Effect of mineral extraction on the evolution of nitrogen ...

2021-8-1 · The pyrrole-N decreases as the extraction progresses, and it is absent in the H-coal. This indicates that the minerals in each extraction stage promote the transformation of the N-5 in char-N to pyrrole-N in the tar. The H 2 O-soluble minerals inhibit the transformation of pyrrole-N to HCN.

Effect of mineral extraction on the evolution of nitrogen ...

2021-4-11 · By contrast, NH 4 Ac-soluble minerals make the tar-N content of the W-coal 86.3% higher than that of the N-coal. The gas-N was increased by the extraction. The HCl-soluble minerals were the most important factor affecting the gas-N yield, which results in a large amount of char-N being converted into gas-N, while the NH 4 Ac-soluble minerals inhibit the process.
