Role of group V elements on the hydrogenation activity of Ni/TiO2 catalyst for the vapour phase conversion of levulinic acid to γ-valerolactone

Autor: Manasa Kandula, Venugopal Akula, Vijay Kumar Velisoju, Naresh Gutta, Ganga Bhavani Peddakasu, Komandur V. R. Chary

Publikováno v: Catalysis Today. 325:68-72

Influence of group V elements such as Ta, Nb and V on the product distribution in the vapour phase hydrogenation of levulinic acid (LA) over Ni/TiO2 catalyst was examined at ambient pressure. The Nb promoted Ni/TiO2 demonstrated a high selectivity to
