The invention provides a process for treating waste water from an industrial process for producing propylene oxide, which process comprises subjecting the waste water to a catalytic wet oxidation treatment in the presence of a catalyst comprising metal nanoparticles-doped porous carbon beads.

A method for preparing a sol comprising TiO.sub.2 and ZrO.sub.2 and/or hydrated forms of TiO.sub.2 and ZrO.sub.2. The method includes mixing a material which includes metatitanic acid in an aqueous phase with a zirconyl compound or with a mixture of several zirconyl compounds. The material is provided either as a suspension or as a filter cake from the sulfate method. The material includes a H.sub.2SO.sub.4 content of 3 to 15 wt.-% relative to a quantity of TiO.sub.2 in the material. The zirconyl compound or the mixture of several zirconyl compounds is mixed in a quantity that is sufficient to provide the sol depending on the H.sub.2SO.sub.4 content.

The present invention discloses a novel transition metal(s) catalyst supported on nitrogen-doped mesoporous carbon and a process for the preparation of the same. Further, the present invention discloses use of transition metal(s) supported on nitrogen-doped mesoporous carbon catalyst in catalytic transfer hydrogenation reaction. The invention also discloses an improved process for the synthesis of 2,5-Dimethylfuran (DMF) and 2-Methylfuran (MF) from 5-hydroxymethylfurfural (HMF) and furfural respectively, using alcohols as hydrogen donor over a transition metal supported on nitrogen-doped mesoporous carbon, especially ruthenium supported on nitrogen-doped mesoporous carbon without using any co-catalysts.

The present invention provides titania particles which are formed by providing a titania sol and spray drying the titania sol. A morphology of the dried titania particles is controlled by producing the titania sol from a TiO.sub.2 containing slurry and controlling the pH of the slurry to be 3 pH units or more from the iso-electric point of the titania by adding a peptizing agent to reduce an extent to which the titania sol is flocculated, or by producing the titania sol from a TiO.sub.2 containing slurry and adjusting the iso-electric point to be 3 pH units or more from the pH of the slurry by adding a dispersant to reduce an extent to which the titania sol is flocculated. The titania particles have a continuous exterior convex surface, a diameter of 30 m or less, a BET specific surface area of 50 m.sup.2/g or more, and are porous.
