Hydrogen production through oxidative steam reforming of acetic acid over Ni catalysts supported on Ceria-based materials

In this work, CeO2-based supports have been prepared with Ni as the active phase, and they were tested in the oxidative steam reforming of acetic acid. The in-fluence of the O2/AcOH molar ratio (0 - 0.3) has been evaluated over Ni/CeO2.

The results stated that by increasing oxygen content in the feeding mixture, acetic acid conversion increases, too with a decrease in coke deposition, and hydrogen yield. To have a proper balance between the acetic acid conversion and the hydrogen yield an O2/AcOH molar ratio of 0.075 was selected to study the catalytic performance of Ni catalysts over different supports: commercial CeO2, a novel mesostructured CeO2, and CeO2-SBA-15.
