摘要
在对氧微分的流动式固定床反应器中,于1—25kPa 不同氧分压条件下,对525℃下重整催化剂和对630℃下催化裂化催化剂进行烧炭动力学研究,模拟出的动力学方程表明,重整催化剂上不同类型焦炭的燃烧速度与氧分压成0.55级关系,而催化裂化催化剂上焦炭燃烧速度与氧分压成0.75级关系。
Kinetics of coke combustion was investigated at 525℃ for Pt-Sn reformi-ng catalysts and 630℃ for cracking catalyst at constant oxygen partial pre-ssures from 1 to 25 kPa in a fixed bed reactor.The kinetic mathematicalequation simulated indicates that the combustion rate of different types ofcoke on the refo rming catalysts is 0.55 order to oxygen partial pressure and0.75 order for the coke on cracking catalyst.
