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.
Highlights
The quest for viable and affordable bio-blendstocks has led researchers to explore the potential of lignin-based compounds for the production of alternative fuels
The effect of the addition of ortho-cresol on the ignition delays of iso-octane/orthocresol blends is displayed in Figure 2 at two different compressed temperatures TC = 686 and 850 K
At TC = 850 K, the experiments show little to no effect of ortho-cresol addition on the ignition delays, while the model predicts a large increase in the Ignition Delay Times (IDT)
Summary
The quest for viable and affordable bio-blendstocks has led researchers to explore the potential of lignin-based compounds for the production of alternative fuels. Is ortho-Cresol a Viable alternative fuels have strong requirements for compliance with existing spark-ignition. A Kinetic engine technologies, among which sufficient resistance to engine knock. Study of Its Co-Oxidation within a Surrogate Fuel. Lignin is a cheap source of species in the structure of which the presence of an aromatic ring is often viewed as a guarantee of strong anti-knock behavior
