含水石炭の脱水方法
Document Type and Number:
Japanese Patent JP4396944
Kind Code:
B2
Abstract:
A method for dewatering water-containing coal which includes heating the water-containing coal at a temperature of 100 to 350°C under a pressure not less than a saturated steam pressure at the temperature for the heating, while applying a shearing force of 0.01 to 20 MPa to the coal, in a sealed vessel. The method is novel and allows the production of dewatered coal which is inhibited from reabsorbing water after dewatering and is also inhibited from absorbing oxygen after dewatering.
