will then be used to develop predictive models for char temperature and burning rates. In this report progress on modeling particle temperature under conditions where ignition occurs is reported. A comparison of preliminary modeling results with experimental results is also reported. 11 refs., 4 figs.
