The effect of catalyst loading in the Aqueous Phase Reforming (APR) bio-oil aqueous fraction has been studied with a Ni-Co/Al-Mg coprecipitated catalyst. Because high content water fraction, APR could be useful process to convert this into valuable products. Experiments continuous feeding solution acetol, butanol and acetic acid as only compound, together simulated real bio-oil, were carried ou...

Lindberg (I) has presented evidence for the occurrence of 1,2propanediol phosphate in beef brain. This compound has also been reported to occur in other tissues (2-4). However, the structure, metabolism, and biological significance of this compound is unknown. Groth et al. (5) have reported that (Y-labeled pyruvate is incorporated into propanediol-P’ under anaerobic conditions in fluoride-inhib...

The vapour phase selective conversion of glycerol to acetol at normal atmospheric pressure in a fixed-bed micro reactor was investigated over SO4 2 and WOx promoted ZrO2 and M-ZrO2 (M = Al2O3 or TiO2) solid acid catalysts. The investigated sulfate and tungstate ion promoted zirconia-based catalysts were prepared by both coprecipitation and impregnation methods and calcined at 923 K. The synthes...

acetol was an intermediate in the metabolism of acetone by an unidentified soil diphtheroid. Because of the divergence of these results from those previously reported for R. gelatinosa, the photosynthetic metaboljsm of acetone was reinvestigated by means of a more direct approach. In addition to the two pathways indicated above, a third variation is postulated in which cleavage of acetone to CZ...

In this study, we investigated different metal pairings of Au nanoparticles (NPs) as potential catalysts for glycerol dehydration for the first time. All of the systems preferred the formation of hydroxyacetone (HYNE). Although the bimetallics that were tested, i.e., Au NPs supported on Ni, Fe and Cu appeared to be more active than the Au/SiO2 system, only Cu supported Au NPs gave high conversi...

The title compound, (C(21)H(22)P)(2)[Cu(2)I(4)], prepared from reaction between copper powder, iodine and isopropyl triphenyl-phospho-nium iodide in hydroxy-acetone (acetol), shows an already known Cu(2)I(4) (2-) anion with a planar conformation [Cu-I range = 2.5108 (3)-2.5844 (3) Å and I-Cu-I range = 110.821 (10)-125.401 (10)°].

Background A future bioeconomy relies on the efficient use of renewable resources for energy and material product supply. In this context, biorefineries have been developed and play a key role in converting lignocellulosic residues. Although a holistic use of the biomass feed is desired, side streams evoke in current biorefinery approaches. To ensure profitability, efficiency, and sustainabilit...
