“…In comparison to conventional heating, microwave pyrolysis involves transfer of energy to the biomass through the interaction of the molecules within the biomass [10][11][12]. Heating of biomass occurs when the microwaves cause dipolar molecules to attempt to rotate in phase with the alternating field of the microwaves [7].…”

Abstract:Biomass was subjected to conventional and microwave pyrolysis, to determine the influence of each process on the yield and composition of the derived gas, oil and char products.The influence of pyrolysis temperature and heating rate for the conventional pyrolysis and the microwave power was investigated. Two major stages of gas release were observed during biomass pyrolysis, the first being CO/CO 2 and the second one CH 4 /H 2 . This two-stage gas release was much more obvious for the conventional pyrolysis. While similar yield of liquid was obtained for both cases of conventional and microwave pyrolysis (~46 wt.%), higher gas yield was produced for the conventional pyrolysis; it is suggested that microwave pyrolysis is much faster. When the heating rate was increased, the peak release of CO and CO 2 was moved to higher reaction temperature for both conventional (500 °C) and microwave pyrolysis (200 °C). The production of CH 4 and H 2 were very low at a conventional pyrolysis temperature of 310 °C and microwave pyrolysis temperature of 200 °C (600 and 900 W). However, at higher heating rate of microwave pyrolysis, clear release of CH 4 was observed. This work tentatively demonstrates possible connections and difference for biomass pyrolysis using two different heating resources (conventional and microwave heating).

“…Therefore, the maximum temperature can be higher with more heat, and then more rice straw can be volatilized (i.e., higher weight loss). In addition, with increasing microwave power level, the heating rate of biomass pyrolysis can be increased as well [43]. Table 2 also shows that, when the maximum temperature was 350e500 C (250 W microwave power level), the weight loss was approximately 75e81 wt.% which means the yield of biochar was 19e25 wt.%.…”

“…One feasible pretreatment method is the microwave copyrolysis of sewage sludge and another biomass feedstock. Rice straw is an abundant agricultural waste and can be appropriately pyrolyzed using microwave heating [44]. After the addition of rice straw, the pyrolysis of sewage sludge can be more severe, especially when 20 wt.% rice straw added.…”
