Temperature Programmed and Thermostatic Desorption of Toluene Laden Activated Carbon by Microwave Radiation
By microwave heating,thermostatic desorption and temperature programmed desorption of activated carbon with toluene was studied. Operation parameters were temperature 400℃ for thermostatic while for temperature programmed,initial temperature was 100℃,and the temperature was added 10℃ every 10min,final temperature was 500℃ with holding time of 5min. Results indicated that for thermostatic desorption and temperature programmed desorption,the highest concentration of desorbed toluene was 56.7g/m3 and 28.7g/m3 respectively,which can both make more than 90% desorption efficiency in 45min. Energy consumption for the two methods were analyzed,result indicated that compared with thermostatic desorption at 400℃,the energy consumption of temperature programmed desorption can be reduced by 23.7%.
