Catalytic hydrocracking of phenanthrene over NiMo/Al2O3, CoMo/Al2O3 catalysts and metal-loaded Y-zeolites.

Fuel Formulation Studies

“…By creating a mixture of the two resids, a more optimal situation is created. This phenomenon has also been noted by other researchers working on the coking of blends of different oil feedstocks in the absence of coal [133,134]. The H/C ratios of the liquid products are shown in Table 21.…”

Selective Hydrocracking Polyaromatics into Light Aromatics: the Separation of Hydrogenation Center and Cracking Center

“…It revealed that Ni/HY catalyst presented more effective to convert polyaromatics than the NiMo and CoMo catalysts supported on aluminum oxide. 14 Lee et al reported that the Ni 2 P/Beta showed higher BTX yield of 94.4% than ZSM-5 and USY zeolites. 15 As for active metals, the noble hydrocracking catalyst loaded on Pt or Pd metals might exhibit high hydrogenation activities of polyaromatics than those conventional catalysts loaded on non noble metals including Co−Mo, Ni−W and Ni−Mo.…”

“…Song et al compared the phenanthrene hydrocracking behaviors of serial catalysts supported on HY zeolites and aluminum oxide. It revealed that Ni/HY catalyst presented more effective to convert polyaromatics than the NiMo and CoMo catalysts supported on aluminum oxide . Lee et al reported that the Ni 2 P/Beta showed higher BTX yield of 94.4% than ZSM-5 and USY zeolites …”

Oriented Hydrocracking of Naphthalene into High-Value Light Aromatics over Difunctional Catalysts: Effect of Hydrogen Spillover and Utilization of Hydroreaction Characteristics for Different Active Metals

“…The results showed that the Ni/HY catalyst was the most effective one to obtain aromatics with one ring and two rings, whereas the NiMo/Al 2 O 3 and CoMo/Al 2 O 3 catalysts could only yield hydrogenated phenanthrenes. 1 Youngseok reported the LCO hydrocracking performances on different hydrotreating catalysts loaded with different groups of active metals. It was shown that the yields of benzene, toluene, and xylene (BTX) for the NiMo catalyst were the highest.…”

“…Song et al investigated the phenanthrene hydrocracking performances over catalysts supported on HY zeolites and Al 2 O 3 and loaded with metals including La, Ni, and Fe. The results showed that the Ni/HY catalyst was the most effective one to obtain aromatics with one ring and two rings, whereas the NiMo/Al 2 O 3 and CoMo/Al 2 O 3 catalysts could only yield hydrogenated phenanthrenes . Youngseok reported the LCO hydrocracking performances on different hydrotreating catalysts loaded with different groups of active metals.…”
