Compositions and methods for use in treating hydrocarbon liquids are provided. Specifically, the compositions and methods of the present disclosure relate to additives including betaine and one or more organic acids. In some embodiments, an additive comprising betaine and an organic acid may be added to a hydrocarbon liquid. In certain embodiments, the additive may be added to a hydrocarbon liquid prior to a processing operation.

A method of producing advanced carbon materials can include providing coal to a processing facility, beneficiating the coal to remove impurities from the coal, processing the beneficiated coal to produce a pitch, and treating the pitch to produce an advanced carbon material such as carbon fibers, carbon nanotubes, graphene, resins, polymers, biomaterials, or other carbon materials.

A method of making a composition of matter is provided. The method includes pH-modifying, that is, deacidifying, neutralizing or basifying, one or more water-soluble oxidized disulfide oil (WS-ODSO) compounds or mixture of compounds. The WS-ODSO is combined with an effective amount of an alkaline agent. The process results in a pH-modified, that is, deacidified, neutralized or basified, WS-ODSO composition, for example which can be used as a component in synthesis of materials such as zeolitic material.
