Conversion of decalin and 1-methylnaphthalene over AlSBA-15 supported Pt catalysts

Bimetallic platinum/iridium modified mesoporous catalysts applied in the hydrogenation of HMF

“…was already explained in terms of the presence of electronic deficient species that avoid the irreversible adsorption of the hydrocarbon compounds. These sites are also more resistant to poisoning and coke formation [37][38][39][40]. In this way, Nishimura et al [9] affirm that the formation of the electronically poor states in the noble metal in the alloy plays a crucial role in the activation of H2 molecules and/or the enhancement of the hydrogenation reaction pathway.…”

Ring opening of decalin over bifunctional Ni–W carbide/Al2O3–USY catalysts and monofunctional acid Ni–W oxide/Al2O3–USY

“…Recently, the bifunctional catalysts 1,7,8,10,[12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] has been used in the ring opening of naphthenes which showed good performance because of its more acid sites and higher hydrogenation on metal sites. The studies about bifunctional catalysts mainly focused on some noble metal catalyst, 1,[8][9][10]12,[14][15][16][18][19][20][21][24][25][26][28][29][30][31] which are easier sulfur poisoning.…”

Influence of Ti Incorporation to Bimetallic Mesoporous Carbon in the Production of 2,5-Dimethylfuran from Biomass Derivatives

“…However, here we observe that using a slightly acidic support, such as TiC, we obtained better results in terms of DMF performance. As we said earlier, the acidity of the support generates electron deficient species that prevent deep hydrogenation or opening of the furan ring [65][66][67][68][69][70]. Despite of the higher acidity values obtained by FTIR of Py for the catalyst modified with Ti, C-C bond cleavage of tertiary carbon of the HMF to the formation of FA products was not observed.…”
