    摘要: By the present invention, a process is provided to use a modified clinoptilolite adsorbent suitable for the separation of carbon monoxide from hydrogen and hydrocarbon streams without adsorbing hydrocarbons such as paraffins and olefins. In typical applications in platforming units within refineries, these hydrogen streams contain from 5 to 20 parts per million of carbon monoxide. In other applications the level of carbon monoxide may be higher. The separation of carbon monoxide from the hydrogen stream is achieved by using a clinoptilolite molecular sieve that has been ion-exchanged with at least one cation selected from lithium, sodium, potassium, calcium, barium, and magnesium.

    摘要: The present invention relates to a process for the separation of ethanol from a mixture thereof with ethyl tert.-alkyl ether employing a selective adsorbent comprising a mixture of sodium zeolite Y in combination with alumina wherein the percentage of the sodium zeolite Y ranges between 10 and 40 wt-%. The invention reduces the cost of this separation which is complicated by an azeotrope formation between the alcohol and the ether.
