The development of hydrogen plasma greatly expanded generated by
microwave system has resulted in high energy efficiency. The application has a
pioneer invention used at atmospheric pressure. In addition, microwave frequency
of 2.45 GHz can assist decompose Carbon Dioxide and produce hydrogen as the
main component of the fuel. Therefore, this frequency plays as important role as
source of energy even to break down the plasma.
This research deals with the Maxwell-Boltzmann Equation to calculate the
electron and ion densities of hydrogen species corresponding to their temperatures.
The geometrical reactor model is designed applying a finite element method to
determine the most probable high electric field intensity and to integrate the
charged hydrogen species densities as well. The hybrid mesh grid is set to divide
the size domain and to obtain the effect of space-time characteristics in the plasma.
The results of this study describe that the characteristics of hydrogen plasma
can be generated in the range of 10-13 - 10-4s, showing an increment of electron
density from 1012m-3 to 5.24 x 1019m-3, electron temperature 1.1 eV, and the electric
field of 1.18 x 104 V/m. The performance of hydrogen plasma is depicted from the
change in the value of Voltage Standing Wave Ratio due to the collision frequency,
and the reflection parameter (S11) which reaches its minimum value of -5.21 dB,
indicating that the plasma only reflects 31.5%. The increment of reaction rate is
maintained at a period of 10-6s (3.01 x 106 mol/m3s), which then becomes an
indication that the hydrogen plasma and the other particles have reached
equilibrium state.
