Modelisation de la
pyrolyse oxydante ou noxydante de bois ou de dechets vegetaux a partir de leurs composants.
Trains use materials that
pyrolyse and char when a flame touches the surface of the combustibles.
Pour des hydrocarbures en C4 venant de la
pyrolyse catalytique d'huiles lourdes, on a etudie les comportements de craquage sur le catalyseur CEP-1 et le sable de quartz dans un reacteur a lit fluidise confine.
* Thermo chemical processing (such as
pyrolyse or degassing).
Gases from heating (
pyrolyse or gasification) biomass or glycerol, for instance, become clean and chemically active, and this allows for the transformation of those materials into clean fuels.
The plant materials in the ceramic crucibles were placed in a muffle furnace to
pyrolyse under oxygen-limited conditions.
The combustion process runs at 1,000[degrees]C and the combustion front
pyrolyses the coal behind it.

Pyrolysis experiments proved that the coal alone, heated in a single stage at a standard rate (used for coke production and standard
pyrolyses (Roubicek and Buchtele, 2002) of 3 K [min.sup.-1] to the final temperature of 900 [degrees]C yielded pyrolysis gas with a content of 54% [H.sub.2] and 22% C[H.sub.4].
