A Thermodynamic Analysis of the Process of Hydrogen Production by Natural Gas Decomposition in The Low-Temperature Thermal Plasma Reactor
Апстракт
Hydrogen produced via the thermal decomposition of natural gas, also known as ‘turquoise’ hydrogen, is the subject of this study. It is expected that ‘turquoise’ hydrogen will play a significant role in the coming energy transition, reducing emissions from fossil fuels in the short term until renewable energy sources are capable of producing enough energy or hydrogen transport becomes feasible on a large scale. The main advantage of the thermal decomposition of natural gas is the possibility of obtaining a high yield of hydrogen without the emission of carbon monoxide or carbon dioxide since the main products of the process are carbon in a solid state and hydrogen. The use of plasma in the process elevates the temperature of the process and increases methane decomposition without the use of catalysts. This paper presents an analysis of the process using a thermodynamic equilibrium model based on the minimum of the Gibbs function in the temperature range of 500-2000 K. As a result of th...e study, the equilibrium composition of the system in the observed temperature range is presented. Also, attention is given to undesirable components in the system such as carbon dioxide, hydrocyanic acid, and nitrogen compounds like ammonia and nitrogen monoxide. From the point of energy analysis, the useful energy of the system per kilogram of fuel and the efficiency of the process is presented. The results of the numerical analysis show that the efficiency of the process increases with increasing temperature and reaches its maximum at a temperature of 1200 K when an energy efficiency of about 50% is achieved.
