摘　　要：对经过烟气脱硫、脱氮吸附运转的FCC催化剂的烃油裂化微反性能进行考察,研究其再用作FCC催化剂的可行性。以轻油和正十六烷为原料的微反活性评价结果表明,经烟气脱硫、脱氮吸附运转后催化剂的活性与对比剂持平或略有提高。以大庆VGO为原料、主含MLC-500的复合剂为催化剂在ACE装置上的评价结果表明,当复合剂中经烟气脱硫、脱氮吸附运转后催化剂的质量分数在5%～10%的范围内时,其含量越高,烃油转化率越高,结焦率也越高,但焦炭/转化率增幅较对比新鲜剂减少50%左右。The micro activity of FCC catalyst used as adsorbent for removing SOx and NOx in flue gas （adsorbent-catalyst）was evaluated using light diesel distillate and n-hexadeeane as feeds respectively,and the feasibility of reuse said adsorbent-catalyst in FCC unit was discussed. Test results showed that the micro activities of used adsorbent-catalysts were equal or even a bit higher thanthose of the reference catalysts. Further evaluation was performed on ACE unit using VGO feed and composite catalyst based on catalyst MLC-500. Results showed that within a mass fraction of used adsorbent-catalyst in the range of 5% to 10% ,the feed conversion and coke yield increased with the increase of adsorbent-catalyst amount,yet the increment of coke selectivity was just half of that of the fresh catalyst.
