摘要：In this study, it is aimed to produce pellets for use as solid biofuel from corn stem and cotton shoes. Some thermo-chemical characteristics such as higher and lower heating values, hydrogen and total Sulphur contents, the moisture content in dry air, the total moisture at original basis and the volatile matters of the produced biopellets were determined based on the international standards. The determined thermo-chemical properties of the produced biopellets are compared to the standards used in the European Union for biomass-produced pellets. The moisture content of the corn and cotton pellets in dry air were determined to be 4.17% and 5.63%, respectively the moisture content of the corn and cotton pellets in dry air were determined to be 4.17% and 5.63%, respectively. The volatile matter content of the corn and cotton pellet samples in dry basis were determined to be 75.58% and 74.52%, respectively. The total Sulphur contents of the corn and cotton pellets in dry basis were determined to be 0.16% and 0.14%, respectively. The gross calorific value and the net calorific value of pellets produced from cotton and corn wastes in all states are suitable to the EN 14918 standard. The gross calorific value of cotton pellets in dry basis (19.46 MJ/kg) was determined to be about 6.53% higher than that of corn pellets (18.19 MJ/kg). The the net calorific value of cotton pellets (18.29 MJ/kg) in dry basis was determined to be about 8.89% higher than that of corn pellets (17.03 MJ/kg).
