Abstract

Experimental comparisons of coke qualities with and without pitch incorporation during biomass/coal co-carbonization were conducted. Meanwhile, effects of biomass and pitch on the thermoplastic properties of the biomass/coal blends and coke quality indexes, such as M10, M40, CRI, and CSR were also discussed. Results indicated that the thermoplastic properties of the biomass/coal blends were enhanced by incorporation of the pitch. Adding 1.0% pitch could obviously enhance the coke quality indexes, the maximum amount of PSD and ST addition can be increased to 9.0% and 6.0%, respectively. Meanwhile, it was also found that the addition of PSD has no significant influence on the coke quality indexes when the mass concentration of PSD is below 6%, whereas the coke quality indexes are degraded gradually as the mass concentration of PSD is above 6%. The addition of ST also has a negative influence on the coke quality indexes. Even the addition of 3% ST will reduce the maximum fluidity of blend coals.
