Abstract

Pyrolysis, as a first step in all thermochemical coal conversion processes, has been investigated in detail over the years in order to evaluate the kinetic data and to establish reliable models for the complex reaction scheme. Since coal pyrolysis is not a single reaction but rather a multiplicity in different time intervals for isothermal pyrolysis, or in different time and temperature intervals for the case of heat-up, any set of parameters cannot be expected to represent data accurately over a wide range of conditions.
