Understanding and operational assessment of the knock behavior environmentally friendly gas engine fuels is very important for expanding their practical application. Recent studies autoignition hydrogen methane at temperatures typical this process in internal combustion engines (800<T<1000 K) have shown that near 900 K, fundamental changes occur mechanisms oxidation associated with a change role peroxide compounds them. This leads to abrupt dependence mixtures containing them on...
Growing concern about climate processes has caused an interest in low-carbon fuels, such as methane and hydrogen. Although hydrogen seems to be beyond comparison this regard, the need for high energy consumption its production—mainly due same fossil hydrocarbons, low specific volume energy, problems with storage transportation—make production “hydrogen energy” chain extremely expensive, even environmentally unattractive. Estimates show that it is significantly inferior methane-based not only...
In the range of 800–1200 K, both experiments and kinetic modeling demonstrate a significant difference in dependence ignition delay time methane hydrogen on pressure temperature, with complex influence these parameters autoignition methane–hydrogen–air mixtures. connection prospects for widespread use methane–hydrogen mixtures energy production transport, detailed analysis their at temperatures below 1000 most important region from point view practical application, is carried out. It shown...
The potential wide use of environmentally friendly low-carbon gas fuel based on natural gas, hydrogen, their mixtures, and syngas in power generation transport requires detailed information about the kinetics ignition these gases at temperatures below 1000 K, which occurs internal combustion engines (ICEs) turbines. same temperature range is also important for monitoring storage transportation conditions fuels. Although there are quite a few studies addressing classical fuels such as methane...

The growing interest in the use of low-carbon fuels transport and energy sectors, primarily hydrogen, natural gas their mixtures, requires adequate methods for determining knock resistance. paper reviews some recently revealed features ignition these gases at temperatures corresponding to internal combustion engines (800 < T 1000 K). In this range, mechanisms hydrogen methane oxidation alters due a change role processes involving peroxide H2O2 hydroperoxide radicals HO2•. possibility sharp...
The presence of high concentrations heavy methane homologues with a low detonation resistance makes associated petroleum gases (APG) unsuitable for direct use as fuel gas piston engines, which constitute the basis distributed power generation grids in range up to 5 MW. One most informative and demonstrative parameters that determine characteristics mixtures is self-ignition delay time. At present, there are no systematic data on times even binary its heavier homologues, not mention more...
A variety of natural and anthropogenic sources hydrocarbon gases make a significant contribution to the global emission greenhouse gases. Reducing industrial is impossible without new technologies that would allow their cost-effective utilization. The paper describes number promising based on autothermal gas-phase processes partial oxidation oxidative cracking various hydrocarbons, such as associated petroleum gases, coalbed methane, refinery biogas, which open up prospects for reduction in...
