Catalytic tri-reforming of glycerol for hydrogen generation

Abstract

Tri-reforming of glycerol has been carried out, for the first time, on CeO_2,ZrO₂and CeO₂-ZrO₂ supported 10 wt.% Ni catalysts. The catalysts have been characterized by nitrogen adsorption, X-ray diffraction, temperature programmed reduction, scanning electron microscopy, Raman spectroscopy and X-ray photoelectron spectroscopy and tested for glycerol tri-reforming at atmospheric pressure and 673-1073 K. Ni/CeO₂-ZrO₂ has shown 95% of thermodynamic limit for hydrogen production, at 873 K. Also, the catalyst shows good stability.
