Abstract
Reviews
the use of ceria–zirconia based catalysts in hydrogen production from simple
alkanes and oxygenated hydrocarbons for the processes of steam reforming (SR),
autothermal reforming (‘ATR’), catalytic partial oxidation (‘CPO’), and dry
reforming (‘DR’).
Researchers explored the effects of operating conditions like molar
steam to carbon ratio, oxygen to carbon ratio, and temperature on the
performance of hydrogen production from methane, acetic acid, ethanol, and
glycerol SR and ATR of these feedstocks over ceria–zirconia supports have been
widely investigated. The use of these supports in the CPO and DR processes has
been studied mainly for methane as compared to oxygenated hydrocarbons. Ce-rich
supports were reported to be effective in hydrogen production from SR and ATR
of ethanol and glycerol and in steam methane reforming (SMR) in the ‘low’
temperature range, whereas zirconium-rich supports exhibited higher catalytic
activity in the ‘high’ temperature range.
