The complete electrochemical combustion of phenol has been found under 5 M at the carboxyl modified carbon nanotube electrode in phosphate buffer solution. The reaction was discussed in details. Due to the porous tubule of the structure of the carbon nanotube and large quantity of hydroxyl exists ...
One is the direct reaction of basic anions with acidic CO2 to form carbamate; The second is that the acidic C2-H in the imidazolium cation is removed by the basic anion to form carbene, which is combined with CO2 to form imidazole carboxylate, but the latter has low absorption and is ...
The shift technique yields an oxygen reaction order of 0.5, which decreases slightly with bum-off, and an activation energy of 120 KJmol−1, which increases slightly with burn-off. These values are found for the combustion of nine chars irrespective of their panicle sizes, ash content or ...
Input data used for training the network are the mixture fraction, and molar abundance of CO2, H, and H2O whereas the output represents the change in composition of the reactive scalars, CO2, H, and H2O, over a certain reaction time. The network showed good ability in capturing the general...
Oxygen-depleted conditions can reduce the heat release of coal, delaying the occurrence of characteristic temperature points and prolonging the reaction time29. Controlling the temperature of the coal pile during the self-heating period or below can prevent spontaneous combustion. Therefore, the ...
of various experimental data available in the literature,including shock tube tests and HCCI engine experiments,shows that the present TRF mechanism performs well.A sensitivity analysis at the moment of maximum heat production shows that the reaction of phenol radicals (C6H5) with O2 is more ...
In laser-ablation propulsion, an intense laser beam [pulsed or continuous wave (CW)] strikes onto a condensed-matter (solid or liquid) surface and produces a jet of vapor or plasma. Just as how it works in a chemical rocket, thrust is produced by the resulting reaction force on the ...
15. Raw coal contains more free –OH and associative –OH, and most of them appear in the form of associative structures [58]. The –OH is consumed and generated throughout the whole oxidation reaction, and the peak area of –OH decreases by 2.32% after the addition of XG/GG/HPAM gel...
