Abstract: In this research, briquette and briquetted charcoal were made by use of epiear of Carya cathayensis, Camellia oleifera, Chestnut and sawdust of pine and China fir. The character of densification and molding, and the quality of briquetted charcoal made by different proportions of epiear and sawdust were studied. The result indicated that cellulose and lignin content were different between epiear and sawdust of pine and China fir. Because ash contents of epiear were high, the raw stuff of briquette which has good characteristics of densification and molding must be mixed by epiear and sawdust of pine and China fir at a regular ratio. This paper also tested briquetted charcoal made by different ratio of epiear and sawdust. The result showed that the optimal ratio of epiear and sawdust was 3:7. In this condition, the briquetted charcoal has flat shape and no cracks. The yield of carbonization was 33.85%-36.73%, and the fixed carbon and combustion values of briquetted charcoal were 79.80%-86.20% and 28.96-31.92 MJ/kg, respectively.

Key words: epiear, densification and molding, briquette, briquetted charcoal
