Abstract
A method for accurately measuring the thermoplasticity of a coal whose thermoplasticity has been difficult to evaluate and determining whether the coal that is to be measured does not significantly reduce the coke strength when used for a coal blend is disclosed. Also disclosed is a method for evaluating a coal used as a raw material for coke and includes using a physical property value relating to a thermoplasticity of a coal as an index for evaluating the coal, wherein a primary or secondary amine including an aromatic ring have been added to the coal, thereby enhancing the thermoplasticity of the coal.
