Pyrolysis of Solid Waste by Thermogravimetric Analysis

Abstract:

Article Preview

Thermogravimetric (TG) analysis was used to study and compare the pyrolysis of the solid residues of pulping black liquor, turmeric industry wastewater, and rice stalk. The results showed that the higher heating value of the solid residues of turmeric industry wastewater and pulping black liquor, rice stalk were 15165.54, 10226.36, 16849.73 kJ/kg respectively. The decompose process of solid residues of turmeric industry wastewater and rice stalk were all concentrated in the 200 °C to 400 °C, while the solid residues of the pulping black liquor was from 200 °C to 600 °C. The DTGmax of solid residues of turmeric industry water was 14.95%•min-1 at 353.1 °C when heating rate at 50 °C min-1, and that of rice stalk was 41.85 %•min-1 at 338.4 °C, the solid residues of pulping black liquor pyrolysis peak was 30.35 %•min-1 at 870.3 °C. The study offered pyrolysis characteristics statistics about solid residues of pulping black liquor and turmeric industry wastewater, rice stalk to obtained valuable information about these solid wastes for fuel that can be potentially generated by pyrolysis.
