Ammonia is one of the most important and widely used petrochemical products and is the second synthetic substance with the chemical formula NH3, which is formed in nature from the decomposition of nitrogenous organic matter. The highest amount of ammonia consumption is in the production of fertilizers (urea, ammonium sulfate, ammonium phosphates)China has many ammonia synthesis and fertilizer plants with huge capacity as we are a great agricultural country. In decades, China built hundreds plants and supported the development of the industry as demands of local market was increasing rapidly. Cooperating with those plants make us gaining enough experiences in the process and replacing oversea catalysts.What’s more, the development of ammonia synthesis and fertilizer industries makes China has strong abilities to supply reliable process technology and catalysts now. In the ammonia and fertilizer production of the world, the choice of reliable catalysts can increase the efficiency and cost-effectiveness of the entire process.
