Reference excerpt

High temperature lignite coke (BHT coke) is a carbon-rich fuel that is produced from lignite by exposure to heat in the absence of oxygen (pyrolysis).

History Because East German industry urgently needed coke after the Second World War and the anthracite coal traditionally used for its production was found for the most part in western Germany, the two process engineers Erich Rammler and Georg Bilkenroth began researching and developing a metallurgical high-temperature lignite coke in 1949. This could be used for iron production, non-ferrous metallurgy and carbide production. The two scientists of the Bergakademie Freiberg concentrated their research on the Lower Lusatian lignite and in 1952 were finally able to obtain a patent for Lignite high-temperature gasification. The coke was produced both as bulk material and in briquette form.

Production facilities From 1952, the high temperature lignite coke was produced in the large coking plant VEB Braunkohleveredelung Lauchhammer and later also in the coking plant at VEB Gaskombinat Schwarze Pumpe. By-products of lignite coking are tar, medium oil and light oil as well as high-quality natural gas.

50-year anniversary celebration On 14 June 2002, former employees and cooperation experts were invited to Lauchhammer on the occasion of the 50th anniversary of the First Coke Tapping, as reported by the "Zeitschrift der Lausitzer und Mitteldeutschen Bergbau-Verwaltungsgesellschaft mbH" in its magazine LBMV konkret 4/2002, p. 7.

Worked examples

Example 1 — a first encounter with High temperature lignite coke

Start with the simplest possible case. Write down what High temperature lignite coke claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to High temperature lignite coke before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about High temperature lignite coke ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of High temperature lignite coke

In research: High temperature lignite coke appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses High temperature lignite coke in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: High temperature lignite coke is common in secondary-school and first-year university syllabi. It links to neighbouring topics Coal, so understanding it makes those chapters shorter.
In everyday life: Look for High temperature lignite coke outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
