| Outline of Final Research Achievements |
Oxy-fuel combustion technology is an emerging approach to capture post combustion CO2. In this technique, fuel is burned using a mixture of high-purity oxygen and recycled flue gas. In this study, clean coal technologies using the feature of oxy-fuel combustion were developed. It was shown that O2/CO2 environments were suited to reduce soot due to the CO2 reactivity (CO2 + H → CO + OH). Moreover, Char gasification in mixtures of O2 and CO2 was also discussed. A sufficient active site, mainly consisting of catalyst in this study, was important not only to enhance char gasification reactions but also to prevent competitive reactions between char-O2 and CO2 gasification.
