Title: Improvements in or relating to catalyst for the hydroforming of hydrocarbons and process employing said catalyst
IPC: C10G35/09
Filed: 1954-08-31
Abstract: A platinum or alumina hydroforming catalyst is prepared by impregnating solid hydrous alumina containing 1-30 per cent by weight, based on dry Al2O3, of combined water with a solution of a platinum compound in the presence of 0.001-0.02 mole of a water-soluble inorganic aluminium salt per mole of dry Al2O3, the amount of platinum added is 0.01-1 per cent by weight, based on dry Al2O3.  The alumina may be formed by drying and/or calcining an alumina gel or sol; alumina gel may be prepared by precipitating an aluminium salt solution with alkali and washing and drying, and alumina sol by hydrolysis of aluminium alkoxide or by the method described in Specification 552,053.  The alumina may be treated simultaneously or successively with a solution of the aluminium salt and the solution of the platinum compound; alternatively finely divided alumina may be dry mixed with a finely divided aluminium salt and the mixture impregnated with the solution of the platinum compound.  Suitable aluminium salts are the chloride, bromide, iodide, nitrate, and sulphate.  Platinum compounds specified are chloroplatinic acid, bromoplatinic acid, platinum tetrachloride, and platinum dichloride.  When a solution of an aluminium salt is used, it may have a concentration of 0.01-0.3 M and may contain an organic solvent, e.g. acetone, methanol, ethanol, or isopropyl alcohol, or a wetting agent, e.g. sodium benzenesulphonate, a polyethylene glycol, or a glycol ether.  A preferred range of temperatures for treatment with the aluminium salt solution is 50 DEG -200 DEG F.  The alumina impregnated with aluminium salt may be shaped, e.g. into pellets, before or after addition of the platinum.  The final catalyst may be dried at 200 DEG -300 DEG F. for 1-24 hours, calcined at 800 DEG -1200 DEG F. for 1-24 hours, and treated with hydrogen at 850 DEG -1000 DEG F.  In examples, alumina hydrosol prepared by reacting amalgamated aluminium with hot 2 per cent acetic acid is dried, calcined, crushed, formed into pellets, again calcined, and then impregnated with solutions containing chloroplatinic acid and aluminium chloride, nitrate, or bromide.  The catalysts have a higher hydroforming activity and a greater crushing strength, compared with catalysts prepared without the addition of aluminium salts.  Carbon deposited on the catalyst during use may be removed by treatment with oxygen at a maximum temperature of 830 DEG F., followed by soaking in oxygen at 1100 DEG F. and a pressure of 1 atmosphere.

Title: Improvements in means for regulating piston type variable delivery pumps
IPC: F04B49/24
Filed: 1944-02-15
Abstract: 592,618. Fluid-pressure servomotorcontrol systems. PRECISION DEVELOPMENTS CO., Ltd., ROSSZ, L., and OLAH, G. Feb. 15, 1944, No. 2816. [Class 135] In a variable delivery radial-cylinder reciprocating pump, the pistons are actuated by an eccentric 2, the throw of which is varied by pistons 8 and 12 that engage it. The piston 12 is forced out of its cylinder 13 by a spring 11 or fluid pressure or, as shown in Fig. 3, a combination of both, to maintain the stroke of the pistons at a maximum. A valve 14 is maintained against the stop 18a by a spring 15 and is acted upon by the pump delivery pressure in port 16, which is also transmitted through the port 17 to the piston 12. When the pump delivery pressure is below normal, the cylinder 9 is connected to the exhaust ports 20, through a passage 18, and around the reduced portion 14a of the valve. As the delivery pressure rises, the valve first closes the exhaust connection and then admits pressure fluid to the piston 8 to move the eccentric to reduce the pump stroke. If the delivery pressure still increases, the groove 14c in the-valve-moves to connect the pump delivery to exhaust; a further relief valve may also be fitted. Fig. 4 shows a modified valve in which initial movement first closes port 18 leading to the piston 8 and disconnects it from the exhaust port 20 and further, movement opens port 18 to receive pressure fluid from the port 16, until finally, the port 16 is connected to the exhaust 20. A throttle passage 23 may be fitted between the valve and exhaust or between the pump delivery and the piston 8. The loading of the valve 14 may be effected by two springs acting through a toggle.
