A coal extract, produced by thermal extraction and solvent de-ashing in 2-ring aromatic solvent, has an excellent thermoplasticity even though the parent coal appears no thermoplasticity. We named it "HPC, High Performance Caking additive", and have been developing to utilize as an thermoplasticity accelerator to make strong coke for blast furnace. This study concerns with the effect of HPC addition to improve the thermoplasticity of coal blends. Significant improvement in the thermoplasticity of coal blend was observed by HPC addition especially with high blending ratio of slightly coking coal. Coal blends were also thermally extracted in 2-ring aromatic solvent to investigate the quantitative relation with the amount of the extract. The amount of extract, which could be regarded as the thermoplastic-component, was increased with increase in HPC addition, and became more than the arithmetic mean of each coal's extraction yield, therefore, something interaction might be occurred by HPC addition.
