摘要

摘要: 用后合成法制备了微孔-介孔复合分子筛HY-SBA-15(y) (y表示HY与SBA-15的质量比)。并用XRD、FT-IR、N₂吸脱附及NH₃-TPD等技术对HY-SBA-15进行表征。结果表明,HY-SBA-15既具有微孔结构又具有介孔结构,当y=0.10时,微孔与介孔混合晶相显著,且HY-SBA-15(0.10)复合分子筛具有B酸和L酸,酸性强于HY。用浸渍法将Ni-W活性组分担载在HY-SBA-15(0.10)载体上,制备加氢脱芳烃催化剂Ni-W/HY-SBA-15(0.10),选用茂名石化FCC柴油为原料,考察了催化剂的加氢脱芳烃性能。实验结果表明,Ni-W/HY-SBA-15(0.10)催化剂具有良好的芳烃加氢饱和性能和开环活性。

Abstract: A series of HY-SBA-15(y) composite molecular sieves (y denotes the weight ratio of HY to SBA-15) were prepared by post-synthesis method and characterized by XRD, FT-IR, N₂ sorption, and NH₃-TPD. Ni-W/HY-SBA-15(0.10) catalyst was then prepared by impregnating HY-SBA-15(0.10) with Ni-W solution and used in hydrodearomatization of Maoming FCC diesel oil. The results indicated that HY-SBA-15 has both HY microporous and SBA-15 mesoporous structure and the microporous and mesoporous structures of HY-SBA-15 match remarkably well when the value of y is 0.10. Both Bronsted acid sites and Lewis acid sites are present on the surface of the composite molecular sieve HY-SBA-15(0.10) and its acidity is stronger than that of HY zeolite. When loading Ni and W on it, the Ni-W/HY-SBA-15(0.10) catalyst exhibits high activity in the hydrodearomatization and opening of aromatic rings.
