An Empirical Correlation to Predict the Ignition Delay Time for Some Hydrocarbon Fuels [PDF]

Iranian Journal of Chemical Engineering, 2016
Examination of the available ignition delay time data and correlations in the case of methane, butane, heptane, decane, kerosene, Jet-A and ethylene fuels, allowed the derivation and recommendation of standard equations for this property.

Influence of high ethane content on natural gas ignition

Revista Ingenio, 2019
The effect of ethane on combustion and natural gas autoignition was studied in the present paper. Two fuel mixture of natural gas with high ethane content were considered, 75% CH4 – 25% C2H6 (mixture 1), and 50% CH4 – 50% C2H6 (mixture 2).
