Measurements of porosity and of reactivity to CO? have been made on chars by pyrolyzing three British bituminous coals of medium rank (Markham Main, Manvers Barnborough, and Manvers Wath). The porosity measurements were made by gravimetric adsorption of CO, at 195 K. Resulting isotherms were analyse

Predictions obtained by using the accepted reaction model together with three different reactor models -plug-flow, complete-mixing and bubble-assemblage -are compared. In general, the three reactor models gave significantly different results. The bubbleassemblage model, therefore, represents a valid
