Title:
無灰炭の製造方法
Document Type and Number:
Japanese Patent JP4708463
Kind Code:
B2
Abstract:
A method for manufacturing hyper-coal is characterized by comprising a first slurry heating step (S1) for heat-treating slurry prepared by mixing coal and an aromatic solvent, a first separation step (S2) for separating the heat-treated slurry into a liquid component and a solid component, a second slurry heating step (S3) for heat-treating slurry prepared by adding and mixing a hydrogen donor solvent into the solid component at a temperature higher than or equal to the temperature of the heat treatment in the first slurry heating step (S1), a second separation step (S4) for separating the heat-treated slurry into a liquid component and a solid component, and an upgraded coal acquisition step (S5) for acquiring hyper-coal by removing the solvent from the liquid component, and further acquiring hyper-coal by removing the solvent from the liquid component separated in the first separation step.
