The dependence of microwave regeneration of activated carbon on time and temperature

摘要

Spent granular activate carbon(20 and 40/100 moisture wet basis)was regenerated at 750-850 deg. C for 5-30 minutes in an 850W, 2.45 GHz microwave oven. Microwave-regenerated carbon generally performed better than mine-regenerated carbon. After 5 minutes of regeneration, recommended in- dustrial performance levels(dimensionless activity > 0.7, loading capacity > 45 kg Au/tC, abrasion resistance factor > 75/100)were reached. The loading capacity and abrasion resistance factor were unaffected by time, temperature and moisture content. Time, temperature and the interaction of time and moisture content had an effect on the activity. In general the wetter carbon performance best.
