September 1st, Chinese Academy of Sciences, Dalian Institute of Chemical Physics, Chen Ping researcher, Dr. Guo Jianping made important progress in the study of catalytic synthesis of ammonia. They put forward a "double active center" catalyst design strategy, and developed a series of transition metal and lithium hydride composite catalyst system to achieve the low temperature catalytic synthesis of ammonia. Synthesis of ammonia synthesis can be applied to the production of enterprise? Gold and silver island small series brief analysis is as follows.

　　Synthetic ammonia is one of the most basic chemical raw materials and is the main source of fertilizer. Although in theory, the reaction of nitrogen and hydrogen can be carried out at room temperature and atmospheric pressure. However, the process of industrial ammonia synthesis must be realized under high temperature and high pressure (500 - 350 C, 200 - 50 ATM). China is the largest country in the production of synthetic ammonia, the annual output is close to 30% of the world's total ammonia production. It can be seen that the development of low temperature, low pressure, high efficiency of the catalyst for the synthesis of ammonia has important strategic significance.

　　First of all, from the production of the operating costs of the enterprise, the need for high temperature and high pressure ammonia, need to consume a large amount of energy, in addition to high temperature and high pressure device material and operation process and strict, a little careless, not up to the conditions of temperature and pressure, can produce qualified products. At the same time, the conditions of high temperature and high pressure to grasp properly, may cause the device to stop the accident, etc.. So if it can be achieved will make the energy consumption and the cost of the device has been reduced.

　　Secondly, the operation of production of ammonia synthesis catalyst of low temperature and low pressure, high energy, so the transfer rate of ammonia can be greatly improved, the consumption can further reduce the pressure for cost reduction effects.

　　However, low temperature synthesis also has a certain negative effect on the life of the catalyst, and how much is the price of the purchase price of the catalyst. Although the laboratory has proven successful, but to be used in normal production also need to be further explored. If the catalyst replacement frequency is higher and the cost of catalyst to buy high, for the production of excess capacity of ammonia enterprises can not be a lot of use.

　　From this point of view, whether the new research into the actual production, still need to wait and see. There are many uncertain factors, and further exploration is needed. If it can be used for production, will bring more profits to the enterprise.
