Abstract
General considerations of effects of chemical and physical parameters upon particle temperature profiles during coal pyrolysis are followed by a description of physical model developed for this study. The basic model proposed here for calculation purposes views coal as consisting of two ″fractions.″ - a pyrolytic fraction and an inert fraction. The ″pyrolytic″ fraction is taken to mean the thermally active or responsive material present in the coal matrix. The response is assumed to take the form of a first order expression of the Arrehenius type. The pyrolytic fraction exists uniformly throughout the particle. ″Inert″ is taken to mean the part of the coal matrix which is not subject to thermal decomposition but only to simple heat absorption. Other topics are presented under headings - numerical formulation and solution techniques; results and discussion.
