Abstract
In this study, pyrolysis process of beech wood was carried out a horizontal cylindrical reactor of stainless-steel, 127.0Â mm height, 17.0Â mm inner diameter and 25.0Â mm outer diameter inserted vertically into an electrically heated tubular furnace in the absence of oxygen in irregular heating rate conditions. The increases of the pyrolysis temperatures with time of pyrolysis are considerably irregular in the reaction conditions. From 60Â s to 90Â s period, the average heating rate is higher than 6Â K/s for the samples with â0.063Â mm, +0.060Â mm and +0.150Â mm. The average increase of temperature is slow from 170Â s to 350Â s period. The increase of temperature is highly regular in 450-600Â s periods. The completion time of pyrolysis decreases from â0.063Â mm to +0.150Â mm and then it increases with increasing size of particle. The lowest completion time and completion temperature for a +0.150Â mm particle size is 445Â s and 670Â K, respectively, in the reaction conditions. The increases of liquid yields are considerably sharply for all of the samples in 90-170Â s periods.
