Abstract:
Methods of preparing a mercury sorbent material are provided. The methods comprise making a copper/clay mixture by admixing a dry clay and a dry copper source; making a sulfur/clay mixture by admixing a dry clay and a dry sulfur source; admixing the copper/clay mixture and the sulfur/clay mixture, to form a mercury sorbent pre-mixture; and shearing the mercury sorbent pre-mixture to form the mercury sorbent material. Various substrates may be used with or instead of the clay, and various additives may be added to the copper, sulfur, clay, or mixture thereof.

Claim (Index 19):
A mercury sorbent material comprising a material that comprises\n a first clay, a second clay, or a combination of a first clay and a second clay; a dry copper source; and a first sulfur source, a second sulfur source, or a combination of a first and a second sulfur source; wherein at least one member of the group of conditions (a), (b), and (c) applies;\n condition (a) the mercury sorbent also comprises an additive and the additive comprises a dispersant, an oxygen scavenger, a moisture scavenger, an intercalation reagent, or any combination thereof; \n condition (b) the second clay is present and comprises talc, chloritic talc, chlorite clay, atapulgite, sepiolite clay, imogolite clay, halloysite clay, perlite, lignite, bleaching earth clay, or a combination thereof; \n condition (c) the second sulfur source is present and comprises elemental sulfur, sodium trithiocarbonate, silane with thiol functionality, sodium dimethyl-dithiocarbamate, one or more sodium salts of trimecapto-s-triazine, or a combination thereof; \n and wherein mercury sorbent material is substantially free of a clay/covellite composite as determined by powder X-ray diffraction, the powder X-ray diffraction pattern being substantially free of a peak at 2.73\u00b10.1 \u212b.
