The distributed-energy chain model (DISCHAIN) interprets coal devolatilization in terms of independent influences from chemical reaction rates and from macromolecular configuration. Coal is represented by three components: (1) aromatic units that are attached pairwise by (2) labile bridges to form n

Predictions from the Distributed-Energy Chain Model (DISCHAIN) are compared with transient volatiles yields for heating rates between 103 and 105K/s and ultimate temperatures between 1000 and 2100K. All model parameters were assigned by correlating transient volatiles yields for much lower heating r

The Distributed-Energy Chain Model (DISCHA1N) is formulated in a companion paper [1]. In this paper, numerical predictions are compared to the transient weight loss from a bituminous coal in vacuum during heatup and throughout isothermal pyrolysis for two heating rates ( 102, 103K/s) at temperatures
