  2. Carbonization - Wikipedia

    en.wikipedia.org/wiki/Carbonization

    The tars and smoke produced from carbonization, although not directly poisonous, may have long-term damaging effects on the respiratory system. Housing areas should, where possible, be located so that prevailing winds carry smoke from charcoal operations away from them and batteries of kilns should not be located in close proximity to housing ...

  3. Hydrothermal carbonization - Wikipedia

    en.wikipedia.org/wiki/Hydrothermal_carbonization

    Biomass is heated together with water to 180 °C (356 °F) in a pressure vessel, in particular vegetable material (in the following reaction equation, simplified as sugar with the formula C 6 H 12 O 6). The pressure rises to about 1 megapascal (150 psi). During the reaction, oxonium ions are also formed which reduce the pH to pH 5 and lower.

  4. Activated carbon - Wikipedia

    en.wikipedia.org/wiki/Activated_carbon

    Activated carbon. Activated carbon, also called activated charcoal, is a form of carbon commonly used to filter contaminants from water and air, among many other uses. It is processed (activated) to have small, low-volume pores that greatly increase the surface area [1] [2] available for adsorption or chemical reactions. [3]

    Charcoal Burner by Helene Schjerfbeck, 1882. Saint Alexander of Comana (died c. 251) is known as "the charcoal burner". He is said to have taken up the job of the charcoal burner to avoid worldly acclaim. [10] A. A. Milne's poem "The Charcoal Burner" appeared in Now We Are Six, a collection of verse. [11] It begins: The Charcoal Burner has ...

  7. Fluidized bed reactor - Wikipedia

    en.wikipedia.org/wiki/Fluidized_bed_reactor

    A fluidized bed reactor (FBR) is a type of reactor device that can be used to carry out a variety of multiphase chemical reactions. In this type of reactor, a fluid (gas or liquid) is passed through a solid granular material (usually a catalyst) at high enough speeds to suspend the solid and cause it to behave as though it were a fluid.

  8. Water conservation - Wikipedia

    Also available are modern shower heads that help reduce wasting water: Old shower heads are said to use 5-10 gallons per minute, while new fixtures available use 2.5 gallons per minute and offer equal water coverage. [23] Another method is to recycle the water of the shower directly, by means a semi-closed system which features a pump and filter.

  9. Charcoal - Wikipedia

    en.wikipedia.org/wiki/Charcoal

    Lump charcoal is a traditional charcoal made directly from hardwood material. It usually produces far less ash than briquettes. Japanese charcoal has had pyroligneous acid removed during the charcoal making; it therefore produces almost no smell or smoke when burned. The traditional charcoal of Japan is classified into three types:
