Fig. 1. Experimental (symbols) and simulations (lines) of the oxidative pyrolysis of neat and blended A2-C1 fuels in the flow reactor (Operating conditions: average initial fuel mole fraction of 310 (±5) PPM in a vitiated oxygen-nitrogen mixture at unity equivalence ratio and temperature of 1030 K. 20A2-80C1 designates 20-unit volume A2 blended with 80-unit volume of C1). For the simulation, the initial species concentrations of all the mixtures (at 3 ms) are taken from the measured values with the missing carbon lumped into the fuel proportionally. The initial species concentrations, including those from the vitiated mixture, are given in Table S4 of Ref. [1].

Fig. 2. Experimental (symbols) and simulations (lines) of the oxidative pyrolysis of neat and blended A2-C1 fuels in the flow reactor (Operating conditions: average initial fuel mole fraction of 606 PPM in a vitiated oxygen-nitrogen mixture at equivalence ratio of 2 and temperature of 1030 K. For the simulation, the initial species concentrations of the 80A2-20C1 and 50A2-50C1 mixtures (at 3 ms) are taken from the measured values with the missing carbon lumped into the fuel proportionally; and those of the 20A2-80C1 mixture are directly taken from the measured values. The initial species concentrations, including those from the vitiated mixture, are given in Table S4 of Ref. [1].
