| 1 | 帕克活性生物砂滤脱氮的四年运行经验显示文摘由于执行新的氮排放标准,位于鹿特丹西部Vlaardingen地区的排水厂'De Groote Lucht'需要改扩建以达到新要求。该厂在干旱季水量是4,350m3/h,最大水量为12,000m3/h。为了达到总氮的严格要求(总氮年平均小于10mg/L),该排水厂在1999年增设了Astrasand活性生物砂滤床作为脱氮后处理。该系统既能达到很高的脱氮效率,又能很好的去除SS。这篇文章报道了四年连续运行的条件和结果。 | Kramer J.P.

| 2 | Active oxygen center in oxidative coupling of methane on La_(2)O_(3) catalyst显示文摘La_(2)O_(3) catalyzed oxidative coupling of methane(OCM) is a promising process that converts methane directly to valuable C_(2)(ethylene and ethane) products. Our online MS transient study results indicate that pristine surface without carbonate species demonstrates a higher selectivity to C_(2) products, and a lower light-off temperature as well. Further study is focused on carbonate-free La_(2)O_(3) catalyst surface for identification of active oxygen species associated with such products behavior. XPS reveals unique oxygen species with O 1 s binding energy of 531.5 e V correlated with OCM catalytic activity and carbonates removal. However, indicated thermal stability of this species is much higher than the surface peroxide or superoxide structures proposed by earlier computation models. Motivated by experimental results,DFT calculations reveal a new more stable peroxide structure, formed at the subsurface hexacoordinate lattice oxygen sites, with energy 2.18 e V lower than the previous models. The new model of subsurface peroxide provides a perspective for understanding of methyl radicals formation and C_(2) products selectivity in OCM over La_(2)O_(3) catalyst. | Xiaohong Zhou Yaoqi Pang Zebang Liu Evgeny I.Vovk Alexander Pvan Bavel Shenggang Li Yong Yang | 2021 | Journal of Energy Chemistry2021，30，9： | 2 |
