Abstract
Smokeless fuel nuts are made from lean flame-producing coal having when dried more than 33% volatiles, by mixing the coal in dust form of maximum size 1 mm. with 7% to 10% by weight pitch and 5% by weight water to obtain a paste, pressing the nuts out of the paste, and heating the nuts at a rate of 5 DEG to 10 DEG C./minute, the rate of heating depending on the behaviour of a sample in the Arnu dilatometric test. If the test produces a contraction only, the rate is about 10 DEG C./minute; if it produces contraction followed by dilation to the original size, the rate is about 5 DEG C./minute. The heating may be to 400 DEG C. (if oxidation is required) or 700 DEG C. if the treatment is non-oxidizing. Sulphur and anthracene oil may be added to the paste, e.g. in amounts of 0.1% and 0.5% to 2% by weight respectively.
