| 摘要 |
<p>This invention relates to a process for reducing the carbonyl sulfide content of a gaseous stream which has a concentration of carbonyl sulfide of from at least 1 to about 100 parts per million, by volume, which comprises providing an adsorbent bed wherein the adsorbent comprises zinc oxide and contains no more than 5% by weight of an oxide of an alkali or alkaline earth metal, and contacting said process stream with said adsorbent bed at a temperature of from about ambient to 250°C for a period of time sufficient to remove at least 90% of the carbonyl sulfide content of said gaseous stream.</p> |
