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
materials was studied in a crusher with a screening drum, and screening kinetics were studied with a drum classifier for various drum rotational speeds and two load-to-drum volume ratios.
