What 19.100 includes

• The coke included in this subclass is the solid residue from the distillation (or carbonization or gasification) of lignite or peat in a closed vessel. It is obtained in coke ovens from various grades of bituminous coal. Semi-coke comes from the distillation of coal or lignite at low temperatures; it may be pulverized or agglomerated. Retort carbon (or retort graphite) is a hard, black, brittle carbon that produces a metallic sound when struck. It is a product of gasworks or coke ovens, deposited on the oven walls; therefore, it occurs in irregular pieces, with one face flat or slightly curved. This product is often incorrectly called artificial graphite. Coal gas is obtained by distilling coal outside of contact with air in gasworks or coke ovens. It is a complex mixture of hydrogen, methane, carbon monoxide, etc., used for heating or lighting. Tar is a complex mixture of aromatic and aliphatic compounds in varying proportions, generally derived from the distillation of coal, lignite, or peat. Among these products, we can distinguish between: tar obtained from the high-temperature distillation of coal and tar from the low-temperature distillation of coal, lignite, or peat. Oils and derivative products (waterproofing materials and road coatings) are extracted from it. Pitch is the residue from the high- or low-temperature distillation of coal tar. It is used in the manufacture of electrodes, as a waterproofing agent, and as reconstituted tar for roads. Coal tar coke is the final residue from the distillation of high- or low-temperature coal tar. It is used as a raw material for manufacturing electrodes or as fuel. Petroleum coke: a residue from the cracking or distillation of petroleum taken to its extreme. It can be calcined (used in the manufacture of electrodes) or uncalcined (fuel). Petroleum bitumen: a residue from the distillation of crude oil. It is used as a waterproofing agent and as a road surface.
• The operation of coke ovens primarily for the production of: - coal tar - pitch - retort coal - coke and semi-coke - coke oven gas, from coal and lignite - coal gas - raw lignite - other waste products
• Coke agglomeration.
• Coke ovens for the production of solid fuels.
• Asphalt production.

What 19.100 excludes

• The production of agglomerated lignite (subclass 05.200).
• The distillation of coal tar (subclass 20.119).
• The manufacture of asphalt articles and similar materials, such as coal tar pitch (subclass 23.990).
• The production of industrial gas and other gases (subclass 35.201).
• The manufacture of asphalt within the construction industry (group 43.2).
