Fast microwave assisted pyrolysis of biomass using microwave absorbent

---

a b s t r a c t
A novel concept of fast microwave assisted pyrolysis (fMAP) in the presence of microwave absorbents
was presented and examined. Wood sawdust and corn stover were pyrolyzed by means of microwave
heating and silicon carbide (SiC) as microwave absorbent. The bio-oil was characterized, and the effects
of temperature, feedstock loading, particle sizes, and vacuum degree were analyzed. For wood sawdust, a
temperature of 480 0C, 50 grit SiC, with 2 g/min of biomass feeding, were the optimal conditions, with a
maximum bio-oil yield of 65 wt.%. For corn stover, temperatures ranging from 490 0C to 560 0C, biomass
particle sizes from 0.9 mm to 1.9 mm, and vacuum degree lower than 100 mmHg obtained a maximum
bio-oil yield of 64 wt.%. This study shows that the use of microwave absorbents for fMAP is feasible and a
promising technology to improve the practical values and commercial application outlook of microwave
based pyrolysis.
