Dewatering and upgrading low rank coal by a two-step hydrothermal treatment |
| 摘要 |
Low rank coal is dewatered and upgraded by heating a coal/water mixture at 150 DEG to 300 DEG C. at a pressure preventing water vaporization, mechanically separating the water, then heating the coal at 300 DEG to 400 DEG C. at a pressure allowing water vaporization.
