    摘要： A method for the separation of a gas mixture comprises (a) obtaining a feed gas mixture comprising nitrogen and at least one hydrocarbon having two to six carbon atoms; (b) introducing the feed gas mixture at a temperature of about 60° F. to about 105° F. into an adsorbent bed containing adsorbent material which selectively adsorbs the hydrocarbon, and withdrawing from the adsorbent bed an effluent gas enriched in nitrogen; (c) discontinuing the flow of the feed gas mixture into the adsorbent bed and depressurizing the adsorbent bed by withdrawing depressurization gas therefrom; (d) purging the adsorbent bed by introducing a purge gas into the bed and withdrawing therefrom an effluent gas comprising the hydrocarbon, wherein the purge gas contains nitrogen at a concentration higher than that of the nitrogen in the feed gas mixture; (e) pressurizing the adsorbent bed by introducing pressurization gas into the bed; and (f) repeating (b) through (e) in a cyclic manner.

    摘要： Method for the separation of a gas mixture comprising providing a PSA system with at least one adsorber vessel containing adsorbent material that is selective for the adsorption of carbon monoxide and nitrogen, passing a feed gas mixture containing at least hydrogen and carbon monoxide and optionally containing nitrogen through the adsorbent material in a feed step and withdrawing a purified hydrogen product from the adsorber vessel, wherein the feed step has a duration or feed time period of about 30 seconds or less. The adsorbent material is characterized by any of (1) a Henry's law constant for carbon monoxide between about 2.5 and about 5.5 (mmole/g)/atm; (2) a carbon monoxide heat of adsorption between about 6.0 and about 7.5 kcal/gmole; (3) a Henry's law constant for nitrogen greater than about 1.5 (mmole/g)/atm; and (4) a selectivity of carbon monoxide to nitrogen between about 5.0 and about 8.0.
