摘要
An adsorption process is disclosed for removal of carbonyl sulfide (COS) from a liquid hydrocarbon which comprises providing an activated alumina adsorbent which has preferably impregnated with a compound selected from the class consisting of one or more alkali metal compounds, one or more alkaline earth metal compounds, or a mixture of such compounds; passing a liquid hydrocarbon containing COS through the activated alumina adsorbent at a flow rate sufficient to adsorb enough COS in the liquid hydrocarbon to lower the COS content of the liquid hydrocarbon to less than 1 ppm; monitoring the effluent liquid hydrocarbon to determine when the capacity of the adsorbent to adsorb the COS has been reached; and then regenerating the activated alumina adsorbent by passing a gas, heated to a temperature of from about 150. degree. to about 300° C., through the adsorbent for a period of time sufficient to remove a substantial amount of the sulfur adsorbed thereon.
