Abstract
A system and method for the treating at least one undesirable constituent in an aqueous mixture utilizing a particulate solids catalyst. The aqueous mixture and the particulate solids catalyst form a slurry which is wet oxidized.
Claims30
A catalytic wet oxidation process, comprising:
- providing an aqueous mixture containing at least one undesirable constituent to be treated;
- contacting the aqueous mixture with a particulate solids catalyst to form a slurry mixture comprising the at least one undesirable constituent to be treated and the particulate solids catalyst;
- treating the slurry mixture at a subcritical temperature and a superatmospheric pressure to oxidize the at least one undesirable constituent and form an oxidized slurry mixture;
- and
- separating at least a portion of the particulate solids catalyst from the oxidized slurry mixture.

The process of 1, wherein contacting the aqueous mixture with a particulate solids catalyst comprises contacting the aqueous mixture with an aqueous slurry of the particulate solids catalyst.
A catalytic wet oxidation system, comprising:
- a wet oxidation unit;
- a source of an aqueous mixture comprising at least one undesirable constituent fluidly connected to a feed inlet of the wet oxidation unit;
- an aqueous mixture conduit comprising:
- an inlet fluidly connected to an outlet of the source of the aqueous mixture;
- and
- an outlet fluidly connected to the feed inlet of the wet oxidation unit;
- a source of particulate solids catalyst, insoluble in the aqueous mixture, fluidly connected to at least one of a catalyst inlet of the wet oxidation unit, the source of the aqueous mixture, and the aqueous mixture conduit;
- and
- a separator comprising an inlet fluidly connected to an outlet of the wet oxidation unit and a catalyst slurry outlet fluidly connected to at least one of the catalyst inlet of the wet oxidation unit, the source of the aqueous mixture, and the aqueous mixture conduit.
