haber process
Học thuậtThân thiện
Definition
Noun: * An industrial chemical process: The Haber process is a specific, large-scale method for synthesizing ammonia (NH₃) from its constituent elements, nitrogen (N₂) and hydrogen (H₂). The reaction is conducted under conditions of high pressure and elevated temperature in the presence of a metal catalyst, typically iron.
Usage
The term "Haber process" is used as a proper noun to name this specific industrial procedure. It is always capitalized. * It functions as the subject or object of a sentence when discussing chemical engineering, industrial chemistry, or agricultural history. * It is often discussed in the context of fertilizer production, as ammonia is a primary feedstock for nitrogen-based fertilizers.
Examples
- The invention of the Haber process in the early 20th century revolutionized agriculture by enabling the mass production of fertilizers.
- Ammonia for industrial use is primarily manufactured via the Haber process.
- Understanding the Haber process is fundamental to the study of chemical equilibrium and catalytic reactions.
Advanced Usage
- The process is also referred to historically and in some technical contexts as the Haber–Bosch process, acknowledging the engineering contributions of Carl Bosch who scaled it for industrial use.
- The conditions typically cited for the Haber process are a pressure of around 200 atmospheres, a temperature of approximately 450°C, and an iron oxide catalyst.
Variants and Related Words
- Haber–Bosch process (n): A synonymous term for the Haber process, emphasizing the industrial engineering aspect.
- Ammonia synthesis (n): The general chemical reaction of producing ammonia; the Haber process is the dominant industrial method for this synthesis.
- Nitrogen fixation (n): The broader process of converting atmospheric nitrogen (N₂) into a more reactive, usable form. The Haber process is a major method of industrial nitrogen fixation.
Synonyms
- Ammonia synthesis process
- Synthetic ammonia production
Related Concepts (Not Phrasal Verbs or Idioms)
- Chemical equilibrium: The Haber process is a classic example of applying Le Chatelier's principle to optimize the yield of a reversible reaction.
- Heterogeneous catalysis: The process relies on a solid iron catalyst to speed up the reaction between gaseous reactants.
- Feedstock: The hydrogen and nitrogen gases used as raw materials for the process.
Noun
- an industrial process for producing ammonia from nitrogen and hydrogen by combining them under high pressure in the presence of an iron catalyst
