“…Readers interested in the general aspects of soot formation are referred to the works of McEnally and Pfefferle [30], Richter et al [25], and Bockhorn [31]. Of greatest importance to the present study is the chemical effect of the addition of CO 2 to methane (which may be used to represent various compositions of bio-syngas and biogas [9], [10]) upon aromatic chemistry.…”

This numerical study concerns the effect of CO 2 addition to CH 4 on aromatic chemistry. In the absence of any thermodynamical effects, purely kinetic factors cause increases in the amount of carbon dioxide to decrease benzene mole fraction. The reaction H + CO 2 ⇋ OH + CO proved very important. Simulations under adiabatic conditions shows that raising the concentration of CO 2 leads to an increase in A 1 mole fractions. This is caused by CO 2 addition making the combustion less efficient, so that both the temperatures and the concentrations of the OH radical are lower than for pure methane. We also discovered that the CO 2 kinetics reduces the amount of benzene under isothermal conditions whereas it increases it under adiabatic conditions. Finally, we found that CO 2 addition to benzene has negligible kinetic effects on aromatic hydrocarbons, radicals and even CO. Overall, our study shows that the kinetic effects of carbon dioxide in biogas can be highly complex, non-linear and counter-intuitive.

“…It is made up of CO, CO 2 , CH 4 and H 2 and is considered to be a cleaner fuel than biogas due to its higher hydrogen content [8]. In three recent publications [9][10][11], we investigated the chemical kinetics of CH 4 -CO -H 2 -CO 2 fuel mixtures by using ignition delay times measured inside shock tubes.…”

“…pressure and temperature) and in fact, some mechanisms have a limitation in terms of the number of species. Similarly, 3 reaction mechanisms (GRI 3.0, DRM22 [18] and Heghes' C1-C4 [19]) seemed to be capable of computing a mixture of H2 flame with CH4, CO, CO2, H2 and H2O , since a good agreement with the experimental data was obtained from these mechanisms [20].…”

“…Biogas and bio-syngas are two alternative fuels that recently are in centre of attention [20]. Biogas is produced by fermentation of biomass by anaerobic bacteria and is mainly composed of CH 4 and CO 2 [6], whereas Bio syngas is a synthetic gas produced from the thermal gasification of biomass and composed from different proportions of CH 4 , H 2 , CO and CO 2 [5]. As it can be seen, for both gases, CH 4 and CO 2 are two common components.…”
