The kinetics of the catalytic combustion of benzene at different concentrations over the NiMnO3/CeO2/Cordierite catalyst were investigated to gain more insight into the catalytic reaction mechanism. A kinetic study was performed in a packed-bed tubular reactor under different conditions. The catalytic ...
Crafts, who discovered this reaction at the Sorbonne in 1877. Further substitution is possible, and under certain circumstances all six hydrogen atoms of benzene are capable of being replaced. The products of electrophilic aromatic substitution in benzene and its derivatives are employed in subsequent ...
What are Combustion Reactions? - A combustion reaction is a chemical reaction which a fuel undergoes oxidation by reacting with an oxidising agent, resulting in the release of energy (usually in the form of heat).
The combustion reaction characteristics in the nitridation of Si was investigated by measuring the combustion velocity (in the propagation process) and the combustion temperature. Silicon powder mixed with proper amount of Si{sub 3}N{sub 4}, which was added to produce a uniform and steady-state ...
However, to resolve the formulation challenge completely, the influence of the various chemical structures comprising a real fuel, and their interdependent combustion chemical reaction mechanisms must be prescribed. Here, at high temperatures, we should note that the variability among real fuels in ...

The combustion synthesis at normal pressure of aluminium nitride in a solid inert diluent (alumina, silicon carbide and aluminium nitride) was studied by thermogravimetric analysis. Using optical and scanning electron microscopy, it was observed that the morphology of the reaction products depended upon...
The value of enthalpy (or internal energy) of reaction for a fuel applies to complete combustion of that fuel to carbon dioxide and water. However, if the mixture is a rich one then there will be insufficient oxidant to convert all the fuel to CO2 and H2O, and it will be assumed here...
For example, the reaction for the combustion of liquid octane with Y % theoretical air is C8H18+(Y/100)12.5[O2+3.76(N2)]→8(CO2)+9(H2O)+(Y/100−1)O2+47(Y/100)(N2) To simplify matters, assume that, before the combustion, the reactants are at the SRS. Then, h¯(TR) =...
