  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. 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).

  4. 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.

  5. 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).

  6. 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 ...

  7. Hydrothermal liquefaction - Wikipedia

    en.wikipedia.org/wiki/Hydrothermal_liquefaction

    The plant materials used to produce bio-oils use photosynthesis to grow, and as such consume carbon dioxide from the atmosphere. The burning of the biofuels produced releases carbon dioxide into the atmosphere, but is nearly completely offset by the carbon dioxide consumed from growing the plants, resulting in a release of only 15-18 g of CO 2 ...

    The products will then go through a water-gas shift reactor to form CO 2 and H 2. The CO 2 that is produced will then be captured, and the H 2, which is a clean source, will be used for combustion to generate energy. [30] The process of gasification combined with syngas production is called Integrated Gasification Combined Cycle (IGCC). An Air ...

  9. Reactive flash volatilization - Wikipedia

    en.wikipedia.org/wiki/Reactive_flash_volatilization

    The catalyst guides the breakdown toward the production of syngas rather than toward water vapor and carbon. The syngas passes through the porous disk and is collected downstream in the tube. No external heating is needed because the chemical reactions release enough heat to break up molecules of oil or sugar following in their wake.
