  2. Water gas - Wikipedia

    en.wikipedia.org/wiki/Water_gas

    Water gas is a kind of fuel gas, a mixture of carbon monoxide and hydrogen. It is produced by "alternately hot blowing a fuel layer [coke] with air and gasifying it with steam". It is produced by "alternately hot blowing a fuel layer [coke] with air and gasifying it with steam".

  3. Heat of combustion - Wikipedia

    en.wikipedia.org/wiki/Heat_of_combustion

    The combustion of a stoichiometric mixture of fuel and oxidizer (e.g. two moles of hydrogen and one mole of oxygen) in a steel container at 25 °C (77 °F) is initiated by an ignition device and the reactions allowed to complete. When hydrogen and oxygen react during combustion, water vapor is produced.

  4. Combustion - Wikipedia

    en.wikipedia.org/wiki/Combustion

    The flames caused as a result of a fuel undergoing combustion (burning) Air pollution abatement equipment provides combustion control for industrial processes.. Combustion, or burning, [1] is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke.

  5. Oxyhydrogen - Wikipedia

    en.wikipedia.org/wiki/Oxyhydrogen

    ' bang-gas '), although some authors define knallgas to be a generic term for the mixture of fuel with the precise amount of oxygen required for complete combustion, thus 2:1 oxyhydrogen would be called "hydrogen-knallgas". [3] "Brown's gas" and HHO are terms for oxyhydrogen originating in pseudoscience, although x H 2 + y O 2 is preferred due ...

  6. Syngas - Wikipedia

    en.wikipedia.org/wiki/Syngas

    Pure oxygen can be substituted for air to avoid the dilution effect, producing gas of much higher calorific value. In order to produce more hydrogen from this mixture, more steam is added and the water gas shift reaction is carried out: CO + H 2 O → CO 2 + H 2. The hydrogen can be separated from the CO 2 by pressure swing adsorption (PSA ...

  7. Water–gas shift reaction - Wikipedia

    en.wikipedia.org/wiki/Watergas_shift_reaction

    This is sometimes called the reverse watergas shift reaction. [20] Water gas is defined as a fuel gas consisting mainly of carbon monoxide (CO) and hydrogen (H 2). The term 'shift' in watergas shift means changing the water gas composition (CO:H 2) ratio. The ratio can be increased by adding CO 2 or reduced by adding steam to the reactor.

  8. Steam reforming - Wikipedia

    en.wikipedia.org/wiki/Steam_reforming

    Illustrating inputs and outputs of steam reforming of natural gas, a process to produce hydrogen and CO 2 greenhouse gas that may be captured with CCS. 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.

  9. Hydrogen - Wikipedia

    en.wikipedia.org/wiki/Hydrogen

    Hydrogen is a chemical element; it has symbol H and atomic number 1. It is the lightest element and, at standard conditions, is a gas of diatomic molecules with the formula H 2, sometimes called dihydrogen, [11] hydrogen gas, molecular hydrogen, or simply hydrogen. It is colorless, odorless, [12] non-toxic, and highly combustible.
