1. Carbon ammonium fertilizer is widely used, with obvious advantages such as fast effect, low price, economy, and no soil compaction: ammonium nitrogen does not need to be converted and can be directly used by plants; when coal is used as raw material to produce carbon ammonium, it emits more than 350 m3 less carbon dioxide than nitrogen fertilizers such as urea, and is an environmentally friendly nitrogen fertilizer. In addition to agricultural production, in order to make the best use of resources and avoid environmental pollution caused by burning straw, the use of ammonium bicarbonate effectively improves the utilization rate of reducing sugar and nitrogen after straw conversion and enzymatic hydrolysis, which is of great significance to the recycling of resources. Carbon ammonium used as fertilizer is generally colorless fine crystals, with a water content of less than 5% and a nitrogen content of about 17%. It consists of three components of ammonia (NH3), carbon dioxide (CO2) and water vapor (H2O) or four elements of carbon, hydrogen, oxygen and nitrogen, all of which are necessary nutrients for plants. It is suitable for all kinds of soils, can provide ammonium nitrogen and carbon dioxide required for crop growth at the same time, can be used as base fertilizer, and can be used as topdressing, etc., and is welcomed by farmers. The annual usage accounts for about 1/4 of the total nitrogen fertilizer production, and it is the most widely used nitrogen fertilizer product in my country besides urea. The disadvantages of ammonium carbonate are that it is volatile and has a low nitrogen utilization rate. Therefore, in production, we should make the best use of its strengths and avoid its weaknesses, and use it reasonably;

2. It is used as an analytical reagent, and is also used for synthesizing ammonium salts and degreasing fabrics;

3. It can be completely decomposed after heating and can be used as a high-grade food fermentation agent. Ammonium bicarbonate replaces alum as a leavening agent, and it produces a large amount of gas when used together with sodium bicarbonate. It can be used as a raw material for leavening agents such as bread, biscuits, pancakes, and fried dough sticks, and is also used as a raw material for foaming powdered juice. It is also used for blanching green vegetables, bamboo shoots, etc., as well as medicines and reagents;

4. In the pharmaceutical industry, when ammonium bicarbonate is added to 10-hydroxycamptothecin (HPCT), the distribution ratio of HPCT droplets (particles) with LDPPS (porous powder) characteristics is 51.6%, which is much higher than the 7%-25% ratio in ordinary powder inhalers, improving the atomization and deposition of DPIS (dry powder inhaler), prolonging the retention time of drugs in the lungs, and improving the efficacy of HPCT for lung cancer.

5. Used as a buffer; aerator.

6. Ammonium bicarbonate is widely used in plastic and rubber industries, pottery making, chrome tanning and synthetic catalysts.

7. Ammonium bicarbonate is a relatively cheap precipitant, which is often used to purify rare earth carbonates from rare earth ores, and ammonium bicarbonate is used as a precipitant in industry to prepare rare earth oxides.

8. In terms of ecological governance, first of all, ammonium bicarbonate can be used as the draw liquid of membrane permeation technology. Compared with other types of draw liquid, it has the characteristics of high interception rate, low toxicity, low energy consumption, low pollution, and good performance. The pollutant interception rate after treatment is above 98%. It has high practical significance. Secondly, ammonium bicarbonate has the ability to enhance the activity of heavy metals. Using ammonium bicarbonate as a regulator can significantly improve the purification of polluted soil by plants without causing the destruction of soil structure, the decline of internal biological activity, and the loss of soil nutrients. Finally, ammonium bicarbonate can be decomposed into non-ionic ammonia, providing nitrogen for the growth of algae such as Gracilaria, promoting the photosynthesis of algae, and increasing production. Compared with other control agents, ammonium bicarbonate has the advantages of low price and reduced environmental pollution, and is suitable for the control of marine polluting organisms.

It can be seen that ammonium bicarbonate is widely used and has a good market prospect. The production of its technological innovation product, long-acting ammonium carbonate, also represents the development direction of its new process technology.
