Performance assessment of a power-to-gas process based on reversible solid oxide cell

引用

Frontiers of Chemical Science and Engineering 2018年第4期12卷 697-707页

作者： hanaa Er-rbib Nouaamane Kezibri Chakib Bouallou Centre for Energy Efficiency of Systems MINES ParisTechPSL Research UniversityParis 75006France

Due to the foreseen growth of sustainable energy utilization in the upcoming years, storage of the excess production is becoming a rather serious matter. In this work, a promising solution to this issue is investigated using one of the most emerging technologies of electricity conversion: reversible solid oxide cells (RSOC). A detailed model was created so as to study the RSOC performance before implementing it in the global co-electrolysis Aspen Plus(TM) model. The model was compared to experimental results and showed good agreement with the available data under steady state conditions. The system was then scaled up to a 10MWco-electrolysis unit operating at 1073 K and 3 bar. The produced syngas is subsequently directed to a methanation unit to produce a synthetic natural gas (SNG) with an equivalent chemical power of 8.3 MWth. Additionally, as a result of a heat integration analysis, the methanation process provides steam and electricity to operate the rest of the units in the process. A final CO2 capture step is added to ensure the required specifications of the produced SNG for gas network injection. Lastly, the overall performance of the power-to-gas process was evaluated taking into account the energy consumption of each unit.

Cancer recurrence and severe side effects of currently being used chemotherapeutic agents reduce their clinical efficacy. Thus, there is a constant need to develop alternative anticancer drugs. Sustainable supply is an important challenge facing marine-based drug discovery. Primmorph, a 3D cell culture system, could provide a sustainable source to produce metabolites for anticancer drugs from marine sponges. In the present work, the anticancer activity of primmorph extracts and mesohyls of Negombata magnifica, Hemimycle arabica, Crella spinulata, and Stylissa carteri sponges was evaluated. Antiproliferative activity was studied in terms of cytotoxicity, colony formation, cell cycle, and apoptosis. Migration was assessed by migration assay and matrix metalloproteinase activity. The expression of proliferation and migration-related genes was analyzed using real time PCR. Migration and proliferation activities of HepG2 cells were inhibited by treatment with primmorph extracts and mesohyls of N. magnifica, H. arabica, and C. spinulata. The mesohyl of S. carteri did not show any anticancer activity although the primmorph extract led to cell cycle arrest. Among the selected sponge species, the primmorph extract of C. spinulata was the most promising anticancer agent regarding antiproliferative and antimigratory activities. In addition, primmorph extracts have the advantage of working under welldefined and controlled conditions, which allows the easy application as a bioreactor.

Electrodeposited Pt and Pt-Sn nanoparticles on Ti as anodes for direct methanol fuel cells

引用

燃料化学学报 2009年第3期37卷 346-354页

作者： hanaa B HASSAN Department of Chemistry Faculty of ScienceUniversity of Cairo

Electro-oxidation of methanol was studied on titanium supported nanocrystallite Pt and Ptx-Sny catalysts prepared by electrodeposition techniques. Their electro-catalytic activities were studied in 0.5 mol/L H2SO4 and compared to those of a smooth Pt, Pt/Pt and Pt-Sn/Pt electrodes. Platinum was deposited on Ti by galvanostatic and potentiostatic techniques. X-ray diffractometer (XRD) and energy dispersive X-ray (EDX) techniques were applied in order to investigate the chemical composition and the phase structure of the modified electrodes. Scanning electron microscopy (SEM) was used to characterize the surface morphology and to correlate the results obtained from the two electrochemical deposition methods. Results show that modified Pt/Ti electrodes prepared by the two methods have comparable performance and enhanced catalytic activity towards methanol electro-oxidation compared to Pt/Pt and smooth Pt electrodes. Steady state Tafel plots experiments show a higher rate of methanol oxidation on a Pt/Ti catalyst than that on a smooth Pt. Introduction of a small amount of Sn deposited with Pt improves the catalytic activity and the stability of prepared electrode with time as indicated from the cyclic votlammetry and the chronoamperometric experiments. The effect of variations in the composition for binary catalysts of the type Ptx-Sny/Ti towards the methanol oxidation reaction is reported. Consequently, the Ptx-Sny/Ti (x∶y (8∶1), molar ratio) catalyst is a very promising one for methanol oxidation.

“义”的概念是《孟子》中提出的重要美德之一。本文关注孟子所说的“义”的实践意义,包括“义”与人际关系处理(与自己、与家庭以及与政治活动的关系);“义”作为德性(“四端”之中的“义”,“义”是外在还是内,“义”与“礼”的关系,... 详细信息

“义”的概念是《孟子》中提出的重要美德之一。本文关注孟子所说的“义”的实践意义,包括“义”与人际关系处理(与自己、与家庭以及与政治活动的关系);“义”作为德性(“四端”之中的“义”,“义”是外在还是内,“义”与“礼”的关系,“义”与“气”的关系,如何接受礼物才是遵循‘义’);以及“义”如何可以帮助解决当前社会面临的一些问题(包括政治问题、经济问题、分配公平问题、社会问题等等)。在《论语》中,孔子只被描述为教育家。他希望他的追随者成为能够为社会做出贡献的“全面的人”,因此他教给他们各种侧重于基本素质的科目。社会关系中的每个“名”都带有一系列的责任和义务。这些“名”包括君、臣、父、子、兄、弟等等,拥有这些头衔的人必须正确履行自己的角色和职责。这是对孔子正名学说的解释。孟子是东亚最受欢迎、最著名和最伟大的哲学家之一,在儒家学派的历史上,他发展了孔子在公元前6至5世纪创立并为中国人实践了两千年的人生哲学。虽然随着时间的推移,儒家学说发生了变化,但它仍然是中国教育的支柱和中国价值观的根源。孔孟重视以“义”的概念指导人与人、父子、兄弟、君臣的关系。本文将探讨孟子的“义”概念,以及实践“义”对人、家庭、国家和国家的意义。在《告子上》第10节中,孟子陈述了“义”对每个人的重要性。他举了一个例子,如果人有两个选择,“命”或“义”,只能选择一个,他将如何抉择?这种选择将反映和评估人类的行为。如果选择“义”,则不止要自己实践,还要必须和别人一起实践。如果选择“命”,则很可能不仅不实践“义”,还会假装实践“义”。《离娄下》中的齐人就是这样,他没有实践‘义’,反而跟妻妾假装自己有“义”,这就是小人的做法。小人会选择“命”,而君子的“义”就是命。在《尽心上》第15节中,他解释了“生而有之”的含义,即人类无需先前学习即可完成的事情或无需思考即可获得的知识。从这一点来说,可以说人类天生就有仁义。孝敬父母和尊重兄长是其表现。孟子也将孝敬父母称为仁,将尊敬长辈称为义。这意味着每个人都生来都有仁义,“义”作为“四端”之一(《公孙丑上》第6节),随着修炼而成长。孟子在《离娄下》第5节中描述了统治者对平民的影响。庶民随君而行。如果君王实践了“义”,平民就会实践“义”。普通人总是仰慕和效法处在高位的人。当孟子和告子争论人性时,他支持了这种平民跟随领导者的想法。《告子上》第6节提出,当百姓饥寒交迫时,王不能要求百姓仁义,首先,君王必须帮助平民在繁荣时期和匮乏时期都能获得最低限度的食物和衣服,关于“义”的修行将在人民经济安定后开始。如果统治者食用自己耕种的食物并与平民并肩工作,那么他是否正确实践了“义”?如果君子吃他自己种的粮食,穿他自己织的布,那么他是否正确地实践了“义”?关于这组问题,《滕文公上》第四节中,孟子在与陈良(许行的弟子)的讨论中给出的答案。他钦佩统治者能完成他的下属应该完成的任务,他也很钦佩陈良的老师许行,他以自己种植的庄稼为食,穿着短褐衣服,但若君子忙于耕作,君王忙于做饭,谁来管理百姓的事?谁在乎人的道德和教育?孟子告诉陈良,有两类人,用双手工作的人和用头脑工作的人,用头脑做事的人必须带领用双手做事的人,这样才能实现互利共赢。同时,这两种人之间的关系必须遵循“义”。为什么君子去见君王是不对的?孟子在《滕文公下》和《万章下》回答了这个问题。《滕文公下》中提到有种说法认为凡是见君王的人都必须同意君王的说法,使君王不怒,这其实不是正道。君子有道,如果他们看到国王放弃了道,他们必须询问并引导他回到道上。如果不是谢柳、段干木那样的紧急情况,君子是不愿见君王的。但是,如果君子担任大臣,他必须去朝廷做他的工作。君子之间的尊重,必须是相互的、平等的。孔子不在的时候,阳货送他礼物,孔子并没有直接去拜见阳货,而是一直等到阳货出门(才去回礼)。孟子和万章之间的另一场争论是关于统治者召见读书人的原因。万章认为,君王召见读书人的原因是他受人尊敬、见多识广。孟子拒绝了这个论点,因为如果读书人是值得和知识渊博的,那么君主怎么能召唤他?学习者应该尊重老师。在《离娄上》第27节中,孟子概述了各种美德的重要性。他首先解释说,为父母服务是最高层次的“仁”。其次是'义',如果弟弟跟随并尊重他的哥哥,那就是“义”。在我看来,以仁为本,就是立德之本。如果这个人不是人,就不需要美德。人若不仁,勿行“义”,无礼无智。根据孟子的理论,在“仁”之后,“义”是第二重要的美德。这就是说,如果一个人有仁,但不运用“义”,他将无法获得礼节和智慧。仁、义、智、礼,发于人之四肢,生于四端之心。四肢会随着时间而增长,但四端不会。你必须找到一种技术来培育和种植它们(《公孙丑上》第6节)。如果这个人成功地培植了“四端”,他会在他所说的一切中遵循它们。他采取的每一个行动都会跟随他们。,没有人能阻止他。但是,如果他不这样做,他将
