Delessert successfully demonstrated the use of charcoal for decolorizing sugar-beet liquor.

He was directly responsible for the growth of the sugar beet industry in France.

Many of their disclosures are relevant to processes now in industrial use.

They were not developed on a commercial scale because of engineering difficulties.

Von Ostrejko set the basis for the commercial development of activated carbons through processes involving (a) the incorporation of metallic chlorides with carbonaceous material before carbonization and (b) the mild oxidation of charred materials with carbon dioxide or steam at raised temperatures.

Marketing of first industrially produced activated carbon, 'Eponit" (trade name), by the Fanto Works, Austria.

Schatten systematized the use of a hydrochloric acid wash prior to heating in the regeneration of bones chars.

This effectively removed the minerals salts adsorbed on to the carbon.

It was marketed as a decolorizer for the sugar-refining industry. Wood chars (charcoal) used for the reduction of copper, zinc and tin ores in the manufacture of bronze. The first recorded application of charcoal for medicinal purposes was cited in Egyptian papyri.The principle use appears to have been the application of charcoal to adsorb odorous vapours from putrefying wounds and from within the intestinal tract.At this time, too, the developing sugar refining industry was looking for an effective means of decolorizing raw sugar syrups.However, the wood charcoals available at this time were not particularly effective in this role, presumably because their porosity had not been developed beyond the extent produced by carbonization.
