Abstract
Hard compact briquettes of a highly reactive carbon which are especially suitable for use in the manufacture of carbon disulphide, are made by forming coherent bodies from a mixture of a finely ground coal starting material and an amine, which, in the liquid state, can "digest" or break down the internal structure of the coal, and heating the bodies to a carbonizing temperature of from 470 DEG -600 DEG C. at a rate such as to produce hard briquettes which have undergone no substantial swelling. The amine by itself may be added to the starting material or it may be added in the form of an "amine digestion mixture" as described in Specification 737,261 [Group XII], or as an "extract solution" as described in Specification 649,279, whilst activating agents such as sodium carbonate or sulphur may also be added to the mixture. The coal starting material may consist of a single coal, a mixture of coals or a coal mixed with substances such as anthracite, coke, peat or wood meal, the agglutinating value of the material being adjusted, if necessary, to fall within the range 5 to 15 by the addition of the anthracite, &c., or by oxidation. Aliphatic amines or hydroxy-amines such as n-propylamine, ethylene diamine, diethylene triamine or monoethanolamine, araliphatic amines such as benzylamine or aromatic amines such as aniline may be used singly or in mixtures of two or more in the proportion of one part of amine to from 4 to 10 parts of coal depending on the carbon content thereof. In an example, a mixture of 90 parts of coal with a carbon content of 84.3 per cent and an agglutinating value of 10 and 10 parts of mono-ethanolamine was pressed into briquettes which were heated at 100 DEG C. per hour to 500 DEG C. and held at this temperature for two hours. Specification 623,764 is referred to.
