| 摘 要： | 以微孔HY浆液为母液，合成了介-微孔复合分子筛HY/MCM-41。通过XRD、BET和NH3-TPD等手段对复合分子筛进行表征，并考察其水热稳定性。结果表明，复合分子筛同时具有中孔分子筛MCM-41和微孔HY型沸石的特点，与纯MCM-41分子筛相比，酸性明显增强，水热稳定性提高。利用一段串联加氢裂化工艺，考察了复合分子筛的催化性能。200 mL固定床加氢装置评价结果表明，在控制原料>350 ℃馏分油转化率为75%的条件下，加氢裂化生成油C5+液收98.51%，最大量柴油馏分［(140~370) ℃］收率69.09%，＜370 ℃中馏分油选择性80.5%，能满足工业装置最大量生产柴油的需要。

| Abstract: | A new meso- and microporous HY/MCM-41 composite molecular sieve was prepared using microporous HY zeolite as the mother liquor and characterized by XRD, BET and NH3-TPD， and its hydrothermal stability was also investigated. The results showed that the composite zeolite exhibited the properties of both mesoporous MCM-41 and microporous HY, with stronger acidity and higher hydrothermal stability than that of pure mesoporous MCM-41. Catalytic behaviors of the composite zeolite were investigated on a 200 mL fixed-bed hydrogenation apparatus, with C5+ liquid yield of 98.51wt％, diesel distillate yield of 69.09wt％ and selectivity to middle distillates of 80.5％ under controlled >350 ℃ feed distillate conversion of 75％，which met the requirement on maximum diesel distillate yield in oil refinery. |
