Coke and semi-coke of coal Coke differs from coal in that it burns almost without flame and retains its porosity and gas permeability after combustion. It is infusible, harder, contains less sulphur and more carbon. As opposed to coke which is produced by the high-temperature (1 000 to 1 200 °C) carbonisation of coal, without air supply, semi-coke is produced by the carbonisation of coal...

Coke and semi-coke of lignite Lignites are not suitable for the production of coke by high-temperature carbonisation. However, low-temperature carbonisation yields a semi-coke for use as a smokeless fuel which is porous, glossy, clean to handle and ignites and burns readily.

2. 2. References in heading 27.10 to "petroleum oils and oils obtained from bituminous minerals" include not only petroleum oils and oils obtained from bituminous minerals but also similar oils, as well as those consisting mainly of mixed unsaturated hydrocarbons, obtained by any process, provided that the weight of the non-aromatic constituents exceeds that of the aromatic constituents. However, the references do not include liquid synthetic polyolefins of which less than 60% by volume distils...

3. 3. For the purposes of heading 27.10, "waste oils" means waste containing mainly petroleum oils and oils obtained from bituminous minerals (as described in Note 2 to this Chapter), whether or not mixed with water. These include: • (a) Such oils no longer fit for use as primary products (for example, used lubricating oils, used hydraulic oils and used transformer oils); • (b) Sludge oils from the storage tanks of petroleum oils, mainly containing such oils and a high concentration of...
