“…Many researchers have published data relating to NO reduction on char and have computed kinetic rates for the reduction reaction (Chan et al, 1983;Levy et al, 1981;Song et al, 1981a;de Soete, 1990;Furusawa et al, 1980;Teng et al, 1992;Suuberg et al, 1990;Rodriguez-Mirasol et al, 1994). All of these researchers conducted their experiments in the absence of O 2 ; they fed mixtures of Ar/NO or He/NO over a bed of char and computed kinetic rates for the reduction reaction based on measurements of gas concentrations in the effluent.…”
