Adrien Chenot
Adrien C. B. Chenot (born on August 30, 1803; died November 27, 1855) was a French engineer best known for his inventions in metallurgy as well as his research on manufactured gases. He is notably the inventor of one of the first modern methods of direct reduction of iron ore, based on the use of coal reacting with the ore in retorts . He exhibited the first samples of pre-reduced iron ore at the Lisbon Universal Exhibition of 1849, and was awarded the "''Grandes Medailles d'Or''" (Gold Medal of Honour) at the Paris Universal Exposition of 1855. Early life Born in Bar-sur-Aube, he went to school in Nancy then in Paris. In 1820, he entered the Ecole des mines de Paris, and on leaving this school, he was attached to the General Secretariat of the Department of Bridges and Roads. He left this post some time after to operate mines in Auvergne. Career In 1826, Chenot was asked by Auguste de Marmont, Duke of Raguse, to carry out metallurgical studies at Châtillon-sur-Saône, where ...

Bar-sur-Aube
Bar-sur-Aube (, literally ''Bar on Aube'') is a commune and a sub-prefecture in the Aube department in the Grand Est region of France. Surrounded by hills and Champagne vineyards, the city is traversed by the river Aube, from which it derives its name. The inhabitants of the commune are known as ''Baralbins'' or ''Baralbines'' and ''Barsuraubois'' or ''Barsurauboises''. The commune has been awarded three flowers by the ''National Council of Towns and Villages in Bloom'' in the ''Competition of cities and villages in Bloom''. Geography Bar-sur-Aube is located some 30 km west by north-west of Chaumont and 25 km south-east of Brienne-le-Château. Access to the commune is by the D619 road from Ailleville in the north-west which passes through the centre of the commune and the town before continuing east to Lignol-le-Château. The D396 branches off the D619 south-east of the town and goes south to Juvancourt. The D4 goes south-west from the town to Couvignon. The D1 ...

Blast Furnace
A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. ''Blast'' refers to the combustion air being "forced" or supplied above atmospheric pressure. In a blast furnace, fuel (coke (fuel), coke), ores, and Flux (metallurgy), flux (limestone) are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with oxygen enrichment) is blown into the lower section of the furnace through a series of pipes called tuyeres, so that the #Process engineering and chemistry, chemical reactions take place throughout the furnace as the material falls downward. The end products are usually molten metal and slag phases tapped from the bottom, and waste gases (flue gas) exiting from the top of the furnace. The downward flow of the ore along with the flux in contact with an upflow of hot, carbon monoxide-rich combustion gases is a countercurrent exchange and chemical ...

Prussia
Prussia, , Old Prussian: ''Prūsa'' or ''Prūsija'' was a German state on the southeast coast of the Baltic Sea. It formed the German Empire under Prussian rule when it united the German states in 1871. It was ''de facto'' dissolved by an emergency decree transferring powers of the Prussian government to German Chancellor Franz von Papen in 1932 and ''de jure'' by an Allied decree in 1947. For centuries, the House of Hohenzollern ruled Prussia, expanding its size with the Prussian Army. Prussia, with its capital at Königsberg and then, when it became the Kingdom of Prussia in 1701, Berlin, decisively shaped the history of Germany. In 1871, Prussian Minister-President Otto von Bismarck united most German principalities into the German Empire under his leadership, although this was considered to be a " Lesser Germany" because Austria and Switzerland were not included. In November 1918, the monarchies were abolished and the nobility lost its political power durin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reducing Agent
In chemistry, a reducing agent (also known as a reductant, reducer, or electron donor) is a chemical species that "donates" an electron to an (called the , , , or ). Examples of substances that are commonly reducing agents include the Earth metals, formic acid, oxalic acid, and sulfite compounds. In their pre-reaction states, reducers have extra electrons (that is, they are by themselves reduced) and oxidizers lack electrons (that is, they are by themselves oxidized). This is commonly expressed in terms of their oxidation states. An agent's oxidation state describes its degree of loss of electrons, where the higher the oxidation state then the fewer electrons it has. So initially, prior to the reaction, a reducing agent is typically in one of its lower possible oxidation states; its oxidation state increases during the reaction while that of the oxidizer decreases. Thus in a redox reaction, the agent whose oxidation state increases, that "loses/ donates electrons", that "i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Monoxide
Carbon monoxide ( chemical formula CO) is a colorless, poisonous, odorless, tasteless, flammable gas that is slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond. It is the simplest molecule of the oxocarbon family. In coordination complexes the carbon monoxide ligand is called carbonyl. It is a key ingredient in many processes in industrial chemistry. The most common source of carbon monoxide is the partial combustion of carbon-containing compounds, when insufficient oxygen or heat is present to produce carbon dioxide. There are also numerous environmental and biological sources that generate and emit a significant amount of carbon monoxide. It is important in the production of many compounds, including drugs, fragrances, and fuels. Upon emission into the atmosphere, carbon monoxide affects several processes that contribute to climate change. Carbon monoxide has important biological roles across phylog ...

Firminy
Firminy (; oc, Frominiu) is a commune in the Loire department in central France. It lies on the river Ondaine, 13 km southwest of Saint-Étienne by rail. History The ancient name of the town was ''Firminiaco'' or ''Firminiacus'' (lit. "place of Firmin"). The name was first recorded in a 971 charter by the King of Burgundy. Firminy had historically important coalmines known since the 14th century and extensive manufactures of iron, steel, and aluminum goods, including railway material, machinery and cannon. Fancy woolen hosiery was also manufactured. Population Sights Two historic churches from the 12th and 16th centuries are located here.

North Staffordshire
The federation of Stoke-on-Trent was the 1910 amalgamation of the six Staffordshire Potteries towns of Burslem, Tunstall, Stoke-upon-Trent, Hanley, Fenton and Longton into the single county borough of Stoke-on-Trent. An anomaly in the history of English local government, this was the first union of its type and the only such event to take place until the 1960s. The 1910 federation was the culmination of a process of urban growth and municipal change that started in the early 19th century. Little interaction between the separate settlements occurred until the 18th century when the pottery industry began to expand rapidly. By the early 19th century, initial steps had been made to ensure greater co-operation between the Potteries towns over the issue of law and order. The county plan of 1888 made the first attempts to form the six towns into one county borough, following an act of Parliament that restructured the county system and created the administrative county of Staffordsh ...

Barakaldo
Barakaldo ( es, Baracaldo; eu, Barakaldo ) is a municipality located in the Biscay province in the Basque Country. Located on the Left Bank of the Estuary of Bilbao, the city is part of Greater Bilbao, has a population at 100,881. Barakaldo has an industrial river-port heritage and has undergone significant redevelopment with new commercial and residential areas replacing the once active industrial zones. History The 1911 Encyclopædia Britannica original entry on the town stated: Iron mining formed a large part of Barakaldo's industry, making it the endpoint of a mining railway. The steel industry, led by Altos Hornos de Vizcaya, had an important presence during the 20th century, until the industrial recession hit the region's economy in the 1980s. In recent decades, the industrial zones surrounding Barakaldo have become less prominent, which can be owed to the shuttering of large companies such as Babcock & Wilcox. Although several factories remain, areas that were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
