Calcium chloride is an inorganic compound, a salt composed of chlorine and calcium, which is a typical ionic halide. The characters are white, hard fragments or particles. Little bitterness, tasteless. Calcium chloride has a prominent adsorption capacity and low desorption temperature for ammonia. It has a great application prospect in the adsorption and separation of synthetic ammonia. However, calcium chloride is not easy to form stable porous materials, and has little contact with gas ammonia, and it is easy to expand and agglomerate during adsorption and desorption, which makes it difficult to put into practice in this aspect. The contact area of calcium chloride and ammonia can be greatly increased by carrying calcium chloride on the high specific surface carrier. The related studies have shown that the composite adsorbents prepared with calcium chloride on molecular sieves have better adsorption properties and stability than single adsorbents.

Calcium chloride, a salt composed of chlorine and calcium, the chemical formula is CaCl2. It is a typical ionic halide and a white solid at room temperature. It is commonly used in the use of salt water, road thawing and desiccant for refrigeration equipment. Because it is easy to absorb moisture in the air so [5] deliquescence, anhydrous calcium chloride in the container must be sealed storage. Calcium chloride and its hydrates and solutions have important applications in food manufacturing, building materials, medicine and biology.
