Analysis of chemical compounds and energy value for biocoke fuel by FTIR and TGA

The main objective of this research is to analyze the functional groups and the amount of energy in biocoke at different temperatures. Biocoke production is carried out simultaneously using pressure and heating methods. The Fourier transform infrared measurement range is 400–4000 cm−1, room temperature 18oC–25 °C, and humidity <65%. The spectrum of biocoke at pyrolysis temperatures of 150 °C and 190 °C has a %transmittance that is similar and a lower percentage compared to the spectrum of biocoke temperatures of 160 °C, 170 °C and 180 °C. Biocoke fuel samples with a temperature of 190 °C produced a higher-heating-value of 23.03 MJ/kg and lower-heating-value of 17.01 MJ/kg.
