English

Subject field(s)
  • Anti-pollution Measures
  • Motor Vehicles and Bicycles
CONT

The oxidation or two-way catalytic converter reduces hydrocarbons (HC) and carbon monoxide (CO) by converting them into water vapor (H2O) and carbon dioxide (CO2). The nitrogen oxide (NOx) remains untouched and is emitted as exhaust.

OBS

The dual-bed or three-way catalyst, consisting of two chambers, reduces hydrocarbons (HC), carbon monoxide (CO) and nitrogen oxides (NOx) by converting them to water vapour (H2O), carbon dioxide (CO2) and nitrogen (N2).

Key term(s)
  • oxydation catalytic converter
  • oxydation catalyst
  • oxidation catalyst system

French

Domaine(s)
  • Mesures antipollution

OBS

Dispositif qui traite les imbrûlés(HC) et le monoxyde de carbone(CO) au moyen de pastilles recouvertes d’un métal noble(platine, palladium, rhodium) agissant comme catalyseur pour produire des produits inoffensifs(vapeur d’eau de gaz carbonique).

Record 2 2004-04-30

English

Subject field(s)
  • Analytical Chemistry
DEF

Any of the six gases comprising the extreme right-hand group of the Periodic Table, namely, helium, neon, argon, krypton, xenon, and radon.

OBS

[Rare gases] are preferably called noble gases or (less accurately) inert gases. The first three have a valence of 0 and are truly inert, but the others can form compounds to a limited extent.

OBS

noble: In chemical terminology this term describes an element which either is completely unreactive or reacts only to a limited extent with other elements. Six noble gases constitute a group in the Periodic Table that is variously called the zero group (as the first three of its members have a valence of zero), the inert gas group, and the noble gas group. The last is preferable, as three of the gases, through unreactive, are not inert.

OBS

noble gas: term officially preferred by the International Union of Pure and Applied Chemistry.

French

Domaine(s)
  • Chimie analytique
DEF

Un des gaz (hélium, néon, argon, krypton, xénon, radon) dont l’ensemble constitue la colonne 0 de la classification périodique des éléments.

OBS

Jusqu’en 1962, les gaz rares étaient appelés «gaz inertes», car ils étaient considérés comme chimiquement inertes.

OBS

Dans la mesure où les gaz dits inertes ne sont que relativement inactifs, on les désigne aussi sous le nom de gaz nobles par analogie avec les métaux nobles. [Par exemple :] L’azote, gaz inerte.
