carbonization

[‚kär·bə·nə′zā·shən]
(chemistry)
The conversion of a carbon-containing substance to carbon or a carbon residue as the destructive distillation of coal by heat in the absence of air, yielding a solid residue with a higher percentage of carbon than the original coal; carried on for the production of coke and of fuel gas.
(geochemistry)
In the coalification process, the accumulation of residual carbon by changes in organic material and their decomposition products.
Deposition of a thin film of carbon by slow decay of organic matter underwater.
A process of converting a carbonaceous material to carbon by removal of other components.

Spectroscopic analysis of carbonization behavior of wood, cellulose and lignin.
PAN fiber cannot be carbonized to form carbon fiber directly and must be stabilized at lower than 300 [degrees] C under air first, and then carbonized to form carbon fiber, because the structure changes at the stabilization stage from a linear structure, which can be burned off at higher temperature, to an aromatic structure, which is not burned off at the carbonization stage.
In addition, the Bergman cyclopolymerization mechanism allows for a wide range of processable reactive oligomers and a controlled network of structures prior to carbonization [3].
These results indicate that the density of woodceramics after carbonizing increases with increasing resin impregnation percentage; the same trend appeared at carbonization temperatures of 1000[degrees] and 1200[degrees]C.
On the other hand, the carbonization by the accumulated Fe-OMT on the surface of the sample provides an important effect, which will be illustrated by the photographs of char residues after cone calorimeter (Fig.
The far-infrared ray emission value of the woodceramics manufactured using a carbonization process at 600[degrees]C and a board with a PF resin impregnation ratio of 70 percent was 0.
The end result is the production of ethanol from the fermentation of the algae, methanol from the anaerobic digestion of the algae, biodiesel from the extraction and transesterification of the algae, high-quality coal from hydrothermal carbonization of the algae residue, electricity by converting ethanol and methanol to electrical energy, coal from hydrothermal carbonization and animal feed from the remaining protein residue -- and all in a carbon dioxide neutral way.
The industry's best shot at achieving the carbon fiber price reduction necessary for high-volume applications like automotive is the employment of polyolefin-precursor carbon fiber, combined with combined with plasma oxidation and carbonization.
