Abstract: Abstract Peat bitumen obtained by solvent extraction of Irish high moor peat was subjected to chemical, structural and rheological characterisation. The bitumen was fractionated on the basis of solubility in n‐heptane, toluene and ethyl acetate into wax, resin and asphaltene; each of these major constituent groups was further separated into sub‐fractions by column chromatography using solvents of increasing polarity. All materials were chemically characterised by C, H, N and O content and infra‐red spectrosco…
