Production of the briquette samples
The briquettes were produced using a manual hydraulic briquetting machine with three cylindrical mould of 1.5kg. Briquettes of coal and corn cob of different compositions were produced with a specific amount of Ca(OH)2 added based on the mass of coal was used as the desulfurizing agent and a certain amount of calcium sulphate based on the entire mass of the mixture was used as the briquette binder. During the production, specific quantity of water was added to the mixture to attain homogenity. The pressure was maintained at 5MPa throughout the production time. After the production of these briquettes, they were sun dried for 6 days before analysis
