Enrichment of residual carbon from coal gasification fine slag by spiral separator
Journal of Environmental Management, 2022Coal gasification is one of the most promising clean coal technologies. However, gasification process also produces a huge amount of solid waste of high carbon content, named coal gasification fine slag. The coal gasification fine slag is mainly handled by landfilling, which is not only a hazardous pollution, but also wasting the energy from residual ...

Changes of fungal diversity in fine coal gasification slag amendment pig manure composting
Bioresource Technology, 2021The purpose of this study was to investigate fungal diversity and relative abundance (RA) during pig manure composting via high-throughput sequencing approach. Fine coal gasification slag (FCGS) (0%, 2%, 4%, 6%, 8% and 10%) were added into composting raw materials as additive and performed 42 days. Adjust C/N and moisture to 30 and 65%.

The microwave absorption properties of residual carbon from coal gasification fine slag
Fuel, 2021Abstract The resource utilization of coal gasification fine slag (FS) is very urgent. The residual carbon (RC) from coal gasification FS was obtained via a facile two-step acid leaching process. The structure, compositions, micromorphology, thermal stability, and electromagnetic parameters of the RC were tested by variously analytical techniques in ...

Effect of Coal Gasification Fine Slag on the Physicochemical Properties of Soil
Water, Air, & Soil Pollution, 2019Coal gasification fine slag (CGFS), which is the by-product of entrained-flow coal gasification, has superior properties, such as a large surface area, a broad pore size distribution, and a high content of carbon. This material has the potential to amend poor soils.
