Methanol is made from methane (natural gas) in a series of three reactions: Steam reforming CH 4 + H 2 O → CO + 3 H 2 Δ r H = +206 kJ mol −1 Water shift reaction CO + H 2 O → CO 2 + H 2 Δ r H = -41 kJ mol −1 Synthesis 2 H 2 + CO → CH 3 OH Δ r H = -92 kJ mol −1. The methanol thus formed may be converted to gasoline by the Mobil ...
C + H 2 O → CO + H 2 [1] CO + H 2 O → CO 2 + H 2 [1] C + CO 2 → 2CO [1] Steam reforming of methane is an endothermic reaction requiring 206 kJ/mol of methane: CH 4 + H 2 O → CO + 3 H 2. In principle, but rarely in practice, biomass and related hydrocarbon feedstocks could be used to generate biogas and biochar in waste-to-energy ...
CH a O b + 1-b / δ MeO x → CO + a / 2 H 2 + 1-b / δ MeO x-δ. where Me is a metal. It is noted that the reaction in the reducer of the CLR and CLG processes differs from that in the chemical looping combustion (CLC) process in that, the feedstock in CLC process is fully oxidized to CO 2 and H 2 O. In another reactor ...
In industrial chemistry, coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), methane (CH 4), and water vapour (H 2 O)—from coal and water, air and/or oxygen. Historically, coal was gasified to produce coal gas, also known as "town gas".
Steam reforming or steam methane reforming (SMR) is a method for producing syngas (hydrogen and carbon monoxide) by reaction of hydrocarbons with water. Commonly natural gas is the feedstock. The main purpose of this technology is often hydrogen production , although syngas has multiple other uses such as production of ammonia or methanol .
Power-to-gas (often abbreviated P2G) is a technology that uses electric power to produce a gaseous fuel. [1]Most P2G systems use electrolysis to produce hydrogen.The hydrogen can be used directly, [2] or further steps (known as two-stage P2G systems) may convert the hydrogen into syngas, methane, [3] or LPG.

Semi-water gas: Producer gas. Blue water-gas: Air, water or producer gas produced from clean fuels such as coke, charcoal and anthracite which contain insufficient hydrocarbon impurities for use as illuminating gas. Blue gas burns with a blue flame and does not produce light except when used with a Welsbach gas mantle.
Substitute natural gas (SNG), or synthetic natural gas, is a fuel gas (predominantly methane, CH 4) that can be produced from fossil fuels such as lignite coal, oil shale, or from biofuels (when it is named bio-SNG) or using electricity with power-to-gas systems.
