Reaction of phenyl radicals with propyne.

The potential energy surface (PES) for the phenyl + propyne reaction, which might contribute to the growth of polycyclic aromatic hydrocarbons (PAHs) under a wide variety of reaction conditions, is described. The PES was characterized at the B3LYP-DFT/6-31G(d) and B3LYP-DFT/6-311+G(d,p) levels of theory. The energies of the entrance transition states, a direct hydrogen-transfer channel and two ...

Catalytic reduction of SO2 with CH4 to elemental sulfur: A comparative analysis of alumina, copper-alumina and nickel-alumina catalysts

The catalytic reduction of sulfur dioxide with methane to form elemental sulfur has been studied. Al2O3, Cu-Al2O3 and Ni-Al2O3 were examined as catalysts and their performances were compared in terms of SO2 conversion and selectivity. Performance of the catalyst extremely enhanced when nickel and copper were added as promoters. The effects of temperature, SO2/CH4 molar ratio, and reaction...

Optimization of the preparation procedure of Ni/Al2O3 catalyst for steam reforming of n-butane

Performance of Ni/Al2O3 catalysts (10 wt.% Ni) in steam reforming of n-butane was investigated in terms of n-butane conversion, selectivity to hydrogen and hydrogen yield. The process was carried out in a fixed-bed tubular reactor at 650 °C and atmospheric pressure. The volumetric flow rates of n-butane and steam were 0.1 mL/min and 0.6 mL/min, respectively. The catalysts were prepared by preci...
