Insights into the Nature of the Active Sites of Pt-WOx/Al2O3 Catalysts for Glycerol Hydrogenolysis into 1,3-Propanediol
(MDPI, 2021-09-27)
The chemo-selective hydrogenolysis of secondary hydroxyls is an important reaction for the production of biomass-derived α,ω-diols. This is the case for 1,3-propanediol production from glycerol. Supported Pt-WOx materials ...
Integrated Environmental and Exergoeconomic Analysis of Biomass-Derived Maleic Anhydride
(Wiley, 2022-09)
Life cycle analysis and exergy analysis are applied to compare the production of maleic anhydride from different feedstock, both biomass- and petrochemical-derived raw materials, in order to evaluate the sustainability of ...
Effect of atomic substitution on the sodium manganese ferrite thermochemical cycle for hydrogen production
(Elsevier, 2022-10)
This work presents the effect of atomic substitution on the MnFe2O4-Na2CO3 thermochemical cycle for H-2 production. The non-oxidative decarbonation/carbonation reaction of the MnFe2O4-Na2CO3 mixture is investigated as the ...
Influence of Lewis acidity and CaCl2 on the direct transformation of glucose to 5-hydroxymethylfurfural
(Elsevier, 2021-06-11)
[EN] Nb-Zr oxides were evaluated for glucose dehydration to 5-hydroxymethylfurfural. A linear relationship was found between the amount of acid sites and niobium content. Pure Nb2O5 showed the highest acid concentration ...
New insights into Mn2O3 based metal oxide granulation technique with enhanced chemical and mechanical stability for thermochemical energy storage in packed bed reactors
(Elsevier, 2022-06-14)
[EN] High temperature thermochemical energy storage still requires a significant research effort. Most of the research has been carried out with materials at lab-scale, and proper material fabrication techniques need to ...
Ni-Cu bimetallic catalytic system for producing 5-hydroxymethylfurfural-derived value-added biofuels
(ACS, 2020-05-29)
Biorefineries can be a good alternative to cover the current needs of energy, such as transportation fuels and also fine chemicals. 5-hydroxymethylfurfural (HMF) can be obtained directly from biomass, and it is considered ...
Influence of morphology of zirconium-doped mesoporous silicas on 5-hydroxymethylfurfural production from mono-, di- and polysaccharides
(Elsevier, 2020-02-21)
[EN] Different zirconium-doped mesoporous silicas (Zr-KIT-6, Zr-SBA-15, Zr-MCM-41 and Zr-HMS) were synthesized and evaluated in the glucose dehydration to 5-hydroxymethylfurfural (HMF). A Si/Zr molar ratio of 5 was chosen ...
