Title: Catalyst manufacture
IPC: B01J23/882
Filed: 1957-09-09
Abstract: A nickel or cobalt and molybdenum, vanadium or tungsten impregnated activated alumina catalyst suitable for hydrodesulphurization of petroleum hydrocarbons is prepared by spray drying an aqueous slurry of alumina hydrate to obtain microspherical particles, preferably of 20-125 microns, containing up to 20% by weight free water and 10-90% alumina trihydrate, impregnating with an aqueous solution of catalytic promotors selected from Ni, Co and Mo, Va or W to, at least, a 50% free water content, drying with heated gases to 5-20% free water content, reconstituting to 30-50% free water content, extruding the mixture to obtain particles from 1/16 inch to 1/2 inch in diameter and 1/16 inch to 1 inch in length, drying below 400 DEG F. to less than 5% free water content and calcining above 750 DEG  F. to give a porous catalyst with a pore volume of, at least, 0.3 c.c./gm.  Impregnation of the spray dried alumina hydrate may be effected by (i) absorbing water-soluble compounds of the catalytically active metals on the spraydried alumina base or (ii) precipitating the active materials from water-soluble acid salts of the promoting metals and an aqueous slurry of the alumina base or preferably (iii) absorbing water-insoluble compounds of the metals, for example, oxides, carbonates, basic carbonates or sulphides, from an aqueous mixture of the compounds and the alumina hydrate.  The total active metal components estimated as the metal oxides can comprise from 1-40 weight per cent of the catalyst.  The alumina hydrate can contain minor amounts of other materials, such as, silica and may be prepared, for example, from aluminium chloride or other acidic aluminium salts and aqueous ammonium hydroxide to give amorphous alumina hydrate which converts to the trihydrate on removal of the electrolytes by washing.  Alternatively, alumina monohydrate or amorphous forms can be blended with alumina trihydrate.  Examples given describe the preparation of the activated catalyst impregnated with molybdic oxide and cobalt carbonate and use of the catalyst to desulphurize oil at 580-780 DEG  F. in the presence of hydrogen. Molybdic oxide can be substituted by tungstic acid or vanadium pentoxide and cobalt carbonate can be replaced by nickel carbonate.

Abstract: 1,147,210. Vitamin beadlets. EASTMAN KODAK CO. 24 June, 1966 [30 June, 1965], No. 28352/66. Heading A5B. A process for making a dry, free flowing, finely divided, fat-soluble vitamin-active product, comprises (1) preparing a colloidal solution of cold water dispersible, non-gelling colloid material and water; (2) dispersing in said colloidal solution a water insoluble, fat soluble vitamin active composition to form a first dispersion; (3) dispersing the latter in a water immiscible liquid dispersing medium to form a second dispersion; (4) extracting water at - 10 to 0‹C from the latter with a water extraction agent until droplets of the first dispersion solidify to form particles; (5) separating the latter from the dispersing medium and water extraction agent at -10 to 0‹C; and (6) removing residual moisture from the solid particles. Lecithin may be added as a stabilising agent to the second dispersion. The colloid material may be gum acacia, gum ghatti, amylopectin, pre-gelatinised and thin boiling starches, substituted starches, e.g. corn starch which has 'been partially reacted with octenyl succinic anhydride, or mixtures thereof. Water soluble, edible, plasticizers e.g. glucose, sucrose, dextrose, lactose, and corn syrup may 'be used with the colloid material. The vitamin-active composition consists of at least one water insoluble, fat soluble, vitamin active compound e.g. vitamin A, D, E, and K compounds. The compounds may be in solution or suspended in oil. The vitamin active composition may 'be liquid, solid, or a mixture of solids and liquid. An antioxidant may be incorporated in the vitamin active composition. The water immiscible dispersing medium may be mineral oil. Specified water extracting agents are methanol, ethanol, isopropanol, acetone, methyl ethyl ketone, 1,4-dioxan, pyridine, and mixtures thereof. The particles may be separated from the dispersing medium by filtration and washed with additional water extraction agent and then with a solvent for the dispersing medium e.g. hexane when the medium is mineral oil. Residual moisture may be removed by air drying, for instance, using a fluidised bed.

Abstract: 1,020,946. Phosphorous-doped silicon device. WESTINGHOUSE ELECTRIC CORPORATION. July 9, 1964 [July 24, 1963], No. 28382/64. Heading H1K. A semi-conductor junction device is made by forming a darkened layer on a surface of a silicon semi-conductor wafer or on selected portions thereof and diffusing phosphorus through the darkened layer. In a specific embodiment a silicon body 10 doped with B, A1, Ga, or In is lapped or cleaned by an etchant e.g. a mixture of HF, HNO 3 and CH 3 CO a H or hot NaOH solution and then partially masked with a wax or photo-resist material. The exposed portion of the body 10 is electrolytically darkened 14, the masking material removed and the body subjected to phosphorus diffusion to give a diffused layer 16, of phosphorus which is deeper under the darkened layer. The surface layer of N-type material 16 on the side and bottom of the body 10 may be removed and a groove formed on the upper layer to give two separate N-type regions. In other embodiments (Figs. 9 and 12, not shown) a three junction device and a field effect transistor having a gate region of gradually varying depth are made. The masking material may be left in place while the electrolytic darkening takes place. Alternatively, no mask may be applied but rather only a portion of the semi-conductor body contacted with the electrolytic bath e.g. in the case of the field effect transistor, the body is slowly withdrawn thus giving a darkening to different extents. Starting materials of resistivity less than 10 ohm. cm. are preferably whilst in the case of materials of resistivity greater than 1 ohm cm. illumination whilst darkening is advantageous. A current density of less than 100 ma. cm.<SP>-1</SP> is preferable. The electrolytic darkening bath may be conc. HF with or without glycerine or ethylene glycol. The phosphorus diffusion may be carried out using elemented phosphorus in a closed tube, P 2 O 5  in an open tube gas flow system or a solution of P 2 O 5 in ethylene glycol.
