abstract = {The effect of catalyst loading in the Aqueous Phase Reforming (APR) of bio-oil aqueous fraction has been studied with a Ni-Co/Al-Mg coprecipitated catalyst. Because of the high content of water in the bio-oil aqueous fraction, APR could be a useful process to convert this fraction into valuable products. Experiments of APR with continuous feeding of aqueous solution of acetol, butanol and acetic acid as the only compound, together with a simulated and a real aqueous fraction of bio-oil, were carried out. Liquid products in the liquid effluent of the APR model compounds were quantified and the reaction pathways were revised. The increase of catalyst loading produced an increase of gas production and a gas with higher alkanes content. Acetol was the compound with the highest reactivity while the conversion of acetic acid was very low. The presence of acetic acid in the feed caused catalyst deactivation.},

abstract = {This work assesses the effects of various process temperatures (700, 750, and 800 °C) and equivalence ratio (0.25; 0.30 and 0.35) on gasification of grapefruit (Citrus x paradisi) solid waste (GSW) in a fluidized bed reactor. The experimental results permit the construction and fit tridimensional chart to assess the studied main output variables' behavior for the simultaneous variation of equivalence ratio and process temperature. The better producer gas composition for the grapefruit solid waste gasification was obtained for a process temperature of 800 °C and 0.25 equivalence ratio; the gas yields around 67%, with LHV of 4389 kJ/Nm3, within the spectrum of values reported for other lignocellulosic residues. According to the obtained study results, GSW presents a valuable renewable energy resource for agroindustry. For operation parameters assessed, could be potentially produced 3.49 GJ of thermal energy per ton of GSW gasified.},

abstract = {The present work studied the stability and reusability of Ni/Al-Fe catalyst in the aqueous phase hydrogenolysis of glycerol without external hydrogen addition. The catalyst based on 28 molar % of Ni with 3/1 molar ratio of Al/Fe was prepared through co-precipitation. This catalyst presented the best performance in our last study which compares several Ni/Al-Fe catalysts with different molar ratios of Al/Fe. To see the influence of the pressurized water on the physicochemical characteristics of Ni/Al-Fe catalyst, a test of up to 9 h has been carried out. Fresh and used catalysts were characterized by various techniques: X-ray Diffraction (XRD), N2-physisorption, field emission scanning electron microscopy (FESEM) and STEM. Glycerol conversion and carbon yield to gases and liquids did not vary significantly when compared at 3 h and 9 h. Furthermore, the morphology of the catalyst remains stable after continuous recycling under severe hydrothermal conditions. The nickel rich phase of the catalyst, which was determined by XRD and scanning transmission electron microscopy (STEM) techniques, showed a stable size after 9 h under reaction.},

abstract = {This work presents a novel catalyst preparation method and the optimization of operation conditions for an effective NO3− conversion with a high selectivity and stability that guarantee water quality for human consumption. Catalytic reduction of NO3− and NO2− was carried out with Pd supported on In2O3 under mild operation conditions (25 °C, 1 atm) with H2 and CO2 as reducing and acidifying agents, respectively. The catalyst was used in batch experiments showing the suppression of NO2− accumulation and low NH4+ selectivity at acid pH. Long-term experiments were carried out with Pd on $gamma$-Al2O3 spheres covered with In2O3. This catalyst presented a high stability during more than 700 h. A concentration of NO3− below 50 mg/L was achieved, producing less than 0.5 mg/L of NH4+ as reaction by-product by a strict limitation of the H2 fed and controlling several operating conditions.},
