The kinetics of vapor phase cracking of bitumen derived heavy gas oil and the quality of liquid products were investigated at temperatures of 600-700 °C. Fixed and condensed gases were analyzed by gas chromatography. The quality of liquid products was characterized using simulated distillation, elemental analysis and 13C NMR. Consistent with gas phase cracking behavior, the coke yields were negligible, below 2 %.
