ABSTRACT

Reduction of N₂O by chars from subbituminous Siersza, Piast and Janina coals have been studied in a pressurised reactor at 973 – 1173 K. It has been found that the reaction N₂O + [C] → N₂ + [CO] is controlled both by the chemical kinetics and diffusion of N₂O within char particle’s pores. The rate constant of the above reaction has been found to be independent of pressure within the examined range of 0.2 – 1.0 MPa.

Keywords: pressurised combustion modelling, N₂O reduction
