Conversion of poisonous methanethiol to hydrogen-rich gas by chemisorption/reforming over nano-scale CeO2: The use of CeO2 as catalyst coating material

▶ Steam reforming of CH3SH over CeO2 generates H2-rich gas (H2, CO and CO2). ▶ With sufficient inlet steam content, CeO2 phase turns to Ce(SO4)2 during reaction. ▶ Ce(SO4)2 has high OSC, high lattice oxygen mobility and good reforming activity. ▶ Without (or with low steam content), CeO2 phase turns to Ce2O2S during reaction. ▶ Ce2O2S has low OSC, low lattice oxygen mobility and poor reforming activity.
