Title: Process for the recovery of benzene from petroleum oils or crude residues
IPC: C10G47/12
Filed: 1951-05-22
Abstract: In producing benzine from petroleum oils or crude residues containing not more than 2 per cent. of asphalt and at least 12 per cent. of hydrogen, the raw material is passed with hydrogen or hydrogen containing gas at 400-550 DEG C. and a pressure greater than 200 atmospheres with a throughput of 0.3-1.5 kgms. of oil per litre of catalyst per hour, over rigid catalysts consisting of natural or synthetic silicates, silica gel or alumina carrier to which has been added a small amount of molybdenum and/or tungsten compounds, and preferably an additional and smaller amount of a chromium nickel, cobalt or iron compound, and the conditions of temperature, pressure and rate of flow for a given catalyst are correlated so that the reaction product of a once-through operation with a gas formation of less than 6 per cent. by weight contains 35-65 per cent. benzine. Components heavier, than benzine are recycled so that in all more than 80 per cent of the raw materials is converted to benzine or more than 90 per cent. to benzine and readily liquifiable hydrocarbon Suitable raw materials are Near East or German crude oils, or asphalt-containing oils poor in hydrogen which have been presaturated to increase the hydrogen content.  If desired some middle oil may be withdrawn from the reaction products before recycling of the heavier products.  Preferably not more than 35 per cent. of reaction mixture is in the liquid phase.  Volatile oil may be added to ensure this. In the example oil containing 20 per cent benzine, 36 per cent. middle oil and 44 per cent. residues is stripped of benzine and passed at 1 kgm./hour/litre of catalyst space over a filled catalyst at 500 atmos. and 460 DEG C. with 3 cubic metres of hydrogen/kgm of oil.  The catalyst was fullers earth which had been pretreated with HF, pilled, soaked with ammonium molybdate and heated at 400-450 DEG C.  It contained 5 per cent. molybdenum oxide.  The product was 40 per cent. benzine and 60 per cent. higher boiling products which were recycled. Total yield was 89 per cent. benzine 9 per cent. readily liquifiable gaseous hydrocarbon on front of the catalyst chamber, a chamber may be arranged with Raschig rings of alumina or with the same catalyst.  This increases the life of the catalyst.

Abstract: 575,132. Hydraulic shock-absorbers. NEWTON, E. P. (Monroe Auto Equipment Co.). July 22, 1943, No. 11963. [Class 108 (iii)] A hydraulic shockabsorber comprises two piston sections B, C spaced apart within a compression cylinder A and each containing. valve-controlled fluid passages, means for byepassing fluid through one of the sections to the space between the sections, and means responsive to the velocity of the fluid for controlling the flow through the byepassing means. As shown, the piston sections B, C are carried by the reduced lower end 10 of the piston-rod D which contains a slot 50 in open communication with an annular channel 49 in a sleeve E arranged between the sections, and orifices 51 extending radially from the channel 49 register normally with orifices 52 in a slide F on the sleeve balanced by springs 60, 61. The piston section B is mounted between washers 11, 12 and the section C between a washer 15 and a nut 16 and the sections each contain two series of ports 13, 14 and 17, 18 respectively. The washers 11, 15 are for smaller diameter than the cylinder to provide clearance passages 20, 22 for flow of fluid and each has a circular series of holes 21 and 23 through which fluid may flow from the inner series of piston ports 13 and 17. Resilient disc valves M, N are provided, each having a curved slot 25 and 34 registering with the inner series of ports 13, 17 and an imperforate outer section spring-pressed to close the outer series of ports 14, 18, flow of fluid through the inner series of ports 13, 17 being controlled by leafspring valves 30, 40 respectively. In operation, during slow compression of the shock-absorber, fluid passes through the slot 50, orifices 51, 52, ports 14 and past the valve M which provides some resistance. On faster compression, the flow of fluid from the orifices 52 causes the slide F to move upwardly and partly or wholly close the orifices 51 when fluid is forced through the ports 18 against the resistance of the valve N. On fast extension of the shock-absorber, the slide moves downwardly and fluid is forced through the ports 17 past the valve 40. A valve assembly H controls flow of fluid between the lower end of the cylinder and the reserve chamber J.
