A method of this disclosure for removing oxygenates from a hydrocarbon process stream includes passing the hydrocarbon process stream through a vessel containing a mixed metal oxide having an amorphous non-crystalline structure and containing a metal in at least two oxidation states in a hydrate form, the hydrocarbon process stream having a first oxygenate content when entering the vessel and a second lower oxygenate content when exiting the vessel. The hydrocarbon stream may be a gas or a liquid stream.

Method for reducing the oxygenate content of a hydrocarbon process stream treated with or containing an oxygenate

The various embodiments of the invention relates to the composition of a hydrogen sulfide capture material and the related method of manufacture. The hydrogen sulfide capture material is formed by solubilizing an iron source in acid to form an aqueous solution comprising iron chloride, neutralizing the aqueous solution with a caustic solution to form a neutralized solution, washing the neutralized solution to separate it into water and a slurry, forming a thickened slurry by removing additional water from the slurry, separating the thickened slurry to produce filtered water and a wet filter cake, and drying the wet filter cake to form granules. The hydrogen sulfide capture material of the present invention removes hydrogen sulfide for a longer time and at a faster rate than the materials of the prior art, thereby improving the efficiency and decreasing the cost of sour gas treatment.
