Abstract

Hydrocarbon hot surface combustions initiate by oxygen radical anion Brönsted base electron pair proton abstraction, yielding carbanions and hydroxyl radicals, only then proceeding by electron transfer to form alkyl free radicals in conventional radical pathways. Successive positive/negative electrostatic field pulses facilitate oxygen radical anion formation from air by Seebeck electron transfer to the hot surface during positive phases. Higher reaction rates result by radical anion repulsion from surfaces during the negative phase. Industrially important oxidation reactions occur with higher rates and yields at lower temperatures. Reduced internal combustion engine fuel requirements, NOx and soot emissions result, with increased engine horsepower. Better Seebeck catalysts should result in optimized performance for commercial oxidations, and for engine performance.
