liquefaction [2 records]

English

Subject field(s)
  • Energy Transformation
  • Thermodynamics
  • Chemical Engineering
  • Biomass Energy
DEF

Conversion of a solid to a liquid by heat, or a gas into a liquid by cold or pressure.

CONT

... liquefaction, was historically linked to hydrogenation and other high-pressure (10-30 MPa) thermal decomposition processes which employed reactive hydrogen or carbon monoxide carrier gases to produce a liquid fuel from organics at moderate temperatures (300-400°C). However, over the past decade, liquefaction has often been used in the literature to encompass any thermochemical conversion process which primarily yields a liquid tar/oil product (pyrolysis is therefore included with hydrogenation as being "liquefaction").

  • Transformación de la energía
  • Termodinámica
  • Ingenieria química
  • Energía de la biomasa
DEF

Paso de un sólido o un gas al estado líquido.

CONT

Para licuar el aire, primero hay que comprimirlo con una bomba y hacerlo pasar por un tanque de enfriamiento. [...] el aire se enfría a -194°C, en que se licúa, y puede guardarse. [...] El mejor método de separar los gases del aire es la licuación del mismo.

Record 2 1980-06-12

English

Subject field(s)
  • Soil Science
OBS

The sudden large decrease of the shearing resistance of a cohesionless soil. It is caused by a collapse of the structure by shock or other strain and is associated with a sudden, temporary increase of the interstitial water pressure. It involves a temporary transformation of the material into a fluid mass.

French

Domaine(s)
  • Science du sol
OBS

Baisse importante et soudaine de la résistance au cisaillement d'un sol sans cohésion. Cette baisse est due à un effondrement de la structure causé par un choc ou une autre force, et est associée à un accroissement subit et temporaire de la pression de l'eau interstitielle. Ce phénomène comporte une transformation temporaire de la matière en une masse fluide.
