Effect of forming temperature on properties of biocoke from palm oil residues

Biocoke is a solid fuel produced from bio-residues such as agricultural residues. Biocoke is expected to use as a replacement for coal coke to reduce CO2 and pollution gases emission. In this research, biocoke was developed from palm oil residue which is one of the main wastes from palm oil industry. The effects of forming temperature on properties of the biocoke such as bulk density, maximum compressive strength and calorific value were investigated. Biocoke from palm oil residue was produced at different forming temperatures (from 140 degrees C to 190 degrees C). The forming time was fixed at 20 min. The forming pressure was also fixed at 16 MPa. The bulk density and calorific value of biocoke from palm residue increase with the increase of forming temperature. However, maximum compressive strength of biocoke from palm residue decreases with the increase of forming temperature.
