In the production of fuel briquettes, different additives are used in order to improve the technical parameters. In the present study, two types of lignocellulosic binders including nanocellulose and lignin have been used. Due to the different chemical structure and difference in calorific value of each of these two materials (lignin and nanocellulose) and the difference in their mechanism of action on improving the thermal properties of fuel briquettes, in order to evaluate the final product of thermal analysis using calorific value and TGA and DTA diagrams were used. The results show the positive effects of the use of cellulosic binders in improving the thermal behavior of biofuel briquettes. Thermal analysis showed that 9% nanocellulose and 9% lignin treatments with 19.85 MJ / Kg and 25.75 MJ / Kg had the highest calorific value compared to the control sample, respectively. The diagram obtained from thermal analysis (TGA) of the control sample and the samples treated with lignin and nanocellulose show that the treated samples have lower weight loss rate, higher burning rate and higher burning temperature.
