A study on microwave-assisted fast co-pyrolysis of chlorella and tire in the N 2 and CO 2 atmospheres

Abstract The microwave-assisted fast co-pyrolysis of chlorella and tire with additive under N 2 and CO 2 atmospheres were investigated. The pyrolysis profiles, yields of three-phase, the chemical composition of liquid and the ultimate analyses of solid residues were gained. With the tire ratio increasing, all the characters had the changes. The finial temperature had a wave change. The yield of liquid decreased and the chemical composition obtained in liquid of oxygenates compounds decreased, while hydrocarbon compounds increased, among which aromatic hydrocarbons had the highest content. The yield of solid increased, the HHV had a wave change and the values of H/C decreased. Under CO 2 atmosphere, the final temperatures were lower with 70% and 100% chlorella ratios, the yield difference of liquid reached the minimal with 70% and 30% chlorella ratios. According to the quantity and quality of liquid and solid, and the former results, 50% percentage of tire was the suitable ratio.
