A test of the parallel reaction model using kinetic measurements on hydrous pyrolysis residues

Open-system kinetics are measured on extracted residues from hydrous pyrolysis to test aspects of the parallel reaction model and the assumption of a single frequency factor for all energies. The absolute rates of the residues form a series supporting the concept that the hydrous pyrolysis primarily removes the more reactive components at lower temperature. The parallel reaction model works well for the kerogen except for the highest temperature residue, which is a small amount of refractory material not adequately represented in the initial kinetics. The kinetic parameters derived from the unreacted coal predict too much remaining reactive material. The discrepancy may be due either to a weakness in the parallel reaction model or the fact that the open-system kinetics are not intended to predict the generation and subsequent removal of extractable organic matter. The constant frequency factor approximation works fairly well. The frequency factor shifts about ten-fold over the activation energy range in the kerogen and about 100-fold the activation energy range in the coals.
