Synfuels differ from petroleum fuels primarily in the amount of nitrogen and oxygenated species which they contain and in their aromatic content. The nitrogen and oxygen concentrations are in the range of 20-50 times larger in the synfuels; they are present as heterocyclic ring compounds and phenols. Coal-derived liquid fuels in the middle boiling distillate range are mainly single-ring aromatics; in the heavy boiling range, they are mainly 2- and 3-ring aromatics. These compositional variations have suggested that the tendency for sooting and NO /SUB X/ emissions of synfuels must be predictable under wide-range conditions and applications. This investigation relates important combustion characteristics, including efficiency and emissions of CO, soot and NO /SUB X/ to the properties of typical synfuel components. The approach is one involving the development of a quasiglobal kinetics model to represent the rate of fuel oxidation including the formation and decomposition of intermediate hydrocarbons, CO, NO /SUB X/ and soot. This kinetics model is designed to characterize fundamental combustion observations in such a manner that it can be used to help establish effective synfuels utilization criteria. The paper describes the methodology together with typical examples of its application.
