摘要: Abstract Coal chars employed in the previous studies were usually prepared from coal pyrolysis at high temperatures and then cooled down to room temperature. As these burned out, they had undergone an additional process: cooling reheating. The influence of this process on conversion char-N nitrogen oxides mostly been neglected. In paper, reheating during NO N 2 O is studied a drop tube/fixed bed reactor. Results indicate that can cause fall emission char combustion. discrepancy between experiments with without low greater than temperatures. For rank sample, difference be up 20% temperature range 973–1073 K. addition, discrepant nitrogen, which would have converted into reheating, does not retain Most oxidized through reduction NO.
