微孔-介孔复合分子筛hy-sba-15的表征及应用
, PP. 732-736
Keywords: hy-sba-15,复合分子筛,柴油,表征
Abstract:
？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。
