This paper evaluates the influence of crude oil (vacuum residue) properties, processing fluid catalytic cracking slurry oil, and recycle hydrocracked vacuum residue diluted with heavy cycle operating conditions H-Oil hydrocracking on quality liquid products. 36 cases operation a commercial H-Oil® ebullated bed hydrocracker were studied at different feed composition, conditions. Intercriteria an...

A series of MnOx-CeO₂ and MnOx-TiO₂ catalysts were prepared by a homogeneous precipitation method and their catalytic activities for the NO oxidation in the absence or presence of SO₂ were evaluated. Results show that the optimal molar ratio of Mn/Ce and Mn/Ti are 0.7 and 0.5, respectively. The MnOx-CeO₂ catalyst exhibits higher catalytic activity and better resistance to SO₂ poisoning than the...

Direct alcohol fuel cells (DAFCs) are a type of electrochemical energy conversion device that directly Convert the chemical energy stored in a liquid alcohol fuel, commonly methanol and ethanol, and also ethylene glycol, or npropanol, to electricity. Because of their simplicity, high energy density, instantaneous recharging, and presumably long life, DAFCs have been identified as the most promi...

The dirhodium(II) catalyst Rh2(esp)2 allows direct solvent-free allylic and benzylic oxidations by T-HYDRO with a remarkably low catalyst loading. This method is operationally simple and scalable at ambient temperature without the use of any additives. The high catalyst stability in these reactions may be attributed to a dirhodium(II,II) catalyst resting state, which is less prone to decomposit...

Hydrogenation of benzoic acid using monoand bimetallic catalyst of Ru, Pd, Co, and Re yielded different products. It was observed that 5% Ru/C was an active catalyst for hydrogenation of both aromatic ring and carboxylic group, while Pd/C catalyst hydrogenated only aromatic ring. Ru-Sn/Al2O3 is a chemoselective catalyst for hydrogenation of –COOH group of benzoic acid.
