Document Type and Number:

WIPO Patent Application WO/2010/044376

Kind Code:

A1

Abstract:

Provided is a manufacturing method for a solid molded fuel that can reduce the molding cost while maintaining the strength of the molded product. A mixed oil that includes a heavy oil and a solvent oil, and a porous coal are mixed to obtain a slurry. The slurry is dehydrated by heating to obtain a dehydrated slurry. Solvent oil is separated from the dehydrated slurry to obtain a cake, the cake is heated, and solvent oil is additionally separated from the cake to obtain a modified coal.
