hydrogen and syngas production. Nagai et al. [23] studied the dry
reforming of methane over the Rh/Al2O3 catalyst at temperatures
of 773–973 K, and found that CO2 addition in the reactants
significantly facilitated H2 formation from CH4 reforming and
reduced the catalyst deactivation caused by carbon deposition on
the active sites. Zhang et al. [24] experimentally investigated the
dry reforming of methane on the coal char catalyst in a fixed bed
reactor; they pointed out that the H2/CO ratio in the product gas
was strongly influenced by the CO2/CH4 ratio in the feed gas.
Labrecque and Lavoie [25] explored the dry reforming of methane
on an iron bed activated with an electric current, and the effect of
water vapor addition on the reaction was taken into account. They
discovered that the electron flow had a dramatic effect on the
