Experimental investigation of thermal effect in coal pyrolysis process

The thermal effects of five coal types' pyrolysis processes at heating rates of 5, 10, 15, 20, and 30 °C/min in the temperature range of 30–1000 °C were systemically investigated by thermogravimetric - differential scanning calorimetry. The experimental results show that coal pyrolysis process can be roughly divided into four stages, namely the drying and dehydration stage S1, the degassing stage S2, the pyrolysis stage S3, and the...
