Abstract: The process of producing spray-dried granules useful as detergents, cleaning compositions, or as a component therefor, by preparing a slurry containing 0.2% to 20% by weight of sugar acids or salts thereof and the balance being detergent components, wherein the slurry contains less than 35% by weight of water and has a viscosity of less than 15,000 mPas under spray-drying conditions, and spray-drying the slurry.

Abstract: Free-flowing granulates having an apparent density of 650 to 1,000 g/l and containing nonionic surfactants from the class of polyglycol ether derivatives and also finely divided, water-soluble and/or water-insoluble solids and water are prepared by mixing the nonionic surfactant with water, which may optionally contain part, but less than 50% by weight, of the total quantity of water-soluble or water-insoluble solids in dissolved or dispersed form, in a first mixing step (A) until a viscous gel phase has formed. The remaining main quantity of the water-soluble or water-insoluble solids are then added and mixed in solid, powder form in a second mixing phase (B) and the mixture is mechanically treated until granulates have formed and a maximum apparent density is reached. The ratio by weight of nonionic surfactant and water in the gel phase to total solids present (expressed as anhydrous substance) is from 25:75 to 65:35. Zeolites and bentonites are particularly suitable as the water-insoluble solids.

Abstract: The invention concerns a process for the continuation granulation of a mixture containing at least one solid material and at least one liquid exhibiting a tendency to gel formation. In order to make it possible to work with a gel-like intermediate phase and yet continue to granulate, it is proposed that a mixture containing liquid raw materials which, by themselves, do not show any tendency to gel be used as the liquid exhibiting a tendency to gel, this mixture being produced in a static mixer, its average dwell time in the mixer being shorter than the gel time. The liquid is subsequently allowed to gel in a stirrer vessel, the dwell time in the stirrer vessel being longer than the gel time. Only then is the highly viscous mass thus obtained granulated together with the solid material.

Abstract: A granular mixture produced by spray drying of(a) 45 to 75% by weight zeolite,(b) 1 to 6% by weight of a water soluble soap of substantially saturated C.sub.12-18 fatty acids,(c) 1 to 12% by weight homopolymers or copolymers of acrylic acid, methacrylic acid or maleic acid or water-soluble salts thereof, expressed as sodium salt,(d) 0 to 25% by weight sodium sulfate,(e) 0 to 5% by weight surfactants of the nonionic polyglycol ether derivative type,(f) 10 to 22% by weight water,has an average particle size of 0.2 to 1.2 mm and an apparent density of 350 to 680 g/l. The product, which may be used as a detergent additive, has a high adsorption capacity for liquid to paste-form detergent constituents, more particularly nonionic surfactants, and improved flushing behavior when used in domestic washing machines.

Abstract: To produce granular, free-flowing detergents containing sodium metasilicate, pentasodium triphosphate or zeolite NaA or a triphosphate/zeolite mixture, at least two of the components are first agglomerated and mixed as a granular preagglomertate with other components present in powder form and compacted by means of rolls, the pressure limit beyond which no further compaction is obtained not being significantly exceeded. The compactate is then size-reduced to the desired particle size.

Abstract: Stabilized aqueous zeolite A suspensions containing a nonionic surfactant as a stabilizer and an anionic surfactant as a stabilizer auxiliary are improved by using at least one sulfated C.sub.10-20 alcohol or substituted alcohol as the stabilizer auxiliary. In a further embodiment, an acid salt may be added to the suspension to adjust the pH to below 12.

Abstract: A process for oligomerizing olefins having 2 to 5 carbon atoms in the molecule employing a novel sulfur containing molybdenum supported catalyst composed of from about 5.0 to 11.0 weight percent molybdenum, 3.0 to 7.0 weight percent sulfur and the remainder support. The catalyst may have present additional members such as platinum, palladium, rhodium, ruthenium, cobalt, nickel, rhenium and tungsten.

Abstract: A process for oligomerizing unsaturated hydrocarbons having 2 to 5 carbon atoms in the molecule employing a novel molybdenum-containing carrier catalyst.

Abstract: Supported olefin conversion catalysts are activated by a method which comprises calcining the catalyst, impregnating the calcined catalyst with an alcoholic solution of an alkali metal salt, an alkali metal base or an alkali metal alcoholate and then recalcining the catalyst.
