Destruction of Caking Properties of Coal by Pretreatment in a Fluidized Bed

Treating fine coals at 400/sup 0/ to 425/sup 0/C with a fluidizing gas composed of either inert gas or steam containing at least 0.2% oxygen destroys the caking properties of the coal. The minimum time required to produce a completely nonagglomerating char is about 5 minutes. The chars made may be u...

Zusammenfassung:	Treating fine coals at 400/sup 0/ to 425/sup 0/C with a fluidizing gas composed of either inert gas or steam containing at least 0.2% oxygen destroys the caking properties of the coal. The minimum time required to produce a completely nonagglomerating char is about 5 minutes. The chars made may be used as a feed for a fluidized-bed gasification or a hydrogasification process.
