The Boudouard-Bell reaction analysis under high pressure conditions

A new method for the measurement of solid fuel reactivity towards carbon dioxide has been developed. This new method takes into account high-pressure and temperature effects. Three devolatilized carbonaceous materials have been used in experiments: chars derived from lignite, bituminous coal and blast furnace coke. Processes were carried out at temperatures of 800, 850 and 900 A degrees C and pressures of 1.52, 2.5 and 3.4 MPa. Analysis of the product gas composition was carried out with the maximum degree of conversion of CO2 (alpha(m)) proposed as a representative reactivity parameter. Arrhenius and Eyring relationships have been analyzed, and values of the activation energy and activation volume have been calculated.
