    • 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。
