摘要：

Hydrocarbon impurities such as methane are removed from a gaseous air or oxygen stream by temperature swing adsorption. The stream is passed through a bed of adsorbent which is at a temperature of 150K or less. The adsorbent is selected so as to be able to adsorb selectively hydrocarbon impurities in preference to oxygen. A product stream essentially free of hydrocarbon impurities is produced. If the gaseous stream is oxygen it may be produced by fractional distillation of air and the adsorbent preferably also selectively adsorbs nitrogen in preference to air. If the gaseous stream is air, an oxygen product essentially free of hydrocarbon impurities is produced by fractional distillation of the purified air.

摘要（中）：

烃类杂质如甲烷通过变温吸附从气态空气或氧气流中除去。 将该物流通过150K以下的吸附剂床。 选择吸附剂以便能够优先选择性地吸附烃杂质。 产生基本上不含烃杂质的产物流。 如果气流是氧气，则可以通过空气的分馏产生，并且吸附剂优选也优选选择性地优先选择性吸附氮气。 如果气流是空气，则通过纯化空气的分馏产生基本上不含烃杂质的氧产物。
