Abstract

This disclosure provides a halogenated activated carbon composition comprising carbon, a halogenated compound and a salt. In some embodiments, the halogenated compound and the salt comprise a naturally occurring salt mixture, as may be obtained from ocean water, salt lake water, rock salt, salt brine wells, for example. In some embodiments, the naturally occurring salt mixture comprises Dead Sea salt.

First claim

What is claimed is:

1. A biogenic activated carbon composition comprising:
80 wt % or more total carbon;
10 wt % or less hydrogen;
a first salt comprising a halogenated compound selected from the group consisting of copper bromide, copper chloride, and combinations thereof; and
a second salt;
wherein the halogenated compound and the second salt are present in a total amount of about 0.2 wt % to about 20 wt %, and wherein the second salt is optionally halogenated;
wherein the first salt and/or the second salt are from a naturally occurring salt mixture;
wherein the naturally occurring salt mixture is from a source selected from the group consisting of ocean water, salt lake water, rock salt, salt brine wells, and combinations thereof; and
wherein the naturally occurring salt mixture comprises Dead Sea salt.

2. A biogenic activated carbon composition comprising:
80 wt % or more total carbon;
10 wt % or less hydrogen;
a first salt comprising a halogenated compound selected from the group consisting of copper bromide, copper chloride, and combinations thereof; and
a second salt;
wherein the halogenated compound and the second salt are present in a total amount of about 0.2 wt % to about 20 wt %, and wherein the second salt is optionally halogenated;
wherein the first salt and/or the second salt are from a naturally occurring salt mixture;
wherein the naturally occurring salt mixture is from a source selected from the group consisting of ocean water, salt lake water, rock salt, salt brine wells, and combinations thereof; and
wherein the naturally occurring salt mixture comprises Dead Sea salt and Great Salt Lake salt.

3. A biogenic activated carbon composition comprising:
80 wt % or more total carbon;
10 wt % or less hydrogen;
a first salt comprising a halogenated compound selected from the group consisting of copper bromide, copper chloride, and combinations thereof; and
a second salt;
wherein the halogenated compound and the second salt are present in a total amount of about 0.2 wt % to about 20 wt %, and wherein the second salt is optionally halogenated;
wherein the first salt and/or the second salt are from a naturally occurring salt mixture;
wherein the naturally occurring salt mixture is from a source selected from the group consisting of ocean water, salt lake water, rock salt, salt brine wells, and combinations thereof; and
wherein the naturally occurring salt mixture is a mixture of Dead Sea salt and sea salt from ocean water.

4. An activated carbon product comprising biogenic activated carbon and Dead Sea salt.

5. The activated carbon product of claim 4 , wherein the activated carbon product consists essentially of biogenic activated carbon and Dead Sea salt.

6. The activated carbon product of claim 4 further comprising Great Salt Lake salt.
