Integrated hydrothermal carbonization and chemical looping gasification system for resource recovery from sewage sludge towards carbon neutrality and pollutants mitigation (HTC-CLG)

The circular economy and carbon neutrality require environmentally friendly processes to convert waste streams into valuable chemicals and fuels and to reduce greenhouse gas emissions. In this project, municipal sewage sludge is converted into recyclable high-quality nutrient products and pure synthetic fuel gas using a new catalytic thermochemical process. The goal is to develop an integrated thermochemical system whose operation is comprehensively optimized based on catalyst design, chemical reactions, process control, and integration. The system could be applied to treat different biomass waste streams with high moisture and nitrogen content. In addition, the process can offer new opportunities to exploit carbon resources. The project supports the development of a sustainable society, a carbon-neutral society and a resource-efficient economy.
