Optimization Of Microwave Liquid-phase Plasma Hydrogen Production Eauipment

With the expansion of the energy gap,as well as the increasingly serious environmental problems.It is urgent to find a new kind of green and clean energy.Hydrogen energy is gradually coming into people’s sight.Because of the high calorific value of hydrogen energy combustion,it will not pollute the environment after combustion,and is considered to be the best alternative to traditional fossil fuels.Microwave liquid-phase plasma hydrogen production technology is a new hydrogen production technology.Because the liquid phase discharge used in the hydrogen production method produces plasma and has high mass transfer efficiency,the hydrogen production effect is good,the hydrogen production is large,and the energy consumption of hydrogen production is low.The energy consumption of the hydrogen production technology is low,and it belongs to the best index of plasma hydrogen production method at present.In this paper,the parameter optimization of microwave liquid-phase plasma hydrogen production equipment is studied.In this study,hydrogen production and gas production energy consumption were improved from two aspects,through the optimization of reactor structure and the optimization of space location.The main conclusions are as follows:1.Expansion of reactor diameter:Expansion of reactor diameter is not conducive to hydrogen production under low microwave power conditions,which is due to the slow process of microwave heating and unstable discharge due to the expansion of reactor diameter The enlargement of reactor tube diameter is beneficial to hydrogen production under high microwave power,which is due to the enlargement of tube diameter to help plasma unfold,thus having more reaction space.2.Improvement of electrode space position:The best discharge position in microwave liquid phase discharge hydrogen production was found,that is,the tip of the electrode was 4 mm higher than the zero point.With the increase of the electrode height,the plasma generated near the tip of the electrode can enter a larger reaction space,thus increasing the gas production.3.By optimizing the microwave liquid-phase plasma hydrogen production equipment,the hydrogen production capacity and energy efficiency of the equipment are increased by 40%and 31.7%.4.The variation of gas production is explained from three aspects:generation mechanism of microwave liquid-phase plasma,plasma deployment and microwave thermal effect.
