Reaction Kinetics of Some Carbonaceous Materials with Oxidizing Gas

Abstract

In order to get a highly reactive carbonaceous material at low temperature, the reaction kinetics of various carbonaceous materials with different structure was investigated. The reaction rate was the largest for Bintyo char and bamboo char on unit mass base, but it was the largest for graphite on unit area base. The rate had a positive relation with the amount of CO adsorption, showing that the rate determining step would be the desorption of CO from the active site on the surface. The rate independent of surface area was derived from the data of the rate and amount of CO adsorption per unit area.
