Ammonia (NH3 ) as an important chemical raw material has a direct influence on the development of agriculture, national economy and people's livelihood. It is a high temperature, high pressure, high energy consumption and heavy pollution process in the industrial synthesis of ammonia. Low-temperature plasma technology is a sustainable and promising technology for ammonia synthesis, which has become a research hotspot at home and abroad. In this work, nitrogen and hydrogen are used as raw materials, and nanosecond pulsed dielectric barrier discharge is used to synthesize ammonia at low temperature and atmospheric pressure. The effects of factors such as pulse peak voltage, pulse repetition frequency, total gas flow rate, and N2 ∶H2 volume ratio on the synthesis rate and energy yield of ammonia synthesis are investigated systematically through a single-factor experiment. Furthermore, through the orthogonal experimental evaluation, it is determined that the order of factors affecting the synthesis rate is: pulse peak voltage>pulse repetition frequency>gas volume ratio>gas total flow rate. The order of factors affecting the energy yield is: pulse peak voltage>gas volume ratio>pulse repetition frequency>total gas flow rate. Combined with these two parts of experiments, the optimal conditions for ammonia synthesis are finally obtained: Pulse peak voltage 16 kV, pulse repetition frequency 6 kHz, pulse rising edge 100 ns, V (N2 ) ∶V (H2 ) =1∶1, and total gas flow rate 200 mL/min. Under this condition, the highest NH3 synthesis rate is up to 923. 08 μmol/h and the energy yield is 0. 30 g/kWh, respectively. [ABSTRACT FROM AUTHOR]

Slag-metal equilibrium experiments and a thermodynamic model of the action concentration based on the ion and molecule coexistence theory (IMCT) were used to study in controlling Al and Ti elements during the electroslag remelting (ESR) process of Inconel 625 alloy. The influencing mechanisms of slag components on burning loss of Al and Ti were investigated and the relationship of the activity and its ratio for each slag component with chemical composition in the system was provided, respectively. The results indicate that the slag system with the TiO2 of 3% has a good effect on the Al and Ti preservation. The CaO in the slag will cause different degrees of burning loss of Al and Ti, in which the excess CaO can lead to the phenomenon of burning the Ti and increasing the Al content. The Al oxidation is restrained with the temperature, in contrast to the Ti oxidation. Eventually, at the 1823K, the composition of the slag system is selected as w(CaF2)=50%~60%, w(Al2O3)=15%~20%, w(CaO)=14%~20%, w(MgO)=3% and w(TiO2)=2.5%~3.5%, respectively, so as to reduce the Al and Ti burnout effectively during the ESR process of Inconel 625.
