Design and application on controllable output energy per unit mass of microwave pyrolysis apparatus

Microwave technology has gained tremendous importance in the thermo-chemical treatment of waste materials, including biomass, waste cooking oil, used engine oil, scrap tires, algae and others. The key to the improvement of utilization efficiency is the design of the microwave pyrolysis reactor. The controllable output energy per unit mass of microwave pyrolysis apparatus is designed on the basis of previous studies. To ensure the absorbed energy unchanged in the pyrolysis reaction process, the microwave power is decreased with the reduction of sample weight and reaction time. Compared with the traditional pyrolysis, the coking reaction is effectively inhibited under the irradiation of high power microwave, which ensures the pyrolysis of the samples undertaken under the stable conditions. The structural design and technical program for pyrolysis reactor is highlighted in this study. The related experiments are performed as well.
