    S2(a ) production in the photolysis of reduced sulfides: production chemistry, spectroscopy and interference potential in the LIF detection of OH
    摘要:
    Production of S-2(a(1)Delta, upsilon = 2) has been observed in the UV photolysis of several reduced sulfur compounds by monitoring the f(1)Delta-a(1)Delta (2-3) laser excitation spectrum. There appears to be at least three production mechanisms including reaction of S(D-1) with the precursor. The f-a (2-3) band shows several spectral overlaps with the OH A (2)Sigma-X(2)Pi (1-0) band including the Q(1)1 line. Since a significant fraction of the f-a emission from f(1)Delta (upsilon = 2) overlaps the OH A-X (1-1) and (0-0) bands the potential for a significant 'interference' signal exists if the two species are produced simultaneously.

  • On the Synergism between La2O2S and CoS2in the Reduction of SO2to Elemental Sulfur by CO
    作者:Jianxin Ma、Ming Fang、Ngai Ting Lau

    日期:1996.1
    study of the catalytic reduction of SO2to elemental sulfur by CO in the presence of La2O2S and CoS2, a synergistic effect between the two sulfides was observed which not only increased the catalytic activity but also suppressed the formation of the side-product COS. It was also found that the crystal phase of CoS2, which can be easily reduced by CO, could be retained when La2O2S coexisted even in small
    在我们研究中,在La 2 O 2 S和CoS 2存在下,CO将SO 2还原为元素硫的过程中,发现了两种硫化物之间的协同作用,不仅增加了催化活性,而且抑制了二硫化物的形成。还发现,即使少量共存La 2 O 2 S ,也可以保留容易被CO还原的CoS 2的结晶相。提出了一种基于COS中间机制和远程控制概念的机制。

    In the manufacture of sulphur from hydrogen sulphide by burning a portion thereof to sulphur dioxide and reacting this with the remainder, the reaction is carried out in the presence of a catalyst at a temperature not exceeding 400 DEG C., this being effected by cooling the dioxide prior to the catalytic reaction. In the apparatus shown, hydrogen sulphide is forced by a pump 1 through a three way cock 2 adjusted to supply the required amount to a burner 3 to which air is supplied by a blower 5, the heat of combustion being used to produce steam in a boiler 6. Sulphur dioxide so produced is mixed in a vessel 4 with the remainder of the hydrogen sulphide and passed through a chamber 7 filled, e.g. with bauxite, the sulphur formed being collected in a vessel 8. The waste gases, which may contain some residual sulphur vapour and some of the reacting gases pass through settling chambers 10 or through a second catalytic chamber; removal may be effected by active carbon. Specification 9768/84, [Class 90], is referred to.

    the positive ions and neutral species in glow discharges containing 1.0% each of SO2 and CO in helium and also 1.1% each of SO2 and CO2 in helium. Ion species observed in these mixtures included S+, SO+, SO2+, O+, O2+ C+, CO+, and CO2+ with lesser amounts of SO3+, [CO]2+, SCO+, and [SO·CO]+ (or CS2+). The functional dependencies of the various ion and neutral species on pressure and discharge current
    已经对辉光放电中的正离子和中性物质进行了质谱研究,氦气中 SO2 和 CO 各含 1.0%,氦气中 SO2 和 CO2 各含 1.1%。在这些混合物中观察到的离子种类包括 S+、SO+、SO2+、O+、O2+ C+、CO+ 和 CO2+,以及较少量的 SO3+、[CO]2+、SCO+ 和 [SO·CO]+(或 CS2+)。各种离子和中性物质对 He-SO2-CO 混合物压力和放电电流的函数依赖性与 CO 与放电中形成的 SO 反应生成 CO2 和硫的解释一致。在 He-SO2-CO2 混合物中的测量也表明通过形成 CO2 和 S 去除了 SO2。
  • Reactivity of Fe<sub>2</sub>O<sub>3</sub>and Fe<sub>2</sub>O<sub>3</sub>–Al<sub>2</sub>O<sub>3</sub>Mixture for Reduction of SO<sub>2</sub>with CO
    作者:Tadao Ishii、Ryusaburo Furuichi、Koji Shikano
    DOI:10.1246/bcsj.55.1447
    日期:1982.5
    Catalytic reactivities of α-Fe2O3 powder (−200 mesh) and a α-Fe2O3–γ-Al2O3 powder mixture prepared by mechanical mixing, which were preheated at 360–700 °C, were studied for the reduction of SO2 with CO by means of both a reaction gas-chromatographic technique using CO, SO2, and 2CO–SO2 pulses and the powder X-ray analysis. The reactivity of Fe2O3 decreases with increasing preheating temperature, which is explained on the basis of redox reactions between Fe2O3 and nascent (Fe3O4): 6Fe2O3+2CO→4(Fe3O4)+2CO2 and 4(Fe3O4)+SO2→6Fe2O3+1/2S2. It is considered that the reactivity of Fe2O3 is attributable to the activity of (Fe3O4). The lifetime of active (Fe3O4) is within about 1 min, and the activity and lifetime of (Fe3O4) is increased by interfacial reaction between Fe2O3 and Al2O3 at 700 °C. The activity maximum in the Fe2O3–Al2O3 system preheated at 700 °C is attained at 70–75 wt% Fe2O3.
    研究了以机械混合方式制备的α-Fe2O3粉末(-200目)和α-Fe2O3–γ-Al2O3粉末混合物在360–700°C预热条件下对SO2与CO还原反应的催化活性,采用了反应气体色谱技术并结合CO、SO2和2CO–SO2脉冲及粉末X射线分析。结果表明,Fe2O3的活性随着预热温度的升高而降低,这可以通过Fe2O3与新生(Fe3O4)之间的氧化还原反应来解释:6Fe2O3+2CO→4(Fe3O4)+2CO2和4(Fe3O4)+SO2→6Fe2O3+1/2S2。认为Fe2O3的活性归因于(Fe3O4)的活性。活性(Fe3O4)的寿命约为1分钟,并且在700°C时通过Fe2O3与Al2O3之间的界面反应,(Fe3O4)的活性和寿命得以提升。在预热至700°C的Fe2O3–Al2O3体系中,活性达到最大值时Fe2O3的质量分数为70–75 wt%。
