      The conversion of glycerol in gas phase and atmospheric pressure has been investigated over 10 wt.% Ni/γ-Al2O3 catalyst. The catalysts were prepared with nickel nitrate and pre-treated with hydrogen in the range of 623–1073 ...
    • Influence of copper on nickel-based catalysts in the conversion of glycerol 

      Miranda Morales, Bárbara C.; Chimentao, Ricardo J; Szanyi, J; Braga, A.H.; Santos, Jeannette B O; Gispert Guirado, Francesc; Llorca Piqué, Jordi; Medina Cabello, Francisco (2015-05-01)
