초록

Since sewage sludge has low heating value as an energy source, it is desirable that sewage sludge is mixed with woodywaste to enhance energy potential. Among thermal methods for waste to energy, carbonization process is used in thisstudy. In order to estimate reaction kinetics for carbonization process using mixture of woody waste and sewage sludge,the content of sewage sludge is varied from 10 ~ 30% in mixture of woody waste and sewage sludge in carbonizationprocess. Carbonization time is changed from 10 min to 50 min and carbonization temperature is varied from 250oC to350oC. The carbonization process for mixture of woody waste and sewage sludge was optimized at carbonizationtemperature of 300oC for 20 min, 20% of sewage sludge content. As increased carbonization temperature, reaction rateconstant, frequency factor and degree of carbonization were increased. As increased the content of sewage sludge, conversion,ash content and degree of carbonization were decreased. At optimal conditions for carbonization process, frequency factorand activation energy in Arrhenius equation can be decided by 3.61 × 10−2 min−1, 7,101.8 kcal/kmol respectively.
