Calcium chloride is an inorganic compound, a salt and calcium chloride by consisting, for typical ionic halide. Characters as a white, hard fragments or particles. Bitter, tasteless. Calcium chloride, ammonia adsorption capacity and outstanding low temperature desorption, has great potential applications in separation of ammonia adsorption.

However, due to the calcium chloride is not easy to form a stable porous material, with the ammonia gas contact area is small, and the adsorption, desorption process is easy to swell, agglomerate, thus making it difficult to put into practical use in that regard. The calcium chloride supported on high surface area support, can greatly increase the contact area of the calcium chloride and ammonia gas. Existing studies show that the composite adsorbent calcium chloride supported on zeolite prepared by adsorption and better stability than single adsorbent.

Calcium chloride, a salt and calcium chloride by elements of the chemical formula CaCl2. It is a typical ionic halide, at room temperature as a white solid. It Common applications include refrigeration equipment used in salt water, melting ice roads and dehydrating agent. Because it is easy to absorb moisture in the air occurs deliquescence [5], it is dried over anhydrous calcium chloride must be stored in sealed containers. Calcium chloride solution and hydrates and has important applications in many aspects of food manufacturing, building materials, medicine and biology.
