VAPOUR PHASE CRACKING OF TAR FROM PYROLYSIS OF BIRCH WOOD

ABSTRACT
The vapour phase cracking of tar from pyrolysis of birch wood (particles, 0.5-1.0 mm) was studied in a thermogravimetric analyser (TGA) and in a coupling of the TGA with a consecutive tubular reactor. The TGA was heated from 100 to 1000°C at a heating rate of 5 K/min in all experiments and the tubular reactor was operated at constant temperatures of 600°C, 700°C and 800°C at different residence times. Kinetic parameters for tar cracking and yield coefficients for the production of different gases from tar cracking were calculated.
