Coal Gasification
In industrial chemistry, coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (), carbon dioxide (), methane (), and water vapour ()—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 add ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gasoline
Gasoline ( North American English) or petrol ( Commonwealth English) is a petrochemical product characterized as a transparent, yellowish, and flammable liquid normally used as a fuel for spark-ignited internal combustion engines. When formulated as a fuel for engines, gasoline is chemically composed of organic compounds derived from the fractional distillation of petroleum and later chemically enhanced with gasoline additives. It is a high-volume profitable product produced in crude oil refineries. The ability of a particular gasoline blend to resist premature ignition (which causes knocking and reduces efficiency in reciprocating engines) is measured by its octane rating. Tetraethyl lead was once widely used to increase the octane rating but is not used in modern automotive gasoline due to the health hazard. Aviation, off-road motor vehicles, and racing car engines still use leaded gasolines. Other substances are frequently added to gasoline to improve chemical st ...

Chaos (cosmogony)
Chaos () is the cosmological void state preceding the creation of the universe (the cosmos) in early Greek cosmology. It can also refer to an early state of the cosmos constituted of nothing but undifferentiated and indistinguishable matter. 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. Pherecydes of Syros (fl. 6th century BC) interprets ''chaos'' as water, like something formless that can be differentiated. Greco-Roman tradition Hesiod and the pre-Socratics use the Greek term in the context of cosmogony. Hesiod's Chaos has been interpreted as either "the gaping void above the Earth created when Earth and Sky are separated from their primordial unity" or "the gaping space below the ...

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 5-year willow tree experiment, his introduction of the word "gas" (from the Greek word ''chaos'') into the vocabulary of science, and his ideas on spontaneous generation. 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.

Synthetic Fuels Corporation
The Synthetic Fuels Corporation (SFC or Synfuels Corporation) was a U.S. federal government-funded corporation established in 1980 by the Energy Security Act (ESA) to create a financial bridge for the development and construction of commercial synthetic fuel manufacturing plants, such as coal gasification, that would produce alternatives to imported fossil fuels. With a seven-member board of directors, the corporation received $20 billion in initial funding to be used in joint ventures with private firms, primarily oil and gas companies, to construct plants and help finance coal mines or transportation facilities.Anthony S. Campagna, ''Economic Policy in the Carter Administration'' (Greenwood Press, 1995), 143. It was one of six acts in the ESA legislation. SFC also researched and promoted the use of alcohol fuels, solar energy, and the production of fuel from urban waste. Over its 6-year existence, the SFC only spent approximately $960 million (barely five percent of its init ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methanation
Methanation is the conversion of carbon monoxide and carbon dioxide (COx) to methane (CH4) through hydrogenation. The methanation reactions of COx were first discovered by Sabatier and Senderens in 1902. CO''x'' methanation has many practical applications. It is a means of carbon oxide removal from process gases and is also being discussed as an alternative to PROX in fuel processors for mobile fuel cell applications. Methanation as a means of producing synthetic natural gas has been considered since the 1970s. More recently it has been considered as a way to store energy produced from solar or wind power using power-to-gas systems in conjunction with existing natural gas storage. Chemical reactions The following reactions describe the methanation of carbon monoxide and carbon dioxide respectively: :CO + 3H2 -> CH4 + H2O -206 kJ/mol :CO2 + 4H2 -> CH4 + 2 H2O -164 kJ/mol The methanation reactions are classified as exothermic and their energy of formations are listed.

Net-zero Emissions
Global net-zero emissions is reached when greenhouse gas emissions and removals due to human activities are in balance. It is often called simply net zero. ''Emissions'' can refer to all greenhouse gases or only carbon dioxide (). Reaching net zero is necessary to stop further global warming. It requires deep cuts in emissions, for example by shifting from fossil fuels to sustainable energy, improving energy efficiency and halting deforestation. A small remaining fraction of emissions can then be offset using carbon dioxide removal. People often use the terms ''net-zero emissions'', ''carbon neutrality,'' and ''climate neutrality'' with the same meaning. However, in some cases, these terms have different meanings. For example, some standards for ''carbon neutral certification'' allow a lot of carbon offsetting. But ''net zero standards'' require reducing emissions to more than 90% and then only offsetting the remaining 10% or less to fall in line with 1.5 °C targets. Organ ...

Methanol To Gasoline
Gas to liquids (GTL) is a refinery process to convert natural gas or other gaseous hydrocarbons into longer-chain hydrocarbons, such as gasoline or diesel fuel. Methane-rich gases are converted into liquid synthetic fuels. Two general strategies exist: (i) direct partial combustion of methane to methanol and (ii) Fischer–Tropsch-like processes that convert carbon monoxide and hydrogen into hydrocarbons. Strategy ii is followed by diverse methods to convert the hydrogen-carbon monoxide mixtures to liquids. Direct partial combustion has been demonstrated in nature but not replicated commercially. Technologies reliant on partial combustion have been commercialized mainly in regions where natural gas is inexpensive. The motivation for GTL is to produce liquid fuels, which are more readily transported than methane. Methane must be cooled below its critical temperature of −82.3 °C in order to be liquified under pressure. Because of the associated cryogenic apparatus, LNG t ...
