Activity and stability of different Fe loaded primary catalysts for tar elimination
(Elsevier, 2022-06)[EN] The performance of olivine, dolomite and gamma-alumina primary catalysts was evaluated in the continuous tar elimination process in which toluene was selected as the biomass gasification tar model compound. Iron was ... -
Characterization of the Compounds Released in the Gaseous Waste Stream during the Slow Pyrolysis of Hemp (Cannabis sativa L.)
(MDPI, 2022-04-27)This study aims to characterize and valorize hemp residual biomass by a slow pyrolysis process. The volatile by-products of hemp carbonization were characterized by several methods (TGA, UV-VIS, TLC, Flash Prep-LC, UHPLC, ... -
Combustion of a Solid Recovered Fuel (SRF) Produced from the Polymeric Fraction of Automotive Shredder Residue (ASR)
(MDPI, 2021-11-03)The use of alternative fuels derived from residues in energy-intensive industries that rely on fossil fuels can cause considerable energy cost savings, but also significant environmental benefits by conserving non-renewable ... -
Enzymatic upgrading of nanochitin using an ancient lytic polysaccharide monooxygenase
(Springer Nature, 2022-08-15)Numerous enzymes have the potential to upgrade biomass, converting it into high-tech materials for new applications. However, the features of natural enzymes often limit their use beyond chemical conversion of the substrate. ... -
Fe/Olivine As Primary Catalyst in the Biomass Steam Gasification in a Fountain Confined Spouted Bed Reactor
(Elsevier, 2021-07-25)The performance of Fe/olivine catalysts was tested in the continuous steam gasification of sawdust in a bench scale plant provided with a fountain confined conical spouted bed reactor at 850 degrees C. Olivine was used as ... -
Fractionation of lignin using organic solvents: A combined experimental and theoretical study
(Elsevier, 2021-01-31)Refining of industrial lignin to produce homogeneous fractions is essential for high-value applications. However, the understanding of key interactions between a variety of solvents with lignin polymer is still uncertain. ... -
Functionalization of Cellulose Nanocrystals in Choline Lactate Ionic Liquid
(MDPI, 2016-06)Cellulose nanocrystals (CNCs) are valuable nanomaterials obtained from renewable resources. Their properties make them suitable for a wide range of applications, including polymer reinforcement. However, due to their highly ... -
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 ... -
Hydrophobization and Photo-Stabilization of Radiata Pinewood: The Effect of the Esterification on Thermal and Mechanical Properties
(MDPI, 2020-10-24)Wood protection through chemical modification has received increasing interest over the last decades due to the environmental issues related to conventional biocides or protecting products. Consequently, a wide range of ... -
Mixed Ionic-Electronic Conducting Membranes (MIEC) for Their Application in Membrane Reactors: A Review
(MDPI, 2019-03-01)Mixed ionic-electronic conducting membranes have seen significant progress over the last 25 years as efficient ways to obtain oxygen separation from air and for their integration in chemical production systems where pure ... -
Nucleation of Poly(lactide) on the Surface of Different Fibers
(ACS Publications, 2019-08-14)The nucleation process of poly(lactide) (PLA) on a series of fibers was studied by means of in-situ Polarized Optical Microscope (POM) during crystallization. Several synthetic and natural fibers (PLLA stereocomplex fibers ... -
Tailoring the isothermal crystallization kinetics of isodimorphic poly (butylene succinate-ran-butylene azelate) random copolymers by changing composition
(Elsevier, 2019-10-07)A detailed isothermal crystallization study of biobased and biodegradable isodimorphic poly (butylene succinate-ran-butylene azelate) random copolyesters (PBS-ran-PBAz) with a wide composition range has been carried out ... -
The Effect of Titanium Dioxide Surface Modification on the Dispersion, Morphology, and Mechanical Properties of Recycled PP/PET/TiO2 PBNANOs
(MDPI, 2019-10-16)Titanium dioxide (TiO2) nanoparticles have recently appeared in PET waste because of the introduction of opaque PET bottles. We prepare polymer blend nanocomposites (PBNANOs) by adding hydrophilic (hphi), hydrophobic (hpho), ...
