Abstract

When coal and crude oil are associated, the immersion of crude oil affects the microstructure changes in coal oxidation process. In this work, thermogravimetric and in situ infrared spectroscopy experiments were used to study the oxidation characteristics and active functional groups evolution of oil-immersed coal. Results showed that the crude oil in coal slows down the oxidation process of coal and considerably affects weight gain phase due to O absorption. Considering crude oil O consumption and O attack on the active group methylene, the change law of methylene (2923 cm−1) with temperature can be used to represent the evolution of Aliphatic Functional Groups when the oil content is less than 10%. The characteristic demarcation point of the evolution rule of the active groups of coal with different oil ratios is 270 °C. The aromatic C = C of raw coal and 25% oil content coal samples satisfied the quadratic curve change relationship.
