Results on the low-temperature self-ignition of binary methane–Cn alkane mixtures have been previously obtained. In this work we extended the investigation to more complex multicomponent mixtures to check the additivity of different alkanes in promoting methane self-ignition. Besides, the possibility of obtaining certified gas fuel from typical OAG by selective oxidative conversion of heavy components in OAG was checked. Experimental results and detailed computer modeling of self-ignition delay coincide well. It was reviled, that the influence of all heavier alkanes on the self-ignition of methane is similar enough including the values of activation energies of self-ignition delay, although some abnormalities in C2-C5 series were noted. It allows hoping that it will be possible to describe this influence by some unified equation. If that, it will be significantly easier to estimate necessary degree of OAG cleaning and the efficiency of the used methods thus promoting more wide OAG utilization for power generation.
