This study investigated the mechanism of increase in coke strength on addition of binder. Strength of coke produced using 100% Goonyella caking coal was 3.0 MPa. The strength decreased to 2.3 MPa when 25% of Goonyella caking coal was replaced with 25% Adaro coal. To increase the strength of the coke produced by 75%GON+25%AD, 3 % of GON was replaced with 3% of solvent extracted MOHPC binder. The strength of the coke produced by 72%GON+25%AD+3%MOHPC was 3.5 MPa which was higher than the 100% GON coke. This study investigated the increase in strength on addition of binder by observing the binder-coal surface interaction using SEM-EDS analysis and coke matrix connectivity index using newly developed image analysis method.
