Classes 55 (1) and 55 (2). Combustible gases are produced from normally-liquid hydrocarbons, e.g. a reduced crude oil, still bottoms or a residual oil, having a viscosity of not less than 45 S.S.U. and preferably not less than 160 S.S.U. at 210‹ F. by contacting them with a fluidized bed of finely divided coke-covered particles in a coking zone at a temperature between 1830-2200‹ F. The bed may be fluidized by means of C 1  to C 3  gaseous hydrocarbons, hydrogen, steam or carbon monoxide and the fluidizing gas may be preheated. The temperature of the coking zone may be maintained by circulating some of the coke-covered particles to and from a separate heating zone maintained by partial combustion at 100-500‹ F. and preferably 200-400‹ F. above the temperature of the coking zone. The process may be operated at pressures between 0 and 50 p.s.i.g. and the feed-stock preheated to 600-700‹ F. In starting up the process the operating temperature in the coking zone may be obtained by partial combustion in the zone using pure oxygen. Specifications 791,755 and 791,756 are referred to.

Title: Improvements in sewage purification plant and apparatus connected therewith
IPC: C02F1/00
Filed: 1921-12-28
Abstract: 192,561. Adams, S. H. Dec. 28, 1921. Aerating; plant.-Automatic dosing tanks, preferably siphonic, are used for supplying sewage to activated-sludge aerating-tanks and for agitating or otherwise aerating the liquid therein. In the apparatus shown in Fig. 2, a siphon e in a dosing-tank d delivers liquid through a chamber f, pipe l and nozzle m into an aerating-tank o. The contents of the tank o are thereby caused to circulate through a funnel-shaped pipe n arranged over the nozzle m. Liquid passes from the tank o under a scum-board o<1> and over a sill o<2> into a chamber t. Discharge of the chamber t through a pipe q is controlled by a siphon air-lock j, which is connected by a pipe h to a dome g in the chamber f, air being released from the lock when liquid has been drained from the chamber f through a pipe k. Sludge can be discharged from the tank o to the chamber t through a valved pipe r. In a modified form of this apparatus, the pipe n is omitted and a plurality of smaller nozzles take the place of the central nozzle m. In the form of apparatus shown in Fig. 4, the pipe l delivers the liquid into the head v of a rotary distributor having perforated arms y. The shaft of the distributor is continued downwards and provided with stirring arms z. Fig. 6 shows the application of a dosing. tank 1 with siphon 2 to a long rectangular aerating tank 4, 5. The main supply pipe 3, into which the siphon discharges, has perforated branches 6 - - 11, arranged near the floor of the tank so that the jets therefrom promote the flow of the liquid through the tank and lift the sludge into the current. A sludge basin 16 is formed at the end of the tank and the sludge is withdrawn therefrom through a pipe 12 to a chamber 14 when liquid is discharged from the chamber 14 by a siphon 15. Reference is made to the use of travelling distributors for delivering liquid to rectangular aerating-tanks and to the use of the power of a distributor for operating a pump to lift sludge from a settling tank. It is also stated that the pressure of air within a dome may be used to agitate sludge or to force sludge at intervals from a setting-tank to the aerating- tanks.

Filed: 1928-11-26
Abstract: 301,329. Durand & Huguenin Akt.- Ges. Nov. 26, 1927, [Convention date]. Gallocyanines. - Gallocyanines derived from meta-substituted alkylanilines, and having the general formula where R, = alkyl, R2 = hydrogen or alkyl, R3 = OH, NH2, NH-aryl, or O-alkyl, and X a substituent, e.g. CH3 or halogen, are converted into derivatives in the usual manner; these derivatives, which retain the group X, show increased stability towards hydrosulphite, as compared with the corresponding unsubstituted products, and are suitable for use in discharge printing. In examples, (1) the gallocyanine from nitrosodiethyl-m-toluidine and gallamide is converted into the anilido compound by treating with aniline in presence of dinitrobenzene and alcohol, according to Specification 15138/07, and the product is sulphonated by heating with oleum; the resulting dye yields greenish-blue tints in chrome-printing on cotton, and is more stable in discharge printing than the corresponding dye from nitrosodiethylaniline and gallamide, (2) the gallocyanine from nitrasodiethyl-m-chlonaniline and gallamide is similarly treated, (3) gallamide is heated with nitrosadimethyl-m-chloraniline hydrochloride and methyl alcohol, and the gallocyanine obtained is converted into the anilido derivative and sulphonated; the product gives more reddish tints in -chrome -printing on cotton than the product of example 1, (4) nitrosomonoethyl-m-toluidine hydrochloride is heated with gallaimide and methyl alcohol, and the resulting gallocyanine is converted into the anilido derivative and sulphonated; the product shows a very marked increase in stability in discharge printing as compared with the isomeric dye from nitrosomonoethyl-o-toluidine : in the foregoing examples another arylamine, e.g. a toluidine, chloraniline or naphthylamine may be substituted for aniline, (5) gallic acid is treated with nitrosomet-hyl-mtoluidine in methyl alcohol and the product is converted into the corresponding gallocyanine or its leuco derivative derived from pyrogallol by elimination of the carboxylic group by the process of Specification 9961/07; the resulting dye yields violet tints in discharge printing, whereas the corresponding dye from nitrosodimethylaniline is useless for this purpose since it undergoes decomposition, and (6) the gallocyanine from nitrosodimethyl-m-toluidine and gallamide is heated with diethyl-p-phenylenediamine and dinitrobenzene and the product is reduced to the leuco compound by the process described in Specification 21949/06; it agrees in dyeing properties with the leuco compound of the product obtained according to example 1 of the latter Specification, but is more stable in discharge printing. Nitrosomonoethyl-m-toluidine is made by the action of nitrous acid on monoethyl-mtoluidine and isomeric change of the nitrosoamine thus obtained.

Abstract: 860,549. Electrolytic production of potassium permanganate. CARUS CHEMICAL CO. Nov. 8, 1957 [Jan. 9, 1957], No. 34917/57. Class 41. A process for electrolytically oxidizing potassium manganate to potassium permanganate comprises passing an aqueous potassium hydroxide solution of potassium manganate through a closed electrolytic cell in regulated flow co-currently with the flow of gases produced. The process involves mixing the aqueous potassium hydroxide solution of potassium manganate with product solution, electrolytically oxidizing the resulting solution and crystallizing the resulting solution to produce crystals of potassium permanganate and the aforesaid product solution. As shown (Fig. 1), the aqueous potassium hydroxide solution of potassium manganate is prepared in tank 1 to which fresh potassium manganate is added together with recovered and recycled potassium manganate and mother liquor from the process containing potassium hydroxide, potassium manganate and potassium permanganate. The solution is pumped by pump 2 from tank 1 through filter 3 to tank 4 where it is further diluted with mother liquor and heated with steam. Thence it passes through pump 6 to electrolytic cell 7 wherein the potassium manganate is electrolytically oxidized to potassium permanganate. The solution from cell 7 passes to gas separator 8 thence to riser 9 wherein it is pumped up to vaporizer 11 together with liquor from crystallizer 5. The cooled solution in the vaporizer, supersaturated with potassium permanganate, descends into crystallizer 5 wherein crystals are formed which are withdrawn in a slurry by pump 13 and then washed with water in centrifuge 14. The cell 7 (Fig. 2) is composed of a bank or column of dipolar electrodes 15 in side-by-side relationship and secured together to form a plurality of individual cells which are grouped into three cell sections 16a, 16b and 16c. The feed solution passes through cells in each cell section in series and the three cell sections are fed in parallel. The cell design and flow pattern provide cocurrent flow of liquid and gases. The operating conditions for the cell are regulated basically according to the production of oxygen in the cell which is determined by analysis of the effluent gases. A curve is first plotted of the anode efficiency versus the oxygen content for the cathode efficiency at which the cell will be operated. The cell is maintained in operation at the optimum anode efficiency by adjusting the potassium manganate feed rate on the current density according to the production of oxygen. Specifications 860,548 and 860,550 are referred to.
