Abstract: Compositions and methods for controlled delivery of acid to a desired location, for instance to a subterranean formation, are disclosed. A method for in situ acid stimulation of a subterranean formation that contains a hydrocarbon reservoir and a method for in situ acid treatment of a subterranean formation includes contacting the subterranean formation with (a) a sulfonate-based ammonium salt capable of being oxidized to produce acid; and (b) an oxidizing agent capable of oxidizing the sulfonate-based ammonium salt, where the ammonium salt and oxidizing agent in the aqueous fluid react to produce acid. The method for in situ acid stimulation of a subterranean formation includes stimulating the subterranean formation with the produced acid. The method for in situ acid treatment of a subterranean formation includes treating the subterranean formation with the produced acid.

Abstract: In some embodiments, the present disclosure pertains to materials for use in CO2 capture in high pressure environments. In some embodiments, the materials include a porous carbon material containing a plurality of pores for use in a high pressure environment. Additional embodiments pertain to methods of utilizing the materials of the present disclosure to capture CO2 from various environments. In some embodiments, the materials of the present disclosure selectively capture CO2 over hydrocarbon species in the environment.

Abstract: In some embodiments, the present disclosure pertains to methods of capturing a gas from an environment by associating the environment (e.g., a pressurized environment) with a porous carbon material that comprises a plurality of pores and a plurality of nucleophilic moieties. In some embodiments, the associating results in sorption of gas components (e.g., CO2 or H2S) to the porous carbon materials. In some embodiments, the methods of the present disclosure also include a step of releasing captured gas components from porous carbon materials. In some embodiments, the releasing occurs without any heating steps by decreasing environmental pressure. In some embodiments, the methods of the present disclosure also include a step of disposing released gas components and reusing porous carbon materials. Additional embodiments of the present disclosure pertain to porous carbon materials that are used for gas capture.
