Abstract
1501571 Purifying O 2 -containing malodorant gas CALGON CORP 15 April 1976 [22 April 1975] 15641/76 Heading CIA [Also in Division B1] Sulphur containing compounds (viz. H 2 S, mercaptans and organic sulphides R-S-R<SP>1</SP> where R and R' is each a C 1-5 alkyl group and the total number of C atoms in R and R' is not greater than 8) are removed from gas streams containing O 2 by contacting the gas stream with an activated C impregnated with 0À5 to 20 wt. per cent NaOH and 4-50 wt. per cent moisture (i.e., essentially pure H 2 O held within the activated C by adsorption), the activating being used as adsorbent for the S- containing compounds. As an additional step, NaOH may be used to regenerate the activated C which has become saturated with H 2 S and the other malodorous S-containing compounds. NaOH treatment may be undertaken by soaking the unused or loaded activated C in its own volume of an aqueous NaOH solution of from 5 to 60% by wt. concentration; the C may be in granular form, e.g., between 4 and 10 U.S. sieve size, and have pore diameters 10 to 80 . Typically, O 2 is present in the gas stream in amounts at least 5 vol. per cent: the O 2 normally being derived from air.
