AN EXPERIMENTAL STUDY OF RECOVERABLE PRODUCTS FROM WASTE TIRE PYROLYSIS

In this study, potential of useful products recovery was investigated from waste tires that completed the physical life by virtue of pyrolysis process. Disposal of waste tires, which is one of the global environmental problems, continues the presence thereof as a serious problem, especially in developed countries. Pyrolysis and gasification processes stand out due to making possible the disposal of waste tires and obtaining products that can be employed in energy recovery. Pyrolysis experiments were carried out in a fixed-bed-reactor with cyclone separator at various temperatures (300 degrees C, 400 degrees C, 500 degrees C, 600 degrees C and 700 degrees C) and nitrogen, employed as agent gas, was given batch and continuously during the process. In the study, the calorific values of the liquid and solid pyrolysis products were determined as 9117 kcal m(-3) and 8710 kcal kg(-1) respectively. When the results of the experimental studies were evaluated, synthesis gas rich in CH4 and H-2 with a high calorific value of 4180 kcal m(-3) was achieved.
