Main Article Content
In this research, biocoke (the solid fuel made from bio-residues) was successfully produced from used coffee ground. The effect of particle sizes of used coffee ground on properties of the produced biocoke such as bulk density, maximum compressive strength and calorific value. The particle size used as raw materials are in the ranges of 595-1,000 micron, 400-595 micron and smaller than 400 micron. It is found that the biocoke produced from the particle size in the range of 595-1,000 micron has the highest bulk density at 1.3 g/cm3, and highest maximum compressive strength at 58.54 MPa. However, the calorific values of the produced biocoke increase with the decreasing in particle size (smaller than 400 micron) has the highest calorific value at 5,175 kcal/kg.
