Abstract: Carbon dioxide emissions represent the main environmental issue characteristic to combustion processes. Therefore, any effort in this direction is justified by the benefits that result. The paper puts forward a CO2 abatement technique involving the enrichment in hydrogen gas of a gaseous fuel (natural gas). The original combustion calculus algorithm developed by the authors takes into account dissociation and its output consists of the flue gases temperature and composition in terms of mole fractions and volumes as well. Analysis of output data obtained for different fuel compositions in terms of H2 percentage shows that low CO2 flue gases result and thus the main hypothesis is confirmed. Other consequences are also considered and highlighted, confirming that fuel enrichment in H2 can represent a promising candidate for CO2 emissions abatement.
