Effect of Process Conditions on the Yield of Pyrolytic Products From Southern Pine
Keywords:
Pyrolysis, southern pine, temperature, time, flow rate, product yieldsAbstract
Southern pine samples were subjected to temperatures of 250, 350, 400, 500, and 800 C for 1, 2, and 4 hours in an atmosphere of flowing nitrogen gas at two flow rates. Solid, liquid, and gaseous phases were produced, the yields of which were statistically analyzed and found to be dependent on the pyrolytic conditions. All product yields differed significantly with temperature, but no significant differences with regard to reaction times were detected.References
