Comparsion of Temperature-Programmed Char Combustion in CO_2-O_2 and Ar-O_2 Mixtures at Elevated pressure

摘要

In previous work the authors studied the temperature- programmed combustion of ocal chars by atmospheric- pressure thermogravimetry (TG) and found that the mass-loss rate did not depend on the CO_2 content of the ambient gas. Future combustion systems, however, may be based on combustion at high pressures with a larger concentration of CO_2 in the combustion environment. To study the role of OC_2 under pressurized conditions, we repeated the key experiments of our earlier work in a pressurized TG system.
