Effect of the composition and acidity of supported sulfide catalysts on their activity and deactivation in guaiacol hydrodeoxygenation

Hydrodeoxygenation of raw bio-oil towards platform chemicals over FeMoP/zeolite catalysts

“…Hence, it can be concluded that catalyst acidity not only plays a determining role in the HDO reaction mechanism [45,59], but also in the deactivation of the catalyst. In this sense, the direct correlation between the catalyst acidity (and the strength of the acidic sites) and the formation of coke has already been established [60]. The results of the previous sections point out that the most acidic catalyst (FeMoP/HY)…”

Mechanistic insights on Ru nanoparticle in situ formation during hydrodeoxygenation of lignin-derived substances to hydrocarbons

“…Both base metal (Ni, Co, W, Mo)-and noble metal (Ru, Rh, Pt, Rh)containing catalysts have been studied extensively for the HDO of bio-oil and model substances such as guaiacol, furfural, eugenol and many others. 6,[12][13][14][15][16][17][18] The application of base metal catalysts in the sulfide form usually requires mixing bio-oil with sulfur-containing middle distillate fractions due to the absence of sulfuric compounds in the bio-oil, which are needed to keep the catalyst activity. However, the resulting water during HDO usually leads to a loss of catalyst activity.…”

“BTX” from Guaiacol HDO under Atmospheric Pressure: Effect of Support and Carbon Deposition

“…Olcese found that Fe/SiO 2 was a potential catalyst for guaiacol hydrodeoxygenation (HDO) . Nikulshin investigated the effect of the composition and the acidity of supporting sulfide catalysts on their activity and deactivation in guaiacol hydrodeoxygenation …”

“…15 Nikulshin investigated the effect of the composition and the acidity of supporting sulfide catalysts on their activity and deactivation in guaiacol hydrodeoxygenation. 16 Comparative research will indicate the role of supports in modifying catalyst morphologies and changing catalytic activity. In this paper, we prepared Ni/Fe/HBeta, Ni/Fe/ZSM-5, Ni/ Fe/HY, Ni/Fe/MCM-41, Ni/Fe/SiO 2 , and Ni/Fe/γ-Al 2 O 3 catalysts and compared their catalytic performance in HDO and transmethylation.…”
