✦ Synopsis

NMR spectroscopy.

Structural characterization by elemental analysis, FTIR, and NMR spectroscopy on both vacuum-distilled and air-blown pitches showed that distillation of lighter fractions, reduction of atomic H/C ratio, and dehydrogenation raised their softening points. Structural analysis by NMR showed that asphaltite pitches consist of condensed aromatic rings combined with methylene bridges and heterocyclic groups and substituted with alkyl and naphthenic groups. Aspbaltite pitches, which were prepared by solvent extraction (HI-BS) and vacuum distillation (AVD3), resulted in very good and medium spinnable green fibres, respectively. Scanning electron microscope analysis was used to study the morphology of the stabilized fibres. 00100236

This paper is part II in a series of two. Ash behaviour modelling of the gasi®cation of four biomass fuels is compared with pilot-scale experiments carried out in a pressurised ¯uidised bed gasi®er at the Royal Institute of Technology (KTH) and an atmospheric test rig of Termiska Processer AB (TPS).
