RESEARCH PROGRESS OF PREPARATION OF CHARRING MATERIALS AND THEIR APPLICATION IN SOIL THERMAL CHARRING

The charring process and mechanism of traditional charring materials such as coke, activated carbon and biochar have been studied thoroughly. Charring reaction during soil thermal treatment process has an important influence on soil reuse. However, little attention has been paid on and its mechanism is unclear, so it is urgent to strengthen the related research. In order to refer to the achievements and experience of the traditional charring process, this paper discussed the preparation process and application of charring materials, the characterization methods of charring reaction process and the physicochemical properties of charring products, and the influencing factors of charring reaction process (charring methods, parameters, minerals and additives, etc.), as well as the guidance for the study on soil thermal treatment charring. Finally, several aspects were put forward during soil thermal treatment charring. The results showed that the charring characterization method could be used to analyse the charring behaviors of soil organic pollutants and identify the charring products. The yield and properties of charring products were related to many factors, and could be used to analyse the effects of soil thermal treatment conditions on charring behaviors.
