| 英文摘要 | An integrated fluidized bed (IFB) consisting of an upper transport bed section and a bottom fluidized bed section was adopted to investigate the transport bed coal pyrolysis by varying its reaction temperature and reaction atmosphere adjusted to simulate steam-containing syngas produced by the bottom fluidized bed char gasification. Steam and syngas, in comparison with N-2, as the reaction atmosphere little affected the tar yield below 600 degrees C but significantly decreased it for the former and increased it for the latter at rather higher temperatures. The presence of H-2 in the syngas increased tar yield significantly because it could suppress polymerization and condensation reactions through providing H as radical stabilizer and hydrogenation agent. In the steam-containing syngas atmosphere, the tar yield obtained from transport bed rapid pyrolysis increased rapidly with raising temperature to a peak value of 10.5 wt.% (daf) at 600 degrees C, about 1.1 wt.% higher than the Gray-King assay yield, and then decreased due to the excessive secondary reactions. Analyzing tar composition further showed that steam-containing syngas combined their respective advantages that syngas improved the yields of both light and heavy tars while steam reduced the heavy tar yield, especially at temperatures above 600 degrees C. The steam-containing syngas atmosphere also promoted CH4 production in comparison with syngas atmosphere below 700 degrees C. (C) 2016 Elsevier Ltd. All rights reserved. |
