连续重整再生烧焦气中水对催化剂性能的影响

通过实验室模拟老化试验以及工业装置现场跟踪对比，考察了连续重整再生烧焦循环气中的水含量对催化剂性能的影响。结果表明：连续重整再生烧焦循环气中的水会造成催化剂比表面积下降以及载体孔径的增大，随着水含量的提高，催化剂的比表面积下降速率加快；随着催化剂比表面积下降，催化剂的持氯能力明显降低，催化剂的活性和选择性下降。

INFLUENCE OF H2O IN REGENERATION RECYCLE GAS ON PROPERTIES OF CONTINUOUS REFORMING CATALYST

Through simulation aging test in laboratory scale and the industrial device tracking, the influence of H2O content in the regeneration recycle gas on the properties of continuous reforming catalyst was investigated. The results show that the H2O in recycle gas can cause the loss of specific surface area of the catalyst and the increase of the pore diameter of the carrier. The increase of H2O content causes the fast reduction of the specific surface area of the catalyst, resulting in the obvious drop of the chloride retention capability, as well as the reduction of the activity and selectivity of the catalyst.
