The objective of this study was to produce briquette from the mixture of pyrolysis products. Palm shell was pyrolyzed at a temperature of 400 degrees C for 2 h holding time and heating rate of 10 degrees C/min. The biochar and bio- oil ratio was prepared at 3: 1 weight percentages for briquette. The viscosity of bio- oil was improved to increase the bonding forces. The characterization of biochar, bio-oil, coal and briquette were analyzed and presented in this study. The density and compressive strength of briquette were, respectively, found to be 0.94 gcm(-3) and 3.20 Nmm(-2). The shatter and water resistance of briquette were established to be 97 and 96 wt. %, respectively. The high heating value (HHV) of briquette was 29.6 MJkg(-1) greater than that of Malaysian sub-bituminous coal 24.6 MJkg(-1). It implies that the briquette produced is stable, durable and qualitative. Therefore, it can be concluded that the briquette can substitute coal in some applications.
