Plasma-assisted production of hydrogen from hydrocarbons

Abstract

This paper is dedicated to the discussion of possible plasma applications for hydrogen-rich gas production from hydrocarbons. Different types of plasma, both thermal and nonequilibrium ones, are under consideration. A special attention is devoted to experimental and theoretical results on hydrocarbon conversion in nonequilibrium plasma of pulse microwave discharge. A comparison of plasma methods and conventional catalytic technology is presented as well.

Production of Hydrogen-Rich Gas from Methane by Thermal Plasma Reform

“…The characteristics of the production of syngas including H 2 -rich gas were investigated with the fuel CH 4 . Under the reference condition, syngas composition was 45.4% H 2 , 6.9% CO, 1.5% CO 2 , and 1.1% C 2 H 2 .…”

“…Reforming Reactions As the expected reactions are very diverse when we carry out the plasma reforming reaction by inputting steam into CH 4 , in this research reforming characteristics were investigated by selecting eqs 1-8, 5,6 and similar decomposition mechanisms were described elsewhere. [7][8][9] Partial oxidation reforming reaction;…”

“…Gas/steam lines supplied CH 4 , air, and steam. Methane and air were supplied by precise flow calculation at each mass flow controller (MFC, Bronkhorst F201AC-FAC-22-V).…”

“…A Molecular Sieve 5A column was used for the analysis of hydrogen, nitrogen, and oxygen. A Molecular Sieve 13X column was used for the analysis of CO, and a Poropak Q column was used for the analysis of hydrocarbons (i.e., CH 4 4 flow rate (i.e., ϳ23.7-47.1). The optimum H 2 production was termed the reference condition, found to be an input airflow rate of 5.1 L/min and an input power of 6.4 kW.…”

“…Therefore, to overcome such limitations, a plasma reforming 4 method that uses electric discharge is receiving attention. The plasma reforming method uses electrical energy and is effective in transforming various fuels because there is no generation of additional pollution impurities.…”
