These 2005 NASA computer model simulations—calculated based on data available at that time—illustrate how methane is destroyed as it rises. As air rises in the tropics, methane is carried upwards through the troposphere—the lowest portion of Earth's atmosphere which is 4 miles (6.4 km) to 12 miles (19 km) from the Earth's surface, into ...
Paul Sabatier (1854-1941) winner of the Nobel Prize in Chemistry in 1912 and discoverer of the reaction in 1897. The Sabatier reaction or Sabatier process produces methane and water from a reaction of hydrogen with carbon dioxide at elevated temperatures (optimally 300–400 °C) and pressures (perhaps 3 MPa [1]) in the presence of a nickel catalyst.
Performing the reaction in sulfuric acid at 220 °C means that the catalyst must be able to withstand these harsh conditions. A platinum-bipyrimidine complex serves as the catalyst. The mechanism for this system is similar to the one described above, where methane is first activated electrophilically to form a methyl-platinum intermediate.
Carbon dioxide emissions going into the air from burning fossil fuels and making cement hit an all time high last year of 36.8 billion metric tons, twice the amount spewed into the air 40 years ...
Great Dane, formerly known as Great Dane Trailers, is a Chicago, Illinois based manufacturer of truck dry van, refrigerated van and flatbed semi-trailers.Established in 1900 by J.P. Wheless and T.H. McMillan as the Savannah Blowpipe Company [1] in Savannah, Georgia, it has gone on to become one of the world's largest manufacturers of commercial truck trailers.
Methane (US: / ˈ m ɛ θ eɪ n / METH-ayn, UK: / ˈ m iː θ eɪ n / MEE-thayn) is a chemical compound with the chemical formula CH 4 (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas.
Increases in levels of carbon dioxide – the main greenhouse gas – from 2020 to 2021 was larger than the average annual growth rate over the last decade, with concentrations reaching 415.7 ...
The most common use of monopropellants [3] is in low-impulse monopropellant rocket motors, [4] such as reaction control thrusters, the usual propellant being hydrazine [5] [6] which is generally decomposed by exposure to an iridium [7] [8] catalyst bed (the hydrazine is pre-heated to keep the reactant liquid).
