高积炭连续重整催化剂的烧焦与结焦分析

在实验室进行了连续重整装置死区高积炭催化剂的烧焦实验，同时对死区高积炭再生催化剂的物性进行了表征。结果表明：死区高积炭催化剂含有石墨炭；在低氧含量（体积分数为1.0%）的条件下，烧焦温度达到540 ℃以上时，死区催化剂上的积炭可以被引燃；在高氧含量（体积分数为21%）的条件下，烧焦温度为480 ℃时，死区催化剂上的积炭可以被烧尽。

COKE ANALYSIS AND COKE BURNING OF HIGH CARBON CONTENT HEEL CATALYST OF CCR

Coke burning of CCR heel catalyst with high carbon content was done in lab and the physical properties of the regenerated heel catalyst were characterized. The results show that the heel catalyst contains graphite carbon and the carbon on the dead zone catalyst can be ignited at 540℃ in low oxygen content (1.0v %) atmosphere, while the coke on the heel catalyst can be burned up at 480℃ in high oxygen content (21v %) atmosphere.
