Study on catalysts for phenanthrene hydrocracking to BTX

Tongji University Chemistry, Shanghai 200092, China

摘要

摘要: 采用等体积浸渍法制备了Ni/ZSM-5、Ni/HY、Ni/Al₂O₃和Ni/USY四个系列Ni含量不同的催化剂,在固定床反应器中考察了四类催化剂对菲的加氢裂化制BTX反应的催化性能。借助BET、SEM、热重和差热分析对催化剂的形貌、比表面积、平均孔径及积炭情况进行了表征,结合其结果对催化剂性能进行了分析。结果表明,Ni/HY和Ni/USY催化剂中Ni含量为12%时性能最优,收率可达52%。Al₂O₃催化剂的最佳Ni含量为6%,该系催化剂初始性能尚可,但失活较快;ZSM-5型分子筛催化剂性能较差。

Abstract: 4 series of catalyst with different Ni loadings, including Ni/ZSM-5, Ni/HY, Ni/Al₂O₃ and Ni/USY,were prepared by volumetric immersion method. The catalytic performance of the prepared catalysts for phenanthrene hydrocracking was evaluated using a fixed bed reactor. BET and SEM were used to obtain the catalysts' phase structure, surface area and average pore size. The carbon deposition of catalysts after reaction were measured by TG/DSC. The results showed that 12% Ni loading on HY and USY zeolites had best catalytic activity for phenanthrene hydrocracking with the BTX yield of 52%. As to Ni/Al₂O₃ the best nickel loading was 6%, and this catalyst just had a good catalytic activity at beginning and deactivated quickly. Ni/ZSM-5 had poor catalytic activity.
