With the rapid development of global economy, climate change and energy scarcity have been the fact that there is no conflict. International society has increasingly reached consensus, and development of low-carbon economy and new energy has become the main means to solve this problem in order to solve energy and climate problems. Ammonia is a zero carbon compound and has a high energy density. The ammonia can be completely produced by renewable energy sources such as water, electricity, air and the like, and is low-carbon, pollution-free and environment-friendly energy, and in addition, the ammonia is relatively low in price and high in safety and is a hydrogen energy carrier. Therefore, ammonia has also received great attention from the energy industry, based on its above characteristics, and under the background that the environmental demand continues to rise.
However, ammonia as a fuel contains many problems to be solved. When ammonia is completely combusted in oxygen, only nitrogen and water are discharged, but in practical work, the complete combustion of ammonia is difficult to realize, the incomplete combustion of ammonia fuel in a combustion engine can cause exhaust emission containing a large amount of nitrogen oxides, and pure ammonia fuel has a low calorific value and requires high ignition energy, which makes the pure ammonia combustion more difficult.
Compared with the traditional turbine taking air as a working medium, the turbine taking hydrogen as the working medium has larger work capacity under the conditions of the same total inlet temperature, total pressure and pressure drop ratio. The ammonia gas is used as a hydrogen energy carrier, the hydrogen storage mass fraction is as high as 17.6%, the volume hydrogen storage density is high, and the ammonia gas can be regenerated and stored conveniently, so that the ammonia gas is an ideal hydrogen storage medium. Therefore, the synthesis gas containing hydrogen obtained by ammonia decomposition can be used for driving a turbine to do work and generate electricity.
There are three main ways of ammonia decomposition: electrochemical, mechanochemical, and thermal or catalytic cracking processes. The purification method for hydrogen in ammonia decomposition synthesis gas comprises a pressure swing adsorption method, a membrane separation technology and a cryogenic adsorption method, wherein the pressure swing adsorption method is mature in technology, the hydrogen purity can reach 99.999%, the energy consumption is low, and the occupied area of a device and the device investment are low.
