Production of hexane from sorbitol in aqueous medium over Pt/NbOPO4 catalyst

Selective C−O Hydrogenolysis of Erythritol over Supported Rh‐ReOx Catalysts in the Aqueous Phase

“…Cyclic compounds (mainly 1,4‐AE) that result from the internal dehydration of ERY in the presence of Rh‐ReO x /TiO 2 and Rh‐ReO x /ZrO 2 were favored under 30 bar of H 2 (13 and 21 %, respectively). These data are consistent with observations during the hydrogenolysis of sorbitol to hexane over Pt/NbOPO 4 at 250 °C in an aqueous medium: it was shown that the oxygenated compounds that result from the dehydration of sorbitol (1,4‐sorbitan, isosorbide, and 2‐(tetrahydrofuran‐2‐yl)ethan‐1‐ol) were the main products under a low H 2 pressure …”

[46] Moreover,t he epimerization of ERY to threitol was higher under 120 bar of H 2 over Rh-ReO x /TiO 2 (selectivity = 14 %) and Rh-ReO x /ZrO 2 (selectivity = 9%)t han that under 30 bar (selectivity = 5%). It was observed previously that the presence of ReO x species enhanced the selective 1,3-isomerization of allylic alcohols [47] and the isomerization of sorbitol to mannitol over PtÀReO x /C.…”

Production of Gasoline Fuel from Alga‐Derived Botryococcene by Hydrogenolysis over Ceria‐Supported Ruthenium Catalyst

“…[8][9][10][11][12][13] However, the production of hydrocarbon-type biogasoline is difficult because of the high oxygen content of lignocellulose and the straight carbon chains of polysaccharides. [14][15][16][17][18][19][20][21][22][23][24] On the other hand, algal biomass is ah ighly promising resourceb ecause of the algae's high biomass productivity and because there is no competition of algal cultivation with food production. [25][26][27][28][29] Amongt he componentso fa lgalb iomass such as triglycerides, polysaccharides, and amino acid, hydrocarbons without aheteroatom, which are produced by some algae species, attractmuch attention because of their similarity to petroleum.…”
