Abstract: The invention relates to a photocatalyst containing titanium dioxide, to a method for using it and to its application. A sulphurous titanium dioxide hydrate precipitate is precipitated from an acid titanium oxysulphate solution at a temperature below the boiling point of the solution, e.g. in the range from 70 to 100° C., using crystal nuclei and without addition of base. The precipitate is separated, washed and calcinated. The photocatalytic titanium dioxide thus obtained has a specific area in the range from 100 to 250 m2/g and a 0.3 to 5% sulphur concentration. Catalytic activity has been confirmed in asetal dehyde decomposition and in anionic (SNC−)2 radical formation.

Abstract: Self-heating characteristics of a spontaneously combustible catalyst are reduced by treating spontaneously combustible catalysts with oxygen-containing hydrocarbons having at least 12 carbon atoms. The treatment is particularly suitable for reducing the self-heating characteristics of sulfidable metal oxide(s)-containing catalysts, presulfurized catalysts, presulfided catalysts or reduced catalysts. When applied to sulfur-containing catalysts, the treatment gives a catalyst that has suppressed self-heating properties without substantially compromising sulfur retention or activity. Further, a method of safely unloading a catalyst from a reactor is provided where the catalyst in the reactor is treated with a liquid mixture containing oxygen-containing hydrocarbon having at least 12 carbon atoms to wet the catalyst.

Abstract: A dispersed fine-sized anion-modified iron oxide slurry catalyst having high surface area exceeding about 100 m.sup.2 /gm and high catalytic activity, and which is useful for hydrogenation and hydroconversion reactions for carbonaceous feed materials is disclosed. The catalyst is synthesized by rapid aqueous precipitation from saturated salt solutions such as ferric alum or ferric sulfate, and is promoted with at least one active metal such as cobalt, molybdenum, nickel, tungsten and combinations thereof. The iron-based dispersed catalysts are modified during their preparation with anionic modifiers such as molybdate (MoO.sub.4.sup.2-), phosphate (PO.sub.4.sup.3-), sulfate (SO.sub.4.sup.2-), or tungstate (WO.sub.4.sup.2-). The resulting catalyst usually has primary particle size smaller than about 50 Angstrom units, and may be used in the form of a gel or wet cake which can be easily mixed with a hydrocarbonaceous feed material such as coal, heavy petroleum fractions, mixed waste plastics or mixtures thereof. Alternatively, the catalyst can be dried and/or calcined so as to be in a fine dry particulate form suitable for adding to the feed material. The invention includes methods for making the catalyst and processes for using the catalyst for hydroprocessing of the carbonaceous feed materials.
