Reaction mechanisms have been proposed for the formation of major intermediates (C2H4 and CH2O) and final products (CO and CO2) from where it is revealed that intermediates are mainly consumed by the build-up of hydroxyl and hydroperoxyl radicals. Aromatic structures are the backbone of solid fuels such as coal and biomass. Methane is an ideal alternative to other fossil fuels but requires great bond strength to bond dissociation, which leads to poor ignition performance.

In addition, the reactivity of H2O is largely determined by the specific conditions such as temperature, H2O concentration and so on [17]. Donec aliquet. Moreover, the contribution of H atoms in the formation of H2 also indicates the variation in the proportion of steam reforming. Since the experiments are difficult to perform at the supercritical region, in this study, we demonstrate the capability of ReaxFF reactive force field method simulations to study combustion kinetics of fuels and fuel mixtures at these conditions with an objective to investigate how the presence of a highly reactive fuel can alter the properties of a much less reactive fuel during pyrolysis. For Free. Web.docx .docx.docx33 As we can observe by their oxidation state which is as follows: As we can observe carbon has an oxidation state of -4 in methane and it is oxidizing to an oxidation state of +4, similarly, the oxygen has an oxidizing state of 0 in its gaseous state while after reaction it gets reduced to -2. a molestie consequat, ultrices ac magna.

Among those, one promising option is oxy-fuel combustion, which involves the combustion of the fuel with pure oxygen and recycled flue gases instead of air as in traditional combustion. The main products observed in our simulations include H2O2, H2O, CH2O, and CO2.
