Summary:•A cost-effective thermal extraction was at an applicable temperature and pressure.•It is workable and effective for industry application with creosote oil.•Extracted from slight-caking coals instead of the more expensive high-caking coals.•Thermoplasticity and strength of coals were improved by addition of coal extracts. Thermoplasticity and coke strength of individual coals and coal blends were improved by addition of coal extracts. Thus, this process caused the coals to bind better. Additionally, the strength of coke increased after the addition of 0–10 wt% of extracts from various caking coals. This result fully demonstrates that the extracts are a useful binder for coals.
