In order to develop improved fuel particles, pyrohysis byproducts of both the pyrocarbon separated in fluidized beds and the resulting soot were studied. The aim was to study the separation mechanism of pyrocarbon on fuel kernels during the thermal decomposition of low hydrocarbons. This study referred to pyrolysis products of acetylene and propylene. The extraction was performed with various methods. The extracts were separated gas- chromatographically and mass-spectrometrically; the single components were partially identified. 21 polycyclic and aromatic hydrocarbons were clearly identified in soot. Beyond that, pyrocarbon contains still higher molecular pohycyclic compounds. (18 figures, 12 tables, 34 references) (auth)
