In order to determine the total pyrolysis yield, another technique was used. Basically, the approach involves capturing the py-rolyzing coal particles in a crucible at the maximum residence distance in the reactor. The captured samples are then held in the reactor for 10 minutes to complete pyrolysis. It is thought that this technique gives a reasonable estimation of the total pyrolysis yield possible in an entrained flow reactor. The results of this study can be seen in Table V in which weight loss values for extended... 

Kinetics of Total Weight Loss. The method chosen is a simple first order Arrhenius treatment in which a single overall activation energy is utilized. The technique has been applied to the kinetics of the initial weight loss, and therefore, the weight loss values were compared to the maximum weight loss in the entrained flow reactor.
