Biomass pyrolysis improved when using calcined catalysts, with an increase in biogas yields (5.4 and 5.2% increase for dolomite and clinoptilolite, respectively), while non-calcined catalysts promoted higher condensate yields with an increment of 21.3 and 16.2% for dolomite and clinoptilolite compared with the calcined catalyst tests. Characterization of the condensate fraction with GC-MS showed formation of less oxygenated organic molecules in the pyrolysis tests, with an increase of 66% and 139% in the relative areas of organic compounds with an atomic content lower than 20%, when calcined dolomite and clinoptilolite were used, respectively, compared with the non-calcined catalysts. A prominent formation of Limonene was also observed. Syngas analysis with GC-TCD showed calcined clinoptilolite promoted higher...

Research paper thumbnail of Dehydration of fructose over thiol– and sulfonic– modified alumina in a continuous reactor for 5–HMF production: Study of catalyst stability by NMR

This material has shown to have an enhanced catalytic performance with grafted organic groups and showed an improved stability. The prepared material has shown to have several OH groups and an enhanced surface acidity. The alumina acidity was improved by incorporating thiol groups by grafting method, which promotes the tautomerization of fructose to its furanose form. Furthermore, the grafting of sulfonic groups catalyzes its dehydration. The modified alumina was thermally treated up to 200°C to improve the functional groups stability. After, this modified material was packed into a continuous reactor system, designed and built by this group, to obtain 5-hydroxymethylfurfural (5-HMF) from fructose dissolved in a single-phase solution of tet-rahydrofuran (THF) and H 2 O (4:1 w/w). The catalytic activity of this material was evaluated by the reaction of fructose dehydration at different reaction temperatures (60, 70, 80 and 90°C). Fructose conversion and se-lectivity towards 5-HMF were determined by high performance liquid chromatography (HPLC), obtaining 95% and 73% respectively for the highest temperature. The catalyst showed an efficient stability after 24 h in continuous flow at 70°C. The loss of sulfur content was 15%, but the fructose conversion yield and the selectivity to 5-HMF after 24 h of continuous reaction did not undergo significant changes (less than 5%). The nuclear magnetic resonance (NMR) tests confirmed the presence of the thiol and sulfonic groups before and after 24 h of reaction, as well as the conservation of the same structure, demonstrating the efficient catalytic performance of the material. The catalysts were characterized by nitrogen adsorption/desorption, X-ray diffraction and infrared (IR) spectroscopy. Also, before and after use by utilizing elemental analysis and 1 H-13 C cross-polarization magic-angle spinning (CPMAS) and dynamic-nuclear polarization (DNP)-enhanced 1 H-13 C and 1 H-29 Si CPMAS as well as directly excited 29 Si magic-angle spinning (MAS) NMR methods in solid-state.

Research paper thumbnail of Magnetic nanofibrous materials based on CMC/PVA polymeric blends

The nanofibrous materials were obtained from the electrospinning of SMON-CMC/PVA blends with different SMON content, applying a constant tension of 15 kV. The synthesized samples were analyzed by transmission electron microscopy, scanning electron microscopy, attenuated total reflectance Fourier transform infrared, Raman and X-Ray photoelectron spectroscopy, as well as static magnetic measuring. Our experimental findings indicate that nanofibers' diameter decreases as SMON content in the electrospun polymeric blends is increased, since these magnetic nanoparticles diminish the interactions between PVA and CMC molecules, which improves their spinnability. Moreover, the spatial distribution of SMON in the fibers provides to the synthesized nanof...
