Formed samples containing biomass (cedar wood powder) were heated first to 450-600°C at 10-40°C/min under pressure in an inert atmosphere and then to 800°C at 3°C/min under ambient pressure. The principal conclusions were summarized as follows: (1) Rapid heating treatment in the softening and melting temperature range of coal was effective in improving coke strength even in the presence of biomass. (2) Formed samples containing 3-5 % biomass without any pretreatment could produce coke of 4-5 MPa, though the coke strength was lower than that of standard blended coal. (3) It was found that biomass modified in 1-methylnaphthalene could maintain the coke strength at the standard blended coal level (approximately 9 MPa).
