Abstract: The viability of the use of ortho -cresol as a bio-blendstock or antiknock additive from lignocellulosic biomass is assessed; Ignition delays of ortho -cresol within blends with iso -octane are measured with the ULille rapid compression machine, and compared with results from the literature; It is shown that ortho -cresol has a strong inhibiting effect on the reactivity towards ignition, most notably in the Negative Temperature Coefficient region; This effect is found to originate from competition with iso -octane on the OH radicals, where the reactivity of ortho -cresol with these radicals does not lead to radical chain-branching.
