1Al_2O_3基Ni-Cu双金属催化剂上乙酰丙酸氢解(英)显示文摘Inexpensive γ-alumina-based nickel-copper bimetallic catalysts were studied for the hydrogenolysis of levulinic acid,a key platform molecule for biomass conversion to biofuels and other valued chemicals,into γ-valerolactone as a first step towards the production of 2-methyltetrahydrofurane.The activities of both monometallic and bimetallic catalysts were tested.Their textural and chemical characteristics were determined by nitrogen physisorption,elemental analysis,temperature-programmed ammonia desorption,and temperature-programmed reduction.The monometallic nickel catalyst showed high activity but the highest bγ-product production and significant amounts of carbon deposited on the catalyst surface.The copper monometallic catalyst showed the lowest activity but the lowest carbon deposition.The incorporation of the two metals generated a bimetallic catalyst that displayed a similar activity to that of the Ni monometallic catalyst and significantly low bγ-product and carbon contents,indicating the occurrence of important synergetic effects.The influence of the preparation method was also examined by studying impregnated- and sol-gel-derived bimetallic catalysts.A strong dependency on the preparation procedure and calcination temperature was observed.The highest activity per metal atom was achieved using the sol-gel-derived catalyst that was calcined at 450 ℃.High reaction rates were achieved;the total levulinic acid conversion was obtained in less than 2 h of reaction time,yielding up to 96%γ-valerolactone,at operating temperature and pressure of 250 ℃ and 6.5 MPa hydrogen,respectively.Iker Obregón Eriz Corro Urko Izquierdo Jesus Requies Pedro L.Arias 2014催化学报2014,35,5:8
2Use of residual lignocellulosic biomass for energetic uses and environmental remediation through pyrolysis显示文摘This study analyzes the potential of an agricultural residue,hazelnut shells,as raw material in a combined ther-mochemical process to obtain pyro-gas and biochar for environmental remediation.The novelty of this study relies on the definition of a pyrolytic polygeneration process to simultaneously attain an energy-type product and abiochar to maximize the versatility of the products and their usage.To this aim,the heating value of the gas and its potential to feed a micro combined heat and power(micro-CHP)system was evaluated.Additionally,the resulting biochar was chemically activated and tested as adsorbent for the removal of contaminants from an aqueous solution.Results show that the pyro-gas from the shell-type residue was suitable to be used as feed stream in a micro-CHP unit,which was able to operate near the full-load(91.9%)with electrical and thermal efficiencies of 27.6%and 57.9%,respectively.In the case of the biochar fraction,poor results were found for the char prior to activation.Instead,once it was activated with KOH,the resulting activated carbon presented high effectiveness as adsorbent and complete removal of the measured compound(methylene blue)was achieved.Nezly Martelo Mirari Antxustegi Eriz Corro Marya Baloch Rosaria Volpe Antonio Gagliano Alberto Fichera María Gonzalez Alriols 2022Energy Storage and Saving2022,1,3:0
