摘要:
Methods of producing solid CO2 sequestering carbonate materials are provided. Aspects of the methods include introducing a divalent cation source into a flowing aqueous liquid (e.g., a bicarbonate rich product containing liquid) under conditions sufficient such that a non-slurry solid phase CO2 sequestering carbonate material is produced. Also provided are systems configured for carrying out the methods.

An example method of removing hydrogen sulfide from an input gas includes exposing an adsorbent material to an input gas to obtain an output gas. A concentration of hydrogen sulfide of the output gas is less than a concentration of hydrogen sulfide of the input gas. The adsorbent material includes copper oxide, magnesium oxide, and aluminum oxide. An atomic ratio of copper to magnesium to aluminum of the adsorbent material is X:Y:Z, where X is greater than or equal to 0.6 and less than or equal to 0.9, where Y is greater than or equal to 0 and less than or equal to 0.2, where Z is greater than or equal to 0 and less than or equal to 0.2, and where X + Y + Z is equal to 1.

摘要:
The herein disclosed technology provides a method of producing a carbon dioxide-absorbing material that exhibits improved CO 2 absorption characteristics. This production method is a method of producing a carbon dioxide-absorbing material in which a major component thereof is lithium silicate, and includes the following steps: preparing a sol composition in which an Li-Si precursor compound containing a lithium (Li) component and a silicon (Si) component is dispersed in an aqueous solution; obtaining a gel composition by exposing the sol composition to electromagnetic waves; and calcining the gel composition to obtain a lithium silicate containing lithium and silicon. As for a carbon dioxide-absorbing material, at least a part of a surface of the lithium silicate may be covered with a alkali carbonate. At least a part of the surface of this lithium silicate may be covered by an alkali carbonate.

摘要:
The disclosure relates to copper oxide-based sorbents, and processes for preparing and using them. The sorbents are preferably used to remove one or more sulfur species from gas streams. The sorbents comprise a porous silica support material impregnated with CuO nanoparticles. The nanoparticles are uniformly distributed throughout the porous silica support and sulfur compounds are adsorbed on the nanoparticles.
