摘要：A process for separating by pressure swing adsorption a gas mixture comprising a first component which is adsorbed in preference to the other component or
components of the mixture (for example a mixture of methane and oxygen which contains methane at a concentration greater then the upper explosive gas mixture limit is
separated without producing an explosive gas mixture) includes the steps of feeding the gas mixture into an adsorber which contains an adsorbent which preferentially adsorbs methane until the desired production pressure is attained in the adsorber and then stopping the flow of feed gas into the adsorber and charging methane product gas at the production pressure cocurrently into the adsorber while simultaneously withdrawing nonadsorbed product gas from the nonadsorbed product end of the adsorber. The desorbed product stream is enriched in methane relative to the feed stream and the concentration of methane in the nonadsorbed product stream is less than the minimum flammable mixture concentration.
