Abstract:
Wheat straw activated biochar prepared by the microwave heating was used as the adsorbent in this study, with generation rate above 99% a comparison of microwave and conductive heating methods on heating time, generation rate and energy consumption for the regeneration of toluene from wheat straw activated biochar was conducted. Experimental results show that the adsorption capacity is unchanged(33%)compared with original wheat straw activated biochar for both microwave and conductive heating over 5 cycles. Microwave heating with constant power consumes the shortest heating time of 1 min for toluene, while the time for microware heating with constant temperature and conductive heating is 10 min and 120 min respectively. The energy consumption of microwave heating with constant power of 600 W and constant temperature of 150 ℃ is only 4.5 kJ/g and 9.0 kJ/g respectively but 36 kJ/g for conductive heating method. The microwave heating method could be an energy-efficient, resourceful and efficient regeneration technique for wheat straw activated biochar. 4 tabs, 3 figs, 11 refs.
