Hydrogen Pressure as a Key Parameter to Control the Quality of the Naphtha Produced in the Hydrocracking of an HDPE/VGO Blend
(MDPI, 2022-05-16)
The hydrocracking of high-density polyethylene (HDPE) blended with vacuum gas oil (VGO) has been studied to assess the effect of H2 pressure on the yield and composition of the products and with the aim of obtaining ...
Pedagogical Approaches for Sustainable Development in Building in Higher Education
(MDPI, 2021-09-13)
Education for sustainable development (ESD) is one of the great challenges that university faculties have to face. Therefore, a multidisciplinary team from the faculty of Engineering of Gipuzkoa (EIG) at the University of ...
Environmental Assessment of University Campuses: The Case of the University of Navarra in Pamplona (Spain)
(MDPI, 2021-08-01)
Current European environmental sustainability standards call for achieving a reduction in energy consumption and CO2 emissions for a horizon set in the year 2050. It has been verified that buildings and cities have a higher ...

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 ...
Extraction of flavonoid compounds from bark using sustainable deep eutectic solvents
(Elsevier, 2021-12)
[EN] The use of green solvents in extraction processes, especially for applications of lignocellulosic biomass, has been extensively studied over the last years. Among the range of different green solvents, deep eutectic ...
Renewable biopolyols from residual aqueous phase resulting after lignin precipitation
(ACS, 2021-02-19)
The aim of this work was to obtain two biopolyols from the liquid residue resulting from the precipitation of lignin contained in two different black liquors, Eucalyptus globulus organosolv black liquor (EOBL) and Pinus ...
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 ...
