Abstract: 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 H2S capacity in a range of from 140 cc H2S/g adsorbent to 250 cc H2S/g adsorbent, at normal conditions (1 atm, 293.15° K); (c) an H2S capacity in a range of from 1.0 cc H2S/g adsorbent to 15.0 cc H2S/g adsorbent, at partial pressure of 0.76 ton (101.3 Pa) (1000 ppm) of H2S 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 H2S-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.

Abstract: A polyvinylidene fluoride (PVDF) pyrolyzate adsorbent is described, having utility for storing gases in an adsorbed state, and from which adsorbed gas may be desorbed to supply same for use. The PVDF pyrolyzate adsorbent can be of monolithic unitary form, or in a bead, powder, film, particulate or other finely divided form. The adsorbent is particularly suited for storage and supply of fluorine-containing gases, such as fluorine gas, nitrogen trifluoride, carbo-fluoride gases, and the like. The adsorbent may be utilized in a gas storage and dispensing system, in which the adsorbent is contained in a supply vessel, from which sorbate gas can be selectively dispensed.
