Record 2 2011-08-18

English

Subject field(s)
  • Chemistry
DEF

A technique in which the dynamic modulus and/or damping of a substance (and/or its reaction product(s) under oscillatory load is measured as function of temperature whilst the substance is subjected to a controlled temperature programme.

French

Domaine(s)
  • Chimie
DEF

Technique utilisée pour mesurer, en fonction de la température, le coefficient dynamique et/ou l'amortissement d'une substance (et/ou de son ou de ses produits de réaction) sous l'effet d'une charge oscillatoire. La substance est soumise à un programme de température contrôlé.

Record 3 2008-05-15

English

Subject field(s)
  • Biomass Energy
CONT

The thermochemical pathway will use intact (raw) biomass or just the non-carbohydrate portion to produce synthesis gas (analogous to natural gas for electricity and heating) and/or heavy oils (analogous to heating oil used for space heating), either of which then can be converted into a wide range of fuels and chemicals products.

French

Domaine(s)
  • Énergie de la biomasse
CONT

Les technologies de transformation empruntent deux voies différentes selon l'état physique de la matière végétale dont on dispose : l'une thermochimique adaptée aux matériaux secs tels que le bois et la paille, l'autre biologique convenant mieux aux produits humides. Exemples de voies thermochimiques : combustion, pyrolyse, gazéification, hydrocraquage.

OBS

L'expression «voie sèche» est parfois utilisée comme synonyme de «voie thermochimique» et «filière thermochimique». Cependant, le terme «sèche» fait plutôt référence à la biomasse sèche qui subit la transformation.

Record 4 2008-05-15

English

Subject field(s)
  • Biomass Energy
CONT

Thermochemical conversion denotes technologies that use elevated temperatures to convert the biomass materials by (a) direct combustion to produce heat; (b) pyrolysis to produce gas, pyrolytic liquids, chemicals and char; (c) gasification to produce low or intermediate joule value gas ... and (d) liquefaction to produce heavy fuel oil or, with upgrading, lighter boiling liquid products used as distillates, light fuel oil or gasoline ...

Key term(s)
  • thermo-chemical conversion

French

Domaine(s)
  • Énergie de la biomasse
DEF

Processus thermique et chimique par lesquels des substances riches en carbone sont transformées en produits chimiques intermédiaires pour produire de l'énergie, des carburants, des produits chimiques et des matériaux.

Record 5 2002-08-19

English

Subject field(s)
  • Surface Treatment of Metals
CONT

Thermochemical diffusion treatments introduce interstitial elements, such as carbon, nitrogen and boron, or combinations of carbon and nitrogen, into a ferrous metal surface at elevated temperatures. However, the processes are not confined to interstitial diffusion; metallic substitutional elements or metalloids are used in processes such as chromising, aluminising and siliconising.

French

Domaine(s)
  • Traitements de surface des métaux
CONT

Les procédés de traitement de surface se répartissent en 5 grandes classes de procédés : revêtements par voie humide ; revêtements par voie sèche ; traitements de conversion chimique ou électrolytique ; traitements de diffusion thermochimique ; traitements superficiels par transformation structurale (mécanique).

Record 6 2001-05-28

English

Subject field(s)
  • Waste Management
CONT

As of 1992, only the KPEG dechlorination process and the EcoLogic thermochemical process had been demonstrated effective for treating sediment.

Key term(s)
  • thermo-chemical process
  • thermochemical recycling process

French

Domaine(s)
  • Gestion des déchets
CONT

En date de 1992, il semble que seules les technologies de déchloration par le système KPEG et le procédé thermochimique EcoLogic avaient démontré leur efficacité dans le traitement des sédiments.
