Methanol could produce hydrogen over some kinds of catalysts.
The reactions take place via the formation of CO as an intermediate
product, which is subsequently converted to CO2 by water–
gas-shift reaction (WGS). The overall reaction is aqueous phase
reforming (APR). While the APR is always accompanied by methanation
or Fischer–Tropsch reactions, which can generate methane
and other alkanes which could reduce the selectivity of H2
