  • Subject: wood pyrolytic tar, calorific value

A sample of industrial wood pyrolytic tar was separated by vacuum distillation into volatile products and pitch. The highest heating value (HHV) was determined by bomb calorimetry for condensed volatile products (summary oils) and for pitch. For summary oils the HHV was found to be 28 800 kJ∙kg -1, which can characterize these products as a fuel with high energy density.

    1. The volatile fraction of industrial birch wood pyrolytic tar possesses high heating value of 28 800 kJ kg-1.

    2. Experimental heats of combustion are found to be consistently higher than those predicted by the empirical equations of Dulong and Mendeleev based on elemental composition.

    3. By comparison of 1H NMR spectra for initial tar and the summary oils it was concluded that distillation the summary oils fraction enriches the aromatics by about two times.
