Provided is a method for producing a high-purity aqueous lithium salt solution, the method allowing filtering aluminum phosphate in a short time. The method for producing a high-purity aqueous lithium salt solution includes: a step of adjusting the pH of a slurry containing a mixture of lithium phosphate and aluminum hydroxide obtained from a first aqueous lithium salt solution being a raw material to a range of 2 to 3 to obtain a precipitate of aluminum phosphate; a step of filtering off and removing the precipitate of aluminum phosphate to obtain a second aqueous lithium salt solution; and a step of purifying the second aqueous lithium salt solution to obtain a high-purity aqueous lithium salt solution.

A hydrogenation catalyst with a small amount of supported metal that is excellent in stability and inhibition of side reactions is provided. The catalyst hydrogenates an aromatic hydrocarbon compound into an alicyclic hydrocarbon compound, and a Group X metal represented by nickel is supported in a composite support including at least alumina and titania. The composite support preferably includes at least an alumina substrate coated with titania. It is also preferable that the Group X metal is prereduced by hydrogen. In the case that the Group X metal is nickel, the nickel content is preferably 5-35 wt % as nickel oxide in the catalyst. The substrate includes, for example, a porous structure formed by a plurality of needle-shaped or column-shaped intertwined three-dimensionally.
