摘要:

 以甲基纤维素(MC)为辅助模板剂,制备了SBA-16介孔分子筛(SBA-16-MC),以该材料为载体制备了Ni/SBA-16-MC,用作以萘为探针的加氢脱芳反应的催化剂。对催化剂的晶相、形貌、比表面积、孔径等进行了表征,并评价了催化剂的催化性能。结果表明:MC的加入使Ni/SBA-16-MC具有比Ni/SBA-16更高的比表面积、孔容和更大的介孔孔径,SBA-16-MC上NiO与载体的作用变弱,NiO的还原温度降低。Ni/SBA-16-MC的催化活性和选择性均明显高于Ni/SBA-16,脱芳率高于91.0%,十氢萘选择性高于85.0%。

 SBA-16-MC mesoporous molecular sieve was firstly prepared with methyl cellulose (MC) as an auxiliary template, and then Ni/SBA-16-MC was prepared with SBA-16-MC mesoporous molecular sieve as a catalyst support. This catalyst can be used for the hydrodearomatization with naphthalene as a probe. The crystal phase composition, morphology, specific surface area, pore size of the catalysts were characterized, and the catalytic performance of the catalyst was evaluated. The results show that the introduction of MC can make Ni/SBA-16-MC have greater specific surface area, higher pore volume and larger mesoporous pore size than those of Ni/SBA-16. The interaction between NiO and SBA-16-MC becomes weaker and the reduction temperature decreases. The catalytic activity and selectivity of Ni/SBA-16-MC are greater than those of Ni/SBA-16. The dearomatization rate is > 91.0%, and the selectivity of decalin is >85.0%.
