Study on Carbocoal as Microwave Absorber in Microwave Field

Article Preview

Abstract:

The present paper decribed the effects of carbocoal on temperature rising characteristic during coal pyrolysis at different temperature in microwave field. Different mixture rate of carbocoal with coal and different final temperature on coal pyrolysis tempereature rising characteristics were studied in the work. The results indicate: Coal is a poorly microwave absorbing material. Because carbocoal can be fast heated in microwave field, so it can be used as additive for coal pyrolysis. Carbocoal otained from different pyrolysis temperature have different heating rate, along with the increase of carbocoal pyrolysis temperature, carbocoal heating rate increases in microwave field. Using carbocoal as microwave absorbent for coal rapid pyrolysis in microwave field is feasible.
