| 摘 要： | 在系统考察添加阳离子表面活性剂、凝胶陈化以及晶化温度和晶化时间等因素对NaY分子筛细化影响的基础上,对纳米NaY分子筛的合成规律进行了研究;合成出了n(SiO2)/n(Al2O3)=4.5,BET比表面积为620m2/g,孔容为0.34 cm3/g,微孔集中分布在0.55 nm附近,粒度分布范围在100 nm以内的纳米NaY分子筛.并采用XRD、BET、IR、TTEM和NH3-TPD等手段系统表征了纳米NaY分子筛的微观结构.分别采用合成的纳米NaY分子筛和微米NaY分子筛为原料制备负载型Ni-Mo-P催化剂,并以FCC柴油为原料,考察了催化剂的加氢改质性能,结果表明,与微米NaY分子筛基负载型Ni-Mo-P催化剂相比,纳米NaY分子筛基负载型Ni-Mo-P催化剂,在加氢脱氮率、密度和十六烷值相当的情况下,其加氢脱硫率较高,柴油收率较高.

| Abstract: | In this study,the effect of four factors on crystallite particles size of as-synthesized NaY zeolite was investigated,such as the addition of cationic surfactant,aging of the gel,crystallization temperature and crystallization time.The structure and surface characteristics of the as-synthesized nano-NaY zeolites were measured by XRD,BET,IR,NH3-TPD and TEM.The results showed that SiO2/Al2O3 ratio of the as-synthesized nano-NaY zeolites was 4.5,BET area was 620 m2/g,and the pore volume was 0.34 cm3/g,the micr... |
