摘要：
This study experimentally examines the effect of the addition of mixed gas (C2H6 + C2H4): (CO + H-2)=1:5 on the explosion characteristics of methane (volume fractions of 7%, 9.5%, and 11%) The explosion pressure, rate of increase in explosion pressure and time to reach the maximum explosion pressure are monitored. The mole fraction of radicals, sensitivity of CH4, and rate of production (ROP) are then calculated. The results show that the addition of mixed gas has the greatest impact on the explosion characteristics of the 7% methane mixture. For methane mixture of 7%, 9.5% and 11%, R1, R107 and R104, respectively, have the greatest impact on the methane sensitivity. The impact on the methane sensitivity in descending order is 7% > 9.5% > 11%. R1 (H + O-2=O + OH) was the most promoting and primary reaction for the consumption of O-2 and the production of OH.(c) 2023 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
