Title:
METHOD OF EVALUATING COAL AND METHOD OF MANUFACTURING COKE
Document Type and Number:
WIPO Patent Application WO/2016/136191
Kind Code:
A1
Abstract:
Provided is a method of reliably measuring softening and melting properties of coal (non- or slightly-caking coal particularly) for which evaluation of the softening and melting properties was difficult, and evaluating, when the measured coal is used in a coal blend, whether or not coke strength is significantly reduced. This method of evaluating coal is a method of evaluating coal that is used as coke feedstock, and evaluates coal using, as an index, a property value relating to softening and melting properties of the coal to which a primary or secondary amine compound having an aromatic ring has been added to improve the softening and melting properties.
