Embodiment 1
[0047] See figure 1 , figure 1 It is a process flow diagram of the coal pyrolysis analysis method provided in Example 1.
[0048] This embodiment mainly includes the following steps, which are respectively:
[0049] (1) Heat 2.704kg of low-quality A coal in the retort, the particle size of A coal is less than 6mm, stir while heating, heat to 300°C, and the heating rate is 5°C / min (Celsius / minute),
[0050] Keep the temperature constant for 10 minutes, and the products generated at this time pass through the oil-water receiving bottle and the absorption bottle set in turn; take the sample to analyze the collected products in the oil-water receiving bottle, and analyze the gas passing through the absorption bottle;
[0051] (2) Continue heating, stir while heating, heat to 500°C, and the heating rate is 5°C / min (Celsius / minute),
[0052] Keep the temperature constant for 10 minutes, and the products generated at this time pass through the oil-water receiving bottle and the ab...
Embodiment 2
[0059] The difference between this embodiment and embodiment 1 is that the heating rate is 4° C. / min.
