Title: Improvements in and relating to the catalytic cracking of hydrocarbon oils
IPC: C10G11/04
Filed: 1939-02-21
Abstract: 525,443. Catalytic conversion of hydrocarbons. STANDARD OIL DEVELOPMENT CO. Feb. 21, 1939, No. 5750. Convention date, May 18, 1938. [Class 32] In the catalytic conversion of hydrocarbon oils solid catalyst is brought into contact with the oil and recovered therefrom by injecting it in suspension in a stream of carrier gas into a reaction zone in counter current to the oil vapours, withdrawing the mixed vapours and catalyst, condensing the products, separating the catalyst from the condensate, regenerating it and returning it to the reaction. Crude oil is vaporized in a pipe heater 2 and the vapours with or without passage through a separator 5 are injected into a reactor 3 through a spray 38 in countercurrent to a jet of finely-divided catalyst suspended in a carrier gas fed through line 37. The reaction products are withdrawn through line 6 to a condenser 7 where sufficient vapours are condensed to form a slurry of oil and catalyst which is separated from the residual vapours and gases in separator 8. Alternatively, condensation may be obtained by injection of a cooling oil. The cooling is regulated (a) to condense all the vapours in which case the condensate is separated from catalyst in a rotary filter 13 of conventional construction and the separated condensate is redistilled in heater 17 and tower 11 to recover the gasoline which is condensed in cooler 28 and separated from gases in separator 29. In this case gases only are recovered through line 9 ; (b) by cooling to about 400‹ F. in the cooler 7 so as to condense fractions heavier than gasoline, the gasoline vapours being then recovered through line 9 and further fractionated in tower 11. Fractions of higher boiling range condensed in tower 11 are recycled through line 15a. The catalyst separated in the filter 13 is freed from oil in a vessel 19, e.g., by steam distillation. the vapours thus recovered being passed to the still 17 while the catalyst is passed to a regenerator 22 where carbonaceous deposits are removed by oxidation, e.g., as described in U.S.A. Specification 1,475,502. The regenerated catalyst after passage through a steaming chamber 23 is recycled to the storage bin 24. The gases removed from the separator 32 are preferably separated from hydrogen and methane by treatment with an absorber oil in a vessel 42 followed by redistillation from the oil in a still 45 and are then blown bv a fan 35 through a line 36 so as to form a suspension of the catalyst fed from the bin 24 by a conveyer 25.

IPC: B03B13/00
Filed: 1955-03-01
Abstract: 799,579. Washing granular materials. SIMON - CARVES, Ltd. Feb. 21, 1956 [March 1, 1955], No. 6007/55. Class 82(2) In a process for separating coal into constituents of different specific gravities, the coal is first subjected to a separation according to specific gravity in a trough or jig washer or other apparatus employing water for treating the coal; and is subsequently subjected to a separation according to specific gravity in a dense medium washer, a part of the clays removed in the first wet treatment being subsequently added to the dense medium separator in order to stabilize the medium. In Fig. 1, raw coal (e.g. up to 6 inches in size) is supplied at 1 to a jig washer box 2, to which water from a settling tank 4 is supplied via a pipe 3. After being washed in box 2 the coal passes to a draining screen 5, the liquid draining therefrom passing to a tank 6, the coal passing to a classifying screen 7 where small material (up to ¢ inch) is removed, the larger material being conveyed to a sink and float separator 8 supplied with dense medium of the correct density from a stock tank 11. Liquid collected in tank 6 is pumped to the settling tank 4, solid material accumulating at the bottom of tank 4 is removed from time to time, drained on a screen 10 and disposed of, the liquid draining to tank 6. Part of the clay-containing liquid in the settling tank 4 is led to the separator 8. Alternatively, this liquid may be conveyed, possibly through a thickener such as a cyclone 16, to the medium stock tank 11 to be mixed with the medium before it is pumped to the separator 8. Fig. 2 shows a medium recovery system. The sinks from separator 8 are sprayed with wash water on screen 27; the first part of the underflow is returned to the stock tank 11 and the second part to a dilute medium tank 24. The coal is washed by water on screen 30, the first part of the underflow being returned to the stock tank 11 and the second to the dilute medium tank 24. The medium is then pumped to a magnetic separator 35 where slimes, clay and water overflow and pass to tank 36, to be re-used as wash water. The medium from the bottom of tank 35 is pumped through a demagnetizer 37 to a splitter box 40 from which part of the medium is led to the stock tank 11 and the remainder to the magnetic separator 35. Some of the overflow from tank 36 may be taken to a cyclone 43 to be thickened and led to tank 11, the water from the cyclone returning to the wash water circuit. Alternatively, the slimes and clay may be taken for thickening to a cyclone 48 and then led to stock tank 11, the water being returned to tank 24. Specification 728,195 is referred to.

Patent GB-397848-A (GB)
Title: Improvements in and relating to the storage of fruit
IPC: A23B7/148
Filed: 1932-02-29
Abstract: 397,848. Storing and preserving crops ; hatching-appliances ; treating grain. KIDD, F., Low Temperature Research Station, Downing Street, Cambridge. Feb. 29, 1932, No. 6059. [Classes 5 (i), 5 (ii), and 58.] Animal and vegetable materials, including fertile eggs, potatoes and other roots, bulbs and seeds are preserved during storage and transport by controlling the composition of the atmosphere surrounding the materials by treating it with physical or chemical absorbents for carbon dioxide of a reversible character so that regeneration may be conveniently effected, and then returning the treated gas to the chamber with, if desired, a proportion of fresh air. The absorbents for carbon dioxide used include sea or river water, potassium or sodium carbonate solutions or other inorganic or organic solvents. Where a solid absorbent is employed, a plurality of absorption chambers may be used which are employed alternately in absorbing the gas and in treating the absorbent to expel the gas therefrom. The oxygen content of the gas may be reduced, e.g. by burning carbon or carbon-containing material therein. The regeneration of the absorbent may be effected by aeration, by reduction of pressure, by change in temperature, e.g. by heating with waste heat from the refrigerating plant, by increasing the surface of the absorbent liquid while being treated with heat, cold or vacuum or passage of air &c., or by finely subdividing the liquid and passing it in contact with a gas, or by employing catalysts. To promote absorption the absorbent may be cooled by means of the brine or other cooling medium used for keeping the storage chamber at the desired low temperature. Means may be provided to absorb volatile substances given off by the materials under storage, e.g. by placing absorbents in the storage chamber or by providing chambers containing absorbents in the path of the circulating gas. As shown, gas containing carbon dioxide is withdrawn from a fruit storage chamber 1 by a pump 3 through a trunk 2 and a pipe 4 and passes to a pipe 7, one branch of which is connected through a valve 8 to a spray eliminator 9 through which a regulated part of the gas is byepassed to the chamber 1. The remainder of the gas passes through the other branch of pipe 7 and a valve 10 to a chamber 11, where the carbon dioxide is absorbed by a descending solution of sodium or other alkali metal carbonate or other appropriate liquid. The treated gas passes through pipe 16 and valve 17 to the spray eliminator 9 and back through pipe 19 and a cooler 20 having a cooling coil 21 to the chamber 1. A controlled amount of air may be added to the returning gas through a valve 24. The used absorbent liquid is delivered from chamber 11 by a pump 28 through a pipe 30 to the top of a chamber 31, where it is revivified by a current of air supplied through a pipe 34 and distributor 35 and leaving the chamber by a pipe 36. The treated liquid returns to chamber 11 through a pipe 14.
