Identification of the starting reaction position in the hydrogenation of (N-ethyl)carbazole over Raney-Ni

Ultrasound-excited hydrogen radical from NiFe layered double hydroxide for preparation of ultrafine supported Ru nanocatalysts in hydrogen storage of N-ethylcarbazole

“…It is proved that the apparent reaction rate of NEC concentration is zero-order and that of hydrogen pressure is first-order in NEC hydrogenation [50] , [51] , [52] . The hydrogenation kinetic model can be expressed as: …”

Bimetallic Ru-Ni/TiO2 catalysts for hydrogenation of N-ethylcarbazole: Role of TiO2 crystal structure

“…Catalysts widely used in the hydrogenation process are Rubased [17,18] . There are also some other reports on Ni-based catalysts, while the performance is much inferior and thus very high metal loading is required to achieve reasonable hydrogenation efficiency [19][20][21][22] . Expensive Ru based hydrogenation catalyst is one of the major obstacles to achieve large scale application of NEC as a LOHC.…”

Hydrodenitrogenation Kinetics of Diesel Oil and Catalyst Stacking Simulation

“…14,15 The hydrogenation of aromatic rings is generally regarded as ring by ring. Sun et al 16 investigated the chemistry of (N-ethyl)carbazole hydrogenation over a Raney-Ni catalyst and proposed that the reaction was a stepwise hydrogenation process and the first H 2 was added to the C1C10 double bond in the hydrogenation. According to the literature, 17−19 piperidine.…”

“…For six- and five-membered N-ring nitrogen compounds, it is generally believed that the aromatic ring is saturated first and then the C–N bond is broken. , The hydrogenation of aromatic rings is generally regarded as ring by ring. Sun et al investigated the chemistry of ( N -ethyl)­carbazole hydrogenation over a Raney-Ni catalyst and proposed that the reaction was a stepwise hydrogenation process and the first H 2 was added to the C1C10 double bond in the hydrogenation. According to the literature, − pyridine was first hydrogenated and saturated with aromatic ring into piperidine.…”
