Abstract
This study presents a numerical investigation of hydrogen production from methane using an Inductively Coupled Plasma (ICP) reactor, emphasizing the influence of the input power on plasma characteristics and methane conversion. A two dimensional fluid model was developed and solved using the finite element method, incorporating more than 300 plasma chemical reactions to capture detailed kinetics. Simulations were performed for power levels ranging from 100W to 700W. Results show that increasing the input power significantly enhances plasma temperature from approximately 4500K to 8200K and elevate electron density from 1.2 × 10¹⁶ m⁻³ to 8.9 × 10¹⁶ m⁻³. Consequently, methane conversion efficiency rises from 35% to about 90%, with hydrogen yield increasing by nearly 70%. These findings confirm that higher input power strengthens electron energy and collision frequency, thereby improving energy transfer and methane dissociation. The proposed modeling approach provides valuable insights for optimizing plasma assisted methane reforming and supports the development of high efficiency hydrogen production technologies.
