Development of internal structure observation of solid biofuel using microscopic analysis

Japan is facing carbon dioxide by 2050 at the 21st Conference of the Parties to the United Nations Framework Convention on Climate Change (COP21) held in 2015, as countries around the world are facing a situation where there is no time to deal with global warming. The goal is to reduce carbon emissions by 80%. In our laboratory, by developing a bio-solid fuel with higher density and higher hardness than non-carbonization conversion technology, we have brought coal coke closer to the properties required in a melting furnace and demonstrated a significant reduction in carbon dioxide. In order to develop a BIC that matches the dissolution characteristics, we will develop a method for observing the microscopic internal structure using ATR-FTIR. In this study, we process bio-coke to capture the changes in molecular structure that occur during molding of bio-coke and observe the internal structure by using spectroscopy. We report the results of experiments aimed at capturing the effects of pulverization methods and molding temperatures and changes in the internal structure of biocoke using quadratic differential analysis and PCA.
