Coal Gasification
Coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), methane (CH4), and water vapour (H2O)—from coal and water, air and/or oxygen. Historically, coal was gasified to produce coal gas, also known as "town gas". Coal gas is combustible and was used for heating and municipal lighting, before the advent of large-scale extraction of natural gas from oil wells. In current practice, large-scale coal gasification installations are primarily for electricity generation (both in conventional thermal power stations and molten carbonate fuel cell power stations), or for production of chemical feedstocks. The hydrogen obtained from coal gasification can be used for various purposes such as making ammonia, powering a hydrogen economy, or upgrading fossil fuels. Alternatively, coal-derived syngas can be converted into transportation fuels such as gasoline and diesel through additional treatment, or ...

Syngas
Syngas, or synthesis gas, is a mixture of hydrogen and carbon monoxide, in various ratios. The gas often contains some carbon dioxide and methane. It is principly used for producing ammonia or methanol. Syngas is combustible and can be used as a fuel. Historically, it has been used as a replacement for gasoline, when gasoline supply has been limited; for example, wood gas was used to power cars in Europe during WWII (in Germany alone half a million cars were built or rebuilt to run on wood gas). Production Syngas is produced by steam reforming or partial oxidation of natural gas or liquid hydrocarbons, or coal gasification. Steam reforming of methane is an endothermic reaction requiring 206 kJ/mol of methane: : In principle, but rarely in practice, biomass and related hydrocarbon feedstocks could be used to generate biogas and biochar in waste-to-energy gasification facilities. The gas generated (mostly methane and carbon dioxide) is sometimes described as ''syngas'' but its co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methanol
Methanol (also called methyl alcohol and wood spirit, amongst other names) is an organic chemical and the simplest aliphatic alcohol, with the formula C H3 O H (a methyl group linked to a hydroxyl group, often abbreviated as MeOH). It is a light, volatile, colourless, flammable liquid with a distinctive alcoholic odour similar to that of ethanol (potable alcohol). A polar solvent, methanol acquired the name wood alcohol because it was once produced chiefly by the destructive distillation of wood. Today, methanol is mainly produced industrially by hydrogenation of carbon monoxide. Methanol consists of a methyl group linked to a polar hydroxyl group. With more than 20 million tons produced annually, it is used as a precursor to other commodity chemicals, including formaldehyde, acetic acid, methyl tert-butyl ether, methyl benzoate, anisole, peroxyacids, as well as a host of more specialised chemicals. Occurrence Small amounts of methanol are present in normal, healthy hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soho, Birmingham
Soho is an area that is in Central Birmingham and Smethwick, approximately 2 miles north west of Birmingham city centre on the A41. The name is an abbreviation of South House, denoting that it was located to the south of Handsworth. The section of the A41 separating Handsworth from Winson Green is known as Soho Road. Soho expanded dramatically during the 19th century with the construction of numerous houses and factories, and immigration from the Commonwealth was centred in these homes during the 1950s and 1960s. Most of the immigrants who settled in Soho were of Indian origin. Further housebuilding took place by the local council during the 1960s and 1970s. Soho falls partly in the Soho ward of the City of Birmingham and partly in the Soho and Victoria ward of the Borough of Sandwell. Soho ward, Birmingham Until 1911 the part now within Birmingham formed part of Handsworth District, and is now a ward within the council constituency of Ladywood. Demography The 2001 Popul ...

William Murdoch
William Murdoch (sometimes spelled Murdock) (21 August 1754 – 15 November 1839) was a Scottish engineer and inventor. Murdoch was employed by the firm of Boulton & Watt and worked for them in Cornwall, as a steam engine erector for ten years, spending most of the rest of his life in Birmingham, England. Murdoch was the inventor of the oscillating cylinder steam engine, and gas lighting is attributed to him in the early 1790s, as well as the term "gasometer". However the Dutch-Belgian Academic Jean-Pierre Minckelers had already published on coal gasification and gas lighting in 1784, and had used gas to light his auditorium at the University of Leuven from 1785. Archibald Cochrane, 9th Earl of Dundonald, had also used gas for lighting his family estate from 1789 onwards. Murdoch also made innovations to the steam engine, including the sun and planet gear and D slide valve. He invented the steam gun and the pneumatic tube message system, and worked on one of the first Brit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wigan
Wigan ( ) is a large town in Greater Manchester, England, on the River Douglas, Lancashire, River Douglas. The town is midway between the two cities of Manchester, to the south-east, and Liverpool, to the south-west. Bolton lies to the north-east and Warrington to the south.

Wigan was incorporated as a Borough status in the United Kingdom, borough in 1246, following the issue of a charter by Henry III of England, King Henry III of England. At the end of the Middle ...

Chaos (cosmogony)
Chaos ( grc, χάος, kháos) is the mythological void state preceding the creation of the universe (the cosmos) in Greek creation myths. In Christian theology, the same term is used to refer to the gap or the abyss created by the separation of heaven and earth. Etymology Greek ''kháos'' () means 'emptiness, vast void, chasm, abyss', related to the verbs ''kháskō'' () and ''khaínō'' () 'gape, be wide open', from Proto-Indo-European ', cognate to Old English ''geanian'', 'to gape', whence English ''yawn''. It may also mean space, the expanse of air, the nether abyss or infinite darkness.Lidell-Scott, ''A Greek–English Lexiconchaos/ref> Pherecydes of Syros (fl. 6th century BC) interprets ''chaos'' as water, like something formless that can be differentiated.

Jan Baptista Van Helmont
Jan Baptist van Helmont (; ; 12 January 1580 – 30 December 1644) was a chemist, physiologist, and physician from Brussels. He worked during the years just after Paracelsus and the rise of iatrochemistry, and is sometimes considered to be "the founder of pneumatic chemistry". Van Helmont is remembered today largely for his ideas on spontaneous generation, his 5-year willow tree experiment, and his introduction of the word "gas" (from the Greek word ''chaos'') into the vocabulary of science. His name is also found rendered as Jan-Baptiste van Helmont, Johannes Baptista van Helmont, Johann Baptista von Helmont, Joan Baptista van Helmont, and other minor variants switching between ''von'' and ''van''. Early life and education Jan Baptist van Helmont was the youngest of five children of Maria (van) Stassaert and Christiaen van Helmont, a public prosecutor and Brussels council member, who had married in the Sint-Goedele church in 1567.Van den Bulck, E.
