| 1 | Properties and Structures of Bi_2O_3-B_2O_3-TeO_2 Glass显示文摘Glass formation range of Bi2O3—B2O3—TeO2 system has been investigated(B2O3 < 40 mol%).Four glasses with compositions xBi2O3—3OB2O3—(70—x)TeO2(x = 40,50,60 and 70 mol%) have been prepared by using melt quenching technique.The effect of Bi2O3 content on thermal stability,optical properties and structures of these four Bi2O3—B2O3—TeO2 glasses is systematically investigated by inductive coupled plasma emission spectrometer(ICP),differential scanning calorimetry(DSC),Raman spectra and X-ray photoelectron spectroscopy(XPS).It is found that the density,refractive index and optical basicity increase with increasing Bi2O3.The Raman spectra and XPS spectra show that the glass network is mainly constituted by the[BiO6] octahedron,[TeO4]trigonal bipyramidal,[TeO3]trigonal pyramid,[BO3]trigonal pyramid and[BO4]tetrahedron structural units.With increasing Bi2O3,the coordination number around B atom changes from 3 to 4 and [TeO4]units are converted to[TeO3]units.Bi5+ ions may exist in Bi2O3—B2O3—TeO2(BBT) system and their amount grows with increasing Bi2O3 content. | Guoying Zhao Ying Tian Huiyan Fan Junjie Zhang Lili Hu | 2013 | Journal of Materials Science & Technology2013，29，3： | 2 |

| 4 | Improving hydrocarbons production via catalytic co-pyrolysis of torrefied-biomass with plastics and dual catalytic pyrolysis显示文摘To increase the low yield and selectivity of aromatic hydrocarbons during the biomass pyrolysis process,we torrefied the biomass and then co-pyrolyzing with plastics such as high-density polyethylene(HDPE),polystyrene(PS),ethylene-vinyl acetate(EVA)and polypropylene(PP)and also single and dual catalyst layouts were investigated by Py-GC/MS.The results showed that non-catalytic fast pyrolysis(CFP)of raw bagasse(RBG)generated no aromatics.After torrefaction non-CFP of torrefied bagasse(TBG)generated low aromatic yield.Indicating that torrefaction would enhance the proportion of aromatics during the pyrolysis process.The CFP of TBG_(200℃)and TBG_(240℃)over ZSM-5 produced the total aromatic yield of 1.96 and 1.88 times higher,respectively,compared to non-CFP of TBG.Furthermore,the addition of plastic could increase H/Ceff ratio of the mixture,consequently,increase the yield of aromatic compounds.Among the various torrefied-bagasse/plastic mixtures,the CFP of TBG/EVA(7:3 ratio)mixture generated the highest the total aromatic yield of 7.7 times more than the CFP of TBG alone.The dual catalyst layout could enhance the yield of aromatics hydrocarbons.The dual-catalytic co-pyrolysis of TBG_(200℃)/plastic(1:1)ratio over USY(ultra-stable Y zeolite)/ZSM-5,improved the total aromatics yield by 4.33 times more than the catalytic pyrolysis of TBG_(200℃)alone over ZSM-5 catalyst.The above results showed that the yield and selectivities of light aromatic hydrocarbons can be improved via catalytic co-pyrolysis and dual catalytic co-pyrolysis of torrefied-biomass with plastics. | Peter Keliona Wani Likun Huiyan Zhang Yuyang Fan | 2022 | Chinese Journal of Chemical Engineering2022，35，2： | 0 |
