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 1):
A method of manufacturing a mercury sorbent material comprising:\n adding mercury sorbent components, optionally made into a pre-mixture, to a shearing apparatus, the mercury sorbent components comprising:\n a first dry clay, a second dry clay, or a combination of a first dry clay and a second dry clay; \n a dry copper source; and \n a first dry sulfur source, a second dry sulfur source, or a combination of a first and a second dry sulfur source; \n 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 dry 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 dry 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 forming the mercury sorbent material by shearing the mercury sorbent components using the shearing apparatus; wherein a powder X-ray diffraction pattern of the mercury sorbent material is substantially free of a diffraction peak at 2.73\u00b10.01 \u212b.
