Patent number: 11745164Abstract: A sorbent composition for enhanced baghouse function is described. The composition may include a sorbent such as powder activated carbon as well as an additive that is a heat moderator or a permeability agent. The heat moderator may act as a heat sink or barrier. Heat moderators may include in non-limiting examples phyllosilicates, cyclosilicates, or nesosilicates that may include, montmorillonite, bentonite, halloysite, aluminum silicates, muscovite, illite, kaolin, andalusite, kyanite, sillimanite, metakaolin, mullite, polymers, such as chitosan, and/or clays, either natural or synthetic (e.g., montmorillonite), or polyethylenimine. Permeability may be affected by mixing sorbents of lower D50 with sorbents of higher D50 in various ratios, or addition of a permeability agent such as a phyllosilicate, perlite, silica, diatomaceous earth. Further, a permeability agent such as a fluoropolymer may be coated onto or admixed with the sorbent.Type: GrantFiled: June 22, 2021Date of Patent: September 5, 2023Assignee: ADA Carbon Solutions, LLCInventors: Mowen Li, Robert B.

Patent number: 11491434Abstract: A sorbent composition for the sequestration of mercury from a gas stream, a method for sequestering mercury from a gas stream and a method for the manufacture of a sorbent composition. The sorbent composition includes a highly porous particulate sorbent and at least two additive components, namely a non-halogen metal compound comprising a metal cation and an inorganic sulfur-containing compound, where at least a portion of the sulfur in the sulfur-containing compound has an oxidation state of equal to or less than +4. The method includes injecting the highly porous particulate sorbent and the two additive components into a gas stream, either discretely or as a single sorbent composition, to sequester mercury in the particulate sorbent. The method has a high degree of efficacy for mercury removal without requiring the addition of halogens to the gas stream.Type: GrantFiled: May 21, 2019Date of Patent: November 8, 2022Assignee: ADA Carbon Solutions, LLCInventors: Roger H.
