Degradation of benzo(a)pyrene in the presence of methanol in fuel in the temperature range of 150-300 °C

The degradation of benzo(a)pyrene (BaP) at the temperature of a cold spark-ignition engine (150-300 degrees C) has been determined under modelling conditions. The degradation degree of BaP in the M-85 ecological fuel both in the presence of the Pt(0.06%)Rh(0.012%) catalyst and without it surpasses, by several percent, the BaP degradation degree in fuel not containing methanol. In the presence of a catalyst the effectiveness of BaP degradation in the M-85 fuel increases decidedly within the studied temperature range. The presence of methanol in fuel positively influences the BaP degradation, which increases with a temperature rise.
