    • A durable carbon pyrolyzate adsorbent having reversible sorptive affinity for hydrogen sulfide, and including the following characteristics: (a) a bulk density as measured by ASTM D2854 in a range of from 0.55 g/cc adsorbent to 1.25 g/cc adsorbent; (b) an H 2 S capacity in a range of from 140 cc H 2 S/g adsorbent to 250 cc H 2 S/g adsorbent, at normal conditions (1 atm, 293.15°K); (c) an H 2 S capacity in a range of from 1.0 cc H 2 S/g adsorbent to 15.0 cc H 2 S/g adsorbent, at partial pressure of 0.76 torr (101.3 Pa) (1000ppm) of H 2 S at 293.15°K; and (d) a single pellet radial crush strength in a range of from 7 kilopond (kP) to 40 kilopond (kP) as measured by ASTM D4179. Such adsorbent is usefully employed for capture of hydrogen sulfide from gases containing same, such as H 2 S-containing gas associated with flowable hydrocarbonaceous material in refining operations, biogas produced by biomass digesters, gas mixtures produced by fluid catalytic cracking (FCC) units, and effluents from power plants gasifying sulfur-containing coal in an integrated gasification combined cycle (IGCC) process.
    • 具有对硫化氢具有可逆吸附亲和力的耐久碳热解物吸附剂,并且包括以下特征:(a)通过ASTM D2854测量的在0.55g / cc吸附剂至1.25g / cc吸附剂范围内的堆积密度; (b)在正常条件(1大气压,293.15°K)下,在140cc H2S / g吸附剂至250cc H2S / g吸附剂的范围内的H2S容量; (c)在293.15°K的分压为0.76乇(101.3Pa)(1000ppm)的H 2 S下,在1.0cc H 2 S / g吸附剂至15.0cc H 2 S / g吸附剂的范围内的H 2 S容量; 和(d)通过ASTM D4179测量的单个颗粒径向压实强度在7千帕(kP)至40千碱基(kP)的范围内。 这种吸附剂有用地用于从含有其的气体中捕获硫化氢,例如在精炼操作中与可流动的烃类材料相关的含H 2 S的气体,由生物质消化器产生的沼气,由流化催化裂化(FCC)单元产生的气体混合物,以及流出物 来自发电厂在一体化气化联合循环(IGCC)过程中气化含硫煤。

    • An article comprising a non-conductive substrate having a sub-micron thickness of an oxidizable metal coating thereon, and at least one feature selected from the group consisting of: (i) an oxidation enhancingly effective amount of a salt, present on the oxidizable metal coating; (ii) a second (promoter) metal which is galvanically effective to promote the corrosion of the oxidizable metal coating, discontinuously coated on the oxidizable metal coating; (iii) the oxidizable metal coating being sulfurized; and (iv) the oxidizable metal coating being overcoated with a microporous layer of an electrically insulative material. Also disclosed are related methods of forming such articles, comprising chemical vapor depositing the oxidizable metal coating on the substrate. When utilized in a form comprising fine-diameter substrate elements such as glass or ceramic filaments, the resulting product may be usefully employed as an "evanescent" chaff. In the presence of atmospheric moisture, such evanescent chaff undergoes oxidization of the oxidizable metal coating, so that the radar signature of the chaff transiently decays.
    • 一种制品,其包含其上具有亚微米厚度的可氧化金属涂层的非导电基材,以及选自以下的至少一种特征:(i)氧化增强有效量的存在于可氧化金属上的盐 涂层; (ii)第二(促进剂)金属,其电流上有效地促进可氧化金属涂层的腐蚀,不连续地涂覆在可氧化金属涂层上; (iii)可氧化金属涂层被硫化; 和(iv)用可电绝缘材料的微孔层涂覆可氧化的金属涂层。 还公开了形成这种制品的相关方法,包括在基材上化学气相沉积可氧化金属涂层。 当以包括诸如玻璃或陶瓷细丝的细直径基底元件的形式使用时,所得产物可有效地用作“ev逝”谷物。 在存在大气水分的情况下,这种消逝的小麦经历可氧化金属涂层的氧化,使得谷壳的雷达标记瞬时衰变。
