The Effect of Oxygen-Functional Groups on the Water Resistance of Lignite Briquette

Abstract:

Because of the increased demand for coal resources, the use of low-quality lignite increased. Heating-Pressing Utilizing is a better method to process fine lignite particles. The water resistance of lignite briquettes is important. In this study, the Baorixile lignite was dried in a lab-scale tube reactor and on pilot line. The oxygenic functional groups of lignite were analyzed at different temperature. The result indicated that carboxyl groups and phenols decreased as the temperature increasing, and phenols plays a more important role on the waterproof of lignite briquettes, especially at high temperature.
