Regeneration of NiAl₂O₄ spinel type catalysts used in the reforming of raw bio-oil

The regenerability of Ni catalysts in reforming reactions is a key factor for process viability. Accordingly, this study addresses the regeneration of two spinel NiAl₂O₄ type catalysts by reaction-regeneration cycles in the oxidative steam reforming (OSR) of raw bio-oil. The spinel type catalysts were prepared by...

Reaction conditions effect and pathways in the oxidative steam reforming of raw bio-oil on a Rh/CeO₂-ZrO₂ catalyst in a fluidized bed reactor

A reaction scheme has been proposed for the oxidative steam reforming (OSR) of raw bio-oil on a Rh/CeO₂-ZrO₂ catalyst, based on the study of the effect reaction conditions (temperature, space time, oxygen/carbon ratio and steam/carbon ratio) have on product yields (H₂, CO, CO₂, CH₄,...
