Abstract

Hydrogen generation from water, methane, and methanol was investigated with different types of nonthermal plasma reactors under different conditions. With a ferroelectric packed-bed reactor in N2, hydrogen gas yield decreased in the order: methanol > methane > water. A similar trend was observed with a silent discharge plasma reactor, but substrate conversions were much lower with the latter reactor. At fixed specific energy densities, higher H2 yields were obtained at higher gas flow rates in the reactions of the above substrates. The initial water concentration was optimized at ca. 2.0% to obtain the largest H2 amount. Background O2 suppressed H2 yield. The ferroelectric packed-bed reactor could be operated continuously for 10 h without any decrease in H2 yield.
