Analysis of combustion characteristics and chemical properties for biocoke fuel

Analyses of the characteristics and properties of biocoke fuel from several biomass wastes were carried out to determine the energy potential of the fuel. Biocoke production in this research uses heating and pressure methods simultaneously under constant conditions. Experimental results using thermogravimetric analysis show that biocoke empty-fruit-bunches (EFB) have a higher energy potential of 26.57 MJ/kg. Meanwhile, mangrove biocoke recorded the lowest ash content at 1.81% compared to EFB at 5.09%. The carbon content of mangrove biocoke is 58.02%, slightly higher than that of EFB, 56.70%, but EFB is higher than that of other biomass. Overall, the energy content recorded in biocoke increased significantly compared to raw biomass.
