The US Coal Industry in the Nineteenth Century – EH
The coal industry was a major foundation for American industrialization in the nineteenth century. As a fuel source, coal provided a cheap and efficient source of power for steam engines, furnaces, and forges across the United States. As an economic pursuit, coal spurred technological innovations in mine technology, energy consumption, and ...

Petroleum and Coal
Water gas formed by the reaction of coal with oxygen and steam is a mixture of CO, CO 2, and H 2. The ratio of H 2 to CO can be increased by adding water to this mixture, to take advantage of a reaction known as the water-gas shift reaction. CO ( g) + H 2 O ( g) CO 2 ( g) + H 2 ( g) Ho = -41.2 kJ/mol rxn.

Iron in the Industrial Revolution
As the industrial revolution developed, so did the iron industry. A set of innovations, from different materials to new techniques, allowed iron production to expand greatly. In 1709, Darby became the first man to smelt iron with coke (which is made from heating coal). Although this was a key date, the impact was limited — as the iron was ...

Coal Carbonization
The oven walls are gas heated, and a normal coal charge is 15 to 30 tons. The coal charge is heated to about 1,000°C and converted to coke in about 18 hours. The volatile matter in the coal is driven off as gases and tars and collected to be used as byproduct chemicals. Petroleum coke is made from the residues left from refining.
