  2. Pyrolysis - Wikipedia

    en.wikipedia.org/wiki/Pyrolysis

    ] Pyrolysis gas has a high percentage of heavy tar fractions, which condense at relatively high temperatures, preventing its direct use in gas burners and internal combustion engines, unlike syngas. The process is used heavily in the chemical industry, for example, to produce ethylene, many forms of carbon, and other chemicals from petroleum ...

  3. Kværner process - Wikipedia

    en.wikipedia.org/wiki/Kværner_process

    The natural gas is efficiently and completely transformed into pure carbon and hydrogen and does not release carbon dioxide into the atmosphere. After separating the mixture, the carbon particles can be used for instance as activated carbon, graphite or industrial soot, special kinds of carbon such as carbon discs and carbon cones (see SEM image).

  4. Hydrogen production - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_production

    Manufacturing elemental hydrogen requires the consumption of a hydrogen carrier such as a fossil fuel or water. The former carrier consumes the fossil resource and in the steam methane reforming (SMR) process produces greenhouse gas carbon dioxide. However, in the newer methane pyrolysis process no greenhouse gas carbon dioxide is produced ...

  5. Carbonization - Wikipedia

    en.wikipedia.org/wiki/Carbonization

    The gas produced by carbonization has a high content of carbon monoxide which is poisonous when breathed. Therefore, when working around the kiln or pit during operation and when the kiln is opened for unloading, care must be taken that proper ventilation is provided to allow the carbon monoxide, which is also produced during unloading through ...

  6. Pyrolysis oil - Wikipedia

    en.wikipedia.org/wiki/Pyrolysis_oil

    Pyrolysis oil, sometimes also known as biocrude or bio-oil, is a synthetic fuel with few industrial application and under investigation as substitute for petroleum.It is obtained by heating dried biomass without oxygen in a reactor at a temperature of about 500 °C (900 °F) with subsequent cooling, separation from the aqueous phase and other processes.

  7. Biochar carbon removal - Wikipedia

    en.wikipedia.org/wiki/Biochar_carbon_removal

    Biochar carbon removal (also called pyrogenic carbon capture and storage) is a negative emissions technology.It involves the production of biochar through pyrolysis of residual biomass and the subsequent application of the biochar in soils or durable materials (e.g. cement, tar).

  8. Pyrolysis gasoline - Wikipedia

    en.wikipedia.org/wiki/Pyrolysis_gasoline

    Pyrolysis gasoline or pygas is a naphtha-range product with high aromatics content. [1] It is a by-product of high temperature naphtha cracking during ethylene and propylene production, a high octane number mixture that contains aromatics from the aromatization reactions, olefins , and paraffins ranging from C5s to C12s.

    Blue gas burns with a blue flame and does not produce light except when used with a Welsbach gas mantle. Lowe's Water Gas: Water gas with a secondary pyrolysis reactor to introduce hydrocarbon gasses for illuminating purposes. [9] [10] Carburetted gas: Any gas produced by a process similar to Lowe's in which hydrocarbons are added for ...
