WHAT DOES HABER PROCESS MEAN IN ENGLISH?
The Haber process, also called the Haber–Bosch process, is the industrial implementation of the reaction of nitrogen gas and hydrogen gas. It is the main industrial procedure to produce ammonia: N2 + 3 H2 → 2 NH3 Nitrogen is a strong limiting mineral nutrient in plant growth. Carbon and oxygen are also critical, but are easily obtained by plants from soil and air. Even though air is 78% nitrogen, atmospheric nitrogen is nutritionally unavailable because nitrogen molecules are held together by strong triple bonds. Nitrogen must be 'fixed', i.e. converted into some bioavailable form, through natural or man-made processes. It was not until the early 20th century that Fritz Haber developed the first practical process to convert atmospheric nitrogen to ammonia, which is nutritionally available. Prior to the discovery of the Haber process, ammonia had been difficult to produce on an industrial scale. Nitrogen fixation was already being done on an industrial scale using the Birkeland–Eyde process, but this is very energy-inefficient.
Definition of Haber process in the English dictionary
The definition of Haber process in the dictionary is an industrial process for producing ammonia by reacting atmospheric nitrogen with hydrogen at about 200 atmospheres and 500°C in the presence of a catalyst, usually iron.
