Abstract
The invention specifically discloses a preparation process for ammonia, which belongs to the technical field of synthetic materials. The preparation process comprises the following steps: 1, placing a copper-platinum nanowire or iron-copper-platinum nanowire used as a catalyst into a reaction apparatus; 2, controlling temperature of the reaction apparatus to be 40 to 120 DEG C and atmospheric pressure to be less than 3 to 10 Pa; and 3, adding nitrogen and hydrogen as reactants and allowing a reaction to last for 40 to 80 m. The preparation process for ammonia provided by the invention overcomes the problems of low efficiency and poor quality of conventional synthesis technology, meets demands of middle and small-sized enterprises for synthesis technology, can rapidly synthesize and process high-quality ammonia and enables production cost of the enterprises and consumption of raw materials and energy to be reduced.
Description
Technical field
The present invention relates to the synthetic materials technical field, be specifically related to a kind of preparation technology for ammonia.
Background technology
As everyone knows, ammonia (Ammonia, i.e. ammonia), molecular formula is NH3, is a kind of colourless gas, and the strong impulse smell is arranged, and is soluble in water, 700 times of volume ammonia of 1 volume water dissolvable under the normal temperature and pressure.Ammonia is not only the important component of all foods and fertilizer, also is the direct or indirect compositions of all medicines, be normally used for making chemical fertilizer, thereby ammonia synthesizing industry occupies extremely important status in Economic development.
The temperature in the synthesis phase and pressure are not reasonably adjusted control in the existing synthetic ammonia technology, cause combined coefficient low, of poor quality, can't reach standard-required, also increase the input of enterprise's production cost simultaneously, waste a large amount of starting material and the energy.
