Effect of nickel loading approaches on the structure and hydrodeoxygenation performance of Ni/Al-SBA-15

Boosting the Hydrodeoxygenation Activity and Selectivity of Ni/(M)-SBA-15 Catalysts by Chemical Alteration of the Support

“…Li et al tested the performance of Ni/Al-SBA-15 catalysts in eugenol HDO and observed that the activity and selectivity of the catalysts were affected by both the quantity of acid sites and the dispersion of nickel species. 26,27 Finally, NiNb and Ni−ZrO 2 catalysts supported on SBA-15 silica also showed high activity in the HDO of anisole and guaiacol, respectively, with high selectivity toward CHA production. 28,29 The activity of the NiNb/SBA-15 was explained in terms of acidity, metal surface exposure, and reducibility as a function of the interaction between the phases present, 28 while the good activities and selectivities toward total deoxygenation obtained for the silica supported Ni−ZrO 2 catalysts were associated with the proximity between Ni and ZrO 2 particles when confined in the silica mesopores.…”

“…Gbadamasi et al found that Ni/Al-SBA-15 catalysts were promising for HDO of dibenzofuran (DBF) into hydrocarbons, observing a synergetic effect between Ni and the Al-SBA-15 support. Li et al tested the performance of Ni/Al-SBA-15 catalysts in eugenol HDO and observed that the activity and selectivity of the catalysts were affected by both the quantity of acid sites and the dispersion of nickel species. , Finally, NiNb and Ni–ZrO 2 catalysts supported on SBA-15 silica also showed high activity in the HDO of anisole and guaiacol, respectively, with high selectivity toward CHA production. , The activity of the NiNb/SBA-15 was explained in terms of acidity, metal surface exposure, and reducibility as a function of the interaction between the phases present, while the good activities and selectivities toward total deoxygenation obtained for the silica supported Ni–ZrO 2 catalysts were associated with the proximity between Ni and ZrO 2 particles when confined in the silica mesopores . Summarizing the above results, it can be noted that, in general, bifunctional metal-acid catalysts show catalytic performance in HDO superior to that of their metallic counterparts supported on unmodified SBA-15 silica.…”
