Title: Process for the preparation of oxidation catalysts
IPC: B01J23/85
Filed: 1965-11-16
Abstract: Iron molybdate is prepared by (a) adding an aqueous solution of a salt of iron having a pH 0.8 to 1.5 to an aqueous solution of a salt having an anion containing Mo; (b) separating and crushing the precipitate which forms; (c) drying the precipitate to a water content of 55 to 62%; (d) kneading the precipitate; (e) drying the kneaded precipitate to a water content of 0.5 to 1.5% by weight by progressively heating the precipitate initially at 70 DEG  F. and rising to at most 325 DEG F. over 5 to 7 days; (f) comminuting the precipitate from (e) and separating material of 3 to 12 mesh particle size from the remainder; and (g) calcining the separated material at 600 DEG  to 900 DEG  F. for 24 to 72 hours to produce a substantially anhydrous FeMoO4. The method of preparation is stated to be of use in preparing iron and/or cobalt tungstates and/or molybdates.ALSO:Aldehydes are obtained by oxidation of alcohols in the presence of an iron and/or cobalt molybdate and/or tungstate catalyst which has been prepared by a multi-stage process.  In an example, air containing 8.5-9.5 vol. per cent of methanol was passed over such a catalyst at 570-560 DEG  F. to yield 91-94% H.CHO.  Ethyl and higher alcohols may likewise be oxidized but no details are given.ALSO:Oxidation catalysts are made by (a) adding an aqueous solution of Fe and/or Co having a pH of 0.8 to 1.5 to an aqueous solution of a salt having an anion containing Mo and/or W, (b) separating and washing the resulting precipitate, (c) drying the precipitate to a water content of 55 to 62% by weight, (d) kneading the precipitate, (e) drying the kneaded precipitate to a water content of 0.5 to 1.5% by progressively heating the precipitate initially at 70 DEG F. and rising to at most 325 DEG F. over 5 to 7 days (f) comminuting the precipitate from (e) and separating 3-12 mesh particle size from the remainder, and (g) calcining the separated material at 600-900 DEG F for 24 to 72 hours to produce a substantially anhydrous catalyst.  Mixed oxide catalysts may be made containing effectively FeO, CoO, MoO3 and WO3. The catalyst may be supported on carborundum.

Title: Method of making npk fertilisers

Filed: 1971-10-25
Abstract: 1420305 Mixing solids and liquids in flow ALBRIGHT & WILSON LTD 25 Oct 1972 [25 Oct 1971] 49547/71 Heading B1C [Also in Division Cl]  In a method of mixing together particulate potassium chloride and liquid nitrogen-phosphorus melt to form an N:P:K fertiliser, the liquid melt is formed into a continuous, funnelshaped vortex having a vertical axis and a stream of the particulate potassium chloride is 'dropped along the axis and deflected outwardly into the vortex. In one apparatus for carrying out the method Fig. 1, the liquid is introduced tangentially into chamber 1 through inlets 4 so as to form the vortex. The stream of solid particles is fed down inlet 5 and is deflected by a static or vibrated conical deflector 7 which may be vertically adjustable by means of rod 8. A skirt 9 may be used to protect the deflector from liquid splashes. The mixture passes out through outlet 3. In another apparatus the conical deflector is replaced by a rotating impeller plate (10 Fig. 2 not shown) which displaces the particles centrifugally, while in a further apparatus, Fig. 3, there is an electrostatic conductor 13 electrically insulated from the chamber 1-which along with skirt is earthed-the conductor on being charged by means 7, providing a corona discharge which charges and repels the particles. A vertically adjustable deflector 16 forms the particles into a curtain around the conductor 13. The apparatus including the funnel and inlets may be steam-jacketed to keep the mixture sufficiently fluid. In a particular example, a 93-95% solution of ammonium nitrate was mixed with cold phosphoric acid containing 49-53% P 2 O 5  to produce a final product with the ratio N:P 2 O 5  equal to 1:1. This was treated with ammonia gas in a neutralizer at boiling point and atmospheric pressure to the equivalent of pH 2.7-3.0 in a 10% aqueous solution. Concentrated sulphuric acid was added and the NP solution was evaporated at 0.1-0.15 atmospheres absolute pressure to form a melt containing 0.3-1.0% water. The pH was then raised with ammonia. The hot melt was passed to the apparatus shown in Fig. 1 where preheated potassium chloride was added. The mixture was passed directly to a spinning, perforated prill bucket at the top of a prilling tower. Hot prills were recovered by raking from the floor of the tower. The product had a N:P 2 O 5 :K 2 O ratio of 15:15:21.

A method of manufacturing a heat exchanger matrix comprises assembling a stack of copper wire gauzes and depositing alternate layers of wax and a hardenable material such as epoxy resin (or water glass) transverse to the stack gauzes, the wax layers 8 being ultimately removed by heating so that fluid ducts through the exchanger matrix for heat exchanging fluids are defined by walls formed by the hardenable material. As shown, in order to form the matrix the exchanger stack 1 is placed within a temporary envelope 2 having end faces 3 and 4. Liquid wax is introduced and the stack plus envelope assembly is rotated about its longitudinal axis, first with the axis vertical and then with the axis turned horizontally. This is said to ensure uniform distribution of the liquid wax. After solidification of the wax liquid epoxy resin or water glass is introduced and a layer 9 is similarly deposited by centrifugal action. Additional layers 8 and 9 may be formed by repeating the procedure. The stack is then removed from the envelope and heated to melt out the wax so defining a plurality of concentric tubular ducts separated by walls constituted by the layers 9. The exchanger matrix so formed may be mounted in a cylindrical housing (10, Fig. 2, not shown) provided with suitable inlets and outlets for the heat-exchange media. In an alternative arrangement (Figs. 3-5, not shown) comprising a quadrangular stack (31) of gauze 5 contained within a temporary envelope (32) serving as a mould, alternate horizontal layers of wax and epoxy resin are deposited and the wax subsequently removed to define parallel ducts; the stack may then be turned through 90 degrees and the method repeated forming an exchange matrix with ducts of square or rectangular cross-section.
