Abstract

213,252. Perten, J. March 19, 1923, [Convention date]. Carbon.-A decolourizing carbon, particularly suitable for decolorizing red wines. is prepared by carbonizing organic substances, such as wood waste, charcoal, peat, cellulose, grains, (brewers' grains, distillers' grains), animal waste, and spent charcoal, which have been previously impregnated with a strong solution of zinc chloride and a substantially equal volume of a strong solution of calcium chloride, the latter being wholly or partly replaced, if desired, 'by equivalent amounts of the chlorides of the alkali, alkaline earth, or earth metals, such as potassium, strontium, magnesium, or manganese. In an example, peat, sawdust, &c. is impregnated with equal volumes of strong solutions of zinc and potassium chlorides, dried, and carbonized. The product is washed with water, acid, and again with water, and then dried and ground. Specification 10126/14 is referred to.
