Abstract
An adsorbent product for the adsorption of trace elements of sulfur, arsenic, mercury, compounds which contain these elements or metal hydrides from a hydrocarbon gas stream, preferably an olefinic or paraffinic stream, wherein the adsorbent product is iron oxide and manganese oxide placed on a support material, preferably aluminum oxide. Also disclosed is a process for the use of this adsorbent product for the removal of trace elements of arsenic, mercury and sulfur or compounds containing those elements or metal hydrides from a hydrocarbon gas stream, preferably an olefinic or paraffinic gas stream.
Claims18
An adsorbent for the removal of trace impurities of mercury, arsenic, metal hydrides, chlorides or compounds containing those impurities from a hydrocarbon stream comprising iron oxide, manganese oxide, and a support material, wherein the percentage by weight of the iron oxide and the manganese oxide in the adsorbent product is at least about 50 percent, wherein the percentage of manganese oxide is from about 20 to about 30 percent by weight and wherein the ratio of the iron oxide to the manganese oxide by weight is between about 3 to 1 and about 1 to 3.
An adsorbent product for the removal of trace impurities of mercury, arsenic, metal hydrides, chlorides or compounds containing those impurities from a hydrocarbon stream comprising about 40 to about 65 percent iron, oxide;
- about 20 to about 30 percent manganese oxide and from about 10 to about 20 percent of a support material.
