Title : Evolution characteristics and mechanisms of carbon structure of low-rank coal and biomass during hydrothermal carbonization and Joule heating treatment
Abstract:
Hydrothermal carbonization is one of the most efficient techniques for pre-treatment of moisture-containing feedstock, such as biomass, lignite and sewage sludge etc. While rapid Joule Heating (RJH) technology has become an effective way for the preparation of carbon materials by the advantages of applicable to all types of carbon sources, high energy efficiency and short time consumption. In this presentation, combination treatment of hydrothermal carbonization and RJH of biomass and low-rank coal for preparation of defective porous carbon materials is investigated. The pore structural and carbon structural evolution of defective porous carbon materials was analysed, as well as the surface functional groups. Besides that, its applications for electrode materials in three-electrode system and symmetric system in supercapacitors are further studied. Furthermore, the prospects and challenges for the clean and efficient utilization of biomass, low-rank coal and other carbon-containing solid waste in the future will also be investigated.
