Filed:

Oct 17, 2022

Appl. No.:

17/967462

Inventors:

- Littleton CO, US
Mowen Li - Highlands Ranch CO, US
Micala D. Mitchek - Arvada CO, US
Lingyan Song - Englewood CO, US

International Classification:

B01D 53/02
B01D 53/64

Abstract:

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.

Abstract:

A sorbent composition for the removal of boron and/or borates from a fluid such as an aqueous medium. The sorbent composition includes a base sorbent material having a high porosity and surface area, and a boron-selective agent. By using a boron-selective agent in conjunction with a high surface area base sorbent material such as activated carbon or biochar, a sorbent composition with a high capacity for sequestering boron and a relatively low cost is provided. The sorbent compositions are particularly useful for the sequestration of boron from waste materials such as coal combustion residual leachate (CCRs).

International Classification:

C09K 13/02
C09K 13/00

Abstract:

Compositions useful for the selective removal of titanium nitride and/or photoresist etch residue materials relative to metal conducting, e.g., cobalt, ruthenium and copper, and insulating materials from a microelectronic device having same thereon. The removal compositions contain at least one oxidant and one etchant, may contain various corrosion inhibitors to ensure selectivity.
