Recover Carbon from Coal Gasification Fine Slag as ...

Benefiting from the carbon‐rich feature, such cheap by‐product of coal gasification industry can be used as precursors to prepare porous carbons for energy conversion and storage. In this work, new porous carbons are prepared by treating carbon‐rich fine slag by directly acid etching and ammonia activation.

Effect of Coal Gasification Fine Slag on the ...

2021-2-1 · Coal 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. This study was carried out to investigate the use of CGFS as a soil amendment for alkaline sandy lands.

Utilization of coal slag from pressurized coal ...

1980-6-1 · Slag tapped from pressurized slagging gasifiers has unique properties not associated with similar slag formed under nonpressurized conditions. Upon heating to a temperature in the 800 to 900 °C range, this slag expands to as much as twenty times its initial volume, producing a glass foam that is relatively inert and could be used to produce commercially viable insulating products.
