| 摘要 |
<p>The present invention provides for a process for purifying carbon monoxide-containing gas streams that contain impurities such as hydrocarbons by using a cryogenic adsorption process. Preferably this process is a temperature swing adsorption process at cryogenic temperatures below -750C. Alternatively, the carbon monoxide-containing gas streams may be purified using the cryogenic adsorption process with membrane separation units or vacuum swing adsorption units or cryogenic distillation.</p> |
