Understanding the synergistic blending octane behavior of 2-methylfuran

The autoignition kinetics of hydrocarbons is an important criterion for selecting fuels piston reciprocating engines, and it can be determined by relative performance to mixtures alkanes, n-heptane iso-octane, under certain standardized operating conditions. 2-methylfuran a potential biofuel candidate, whose chemistry markedly different from alkanes. Its octane behavior when blended with paraffins also shows marked difference. blending fuel characterized its Blending Octane Number (BON). BON was extensively in this work. 2-methylfuran's mapped experimental ignition delay times measured constant volume combustion chamber using established correlations. effect on studied depending the RON base into which blended, as well quantity blended. 2-methyfuran greater than factor four or more some blends studied. reduced increasing fuel, A chemical kinetic model created integration validated sub-models blend components, then used explain leading extremely high values 2-methylfuran. synergetic anti-knock partially due physical properties molar fraction per compared iso-octane. Analysis revealed that action behind ability quench OH radicals are low-temperature oxidation This quenching achieved rapid reaction rate radical followed immediate conversion adduct shifting equilibrium towards product.
