Soot oxidation kinetics. Final report, 1 August 1983-15 December 1987
Soot and carbon-black oxidation kinetics were measured under controlled temperature, pressure, and oxygen concentration, conditions in a modified High-Temperature Fast-Flow Reactor. The kinetic measurements are carried out under conditions where the carbon particle consumption rate is controlled by gas-particle interactions and not by mass transfer. Auxiliary surface-area measurements on partially oxidized particles collected from the HTFFR indicate that the oxidation is controlled by external-surface rather than pore-centered reactions. The measured particle reactivities (g cm/sup -2/ s/sup -1/) are x 10 smaller than predicted by the often-used Nagle-Strickland-Constable semi-empirical model for carbon oxidation nor do the O/sub 2/ dependences conform to this model. Additional work is required to elucidate the reasons for this disparity.
