Sažetak
Organic solid wastes are booming as society and industry rapidly develop, and it is necessary to reuse and recycle organic solid wastes to embrace a green and sustainable future. In this study, the mechanisms of microwave heating by comparing electrical heating were illustrated, the oil recovery performance during the microwave-assisted pyrolysis process of organic solid wastes was detailed, and the blueprint for sustainable high-quality aviation oil recovery from organic solid waste through using microwave assisted heating technology was drafted. Microwave heating technology has the advantages of less reaction time, more rapid product formation, and lower reaction activation energy compared with electrical heating technology. The oil yields of the biomasses are below 50 wt. %, much lower than plastics (99, 78, 40, 98, and 79 wt. %). The oil components of organic solid wastes are hydrocarbons and oxygenated derivatives hydrocarbons, and the carbon numbers are mainly from C7 to C16. The highest recovered energy efficiency is 97% with the highest total energy efficiency of 63% when the microwave power is 650 W and the pyrolysis temperature is 460 oC for the polystyrene by using SiC. The unitary cost and unitary energy economic cost of the sustainable high-quality aviation oil recovery from organic solid wastes were 3.2 × 104 CNY/t and 779 CNY/GJ, respectively. The microwave-assisted pyrolysis has a good production on the oil yield and quality, and embraces good economic benefits and industrialization prospects. The aviation oil recovery blueprint can be drafted as: the organic solid wastes are recycled by the treatment plant, decomposed in the microwave pyrolysis factory, processed with some additives in the aviation fuel factory, and finally used in airplanes and filling stations.
