Kinetic characteristics of sludge pyrolysis by the electric thermal furnace
Volume reduction and recovery as resources are the goal of waste disposal. This study investigated the kinetic reaction and the characteristics of the exhaust gases from incineration of a petrochemical sludge in an oxygen free environment. Sludge samples were pre-dried in an oven at 105 C for 24 hrs, result indicated 68% of the weight became water and volatile compounds, and the rest 32 % became drying sludge. Volatile organic compounds were generated from the sludge at 400 to 900 C, furthermore, it displayed a significant decomposition at 900 C. The volatile sulfur compounds were also generated and results denoted they were decomposed when pyrolysis temperature was excess 700 C. The reaction rate of the pyrolysis ranged from 1.5 x 10{sup {minus}3} to 1.47 x 10{sup {minus}1} sec{sup {minus}1} when the pyrolytic temperature ranged from 200 to 900 C. The average reaction order was 2.5. Results demonstrated the slope of activation energy (Ea/R) and frequent factor was 3,243 and 0.99 sec{sup {minus}1}, respectively.
