By introducing gold nanoparticles, the classic Tollens reaction was re-explored for colorimetric measurement of formaldehyde.
Efficient dehydrogenation of cyclohexane at low temperatures is great importance in the field liquid organic hydrogen carriers (LOHCs). In this paper, a series Pt nanoparticles with size distribution 1.6–3.1 nm were loaded on nitrogen-doped carbon (Pt/CN) as catalysts for under (180–210 °C). The effect particle its catalytic performance was systematically explored. It found that volcanic trend exists between and activity dehydrogenation. conversion to benzene reaches up 96.03% 210 °C within...
This work presents an efficient approach for the primary separation of petroporphyrin component from asphaltene aggregates. The n-pentane asphaltenes separated vacuum residue Canadian oil sands bitumen were used as feedstock. release behavior petroporphyrins feed in polar solvents with assistance microwave irradiation was investigated. UV–vis spectroscopy utilized to calculate efficiency (PRE). effects concentrations and solvent properties on PRE discussed. Results show that, under...
Abstract Temperature and pressure effects on the catalytic performance of metalloporphyrins (MPs) for naphthalene hydrogenation were studied. Naphthalene over MPs sulfur (S), or S alone was examined at varying temperatures pressures. showed activity by aid S. The promoted increasing temperature. promotion nickel porphyrinseemed stronger than that vanadyl porphyrin. Excessive temperature hindered due to coke formation. To reveal role in MPs, demetalation traced ultraviolet‐visible(UV/Vis)...
Partial hydrogenation of anthracene under CO-H2O, N2-H2O, and H2-H2O over Fe-based catalysts was studied at 400 °C 10 MPa. Results show that the display obvious catalytic activity for CO-H2O instead N2-H2O H2-H2O. The follows in order Fe(NO3)3·9H2O > Fe naphthenate FeSO4·7H2O. Even though amount molecular hydrogen remains higher than situ hydrogen, conversion with is remarkably higher. It demonstrates more active PAH hydrogenation. To further reveal exact fate these catalysts, decomposed...
Efficient dehydrogenation of cycloalkanes under mild conditions is the key to large-scale application as a hydrogen storage medium. In this paper, series active metals loaded on nitrogen-doped carbon (M/CN, M = Pt, Pd, Ir, Rh, Au, Ru, Ag, Ni, Cu) were prepared learn role in cycloalkane with cyclohexane model reactant. Only Pt/CN, Pd/CN, Rh/CN and Ir/CN can catalyze set conditions. Among them, Pt/CN exhibited best catalytic activity TOF value 269.32 h-1 at 180 °C, followed by successively....
Petroleum residues with varying cutting depth and corresponding vacuum distillates have been prepared from laboratory deep-vacuum fractionation using unconventional heavy oil (UHO) originated Venezuela first. They are then sequentially characterized by general analysis, process pyrolysis analysis thermogravimetric (TGA), derivative (DTG), differential scanning calorimetry (DSC). Results indicate that a greater increase in recovery would be expected the case of UHO than other referenced...
Abstract Hydrogenation of nickel octaethylporphyrin (Ni‐OEP) over dispersed MoS 2 catalysts was studied in a batch autoclave at relatively low temperatures ranging from 553 K to 593 K. In spite the transformation catalytic species, invariant rate constants are acceptable analyze kinetics given temperature range. It turns out that first hydrogenation Ni‐OEP is limiting step when present. With combined analysis XRD and XPS patterns, Ni species deposited on surface were determined. As much as...
