Methods of Producing Water-Resistant Solid Fuels |
摘要 |
The invention provides a method by which high moisture low rank coal or other carbonaceous material may be transformed into a high-energy, water resistant product. The raw feed is comminuted then mechanically compacted by a roller press with rolls of a specified profile to mobilize the inherent moisture and collapse most of the interstitial pore space. The mobilized moisture is then removed by low-temperature drying and the material is sized and shaped to form a product that is resistant to re-absorption of water or other liquids. The present invention will promote the use of low rank coal for liquefaction and gasification.
