Title: A process for the production of gasoline by catalytic pressure hydrogenation in a plurality of stages
IPC: F02B3/06
Filed: 1954-05-21
Abstract: In a multistage process for the destructive hydrogenation of heavy oils to obtain gasoline and diesel oils of the kind in which the topped crude is first subjected to hydrogenation in the liquid phase at 450-520 DEG C. under a pressure of at least 100 atmospheres and in presence of finely divided contact materials, the products are passed through at least two separators arranged in series and maintained at or near reaction temperatures and pressures, and the vapours from the last separator are further hydrogenated in a further reaction zone provided with a catalyst comprising a compound of a metal of Groups 5-8 on an acid carrier comprising an oxide of silicon or aluminium, solids including the contact material are withdrawn at the bottom of the first separator to an amount not exceeding 8 per cent while from 0.3 to 2 per cent asphalt, and resins are removed from the bottom of the second separator.  One of the separators may be kept at a temperature 50-150 DEG C lower than the first separator and a fuel oil removed therefrom.  After distilling off gasoline, and diesel oils the residual high boiling oil may be recirculated for further hydrogenation.  The gasoline obtained may be reformed at above 490 DEG C.; alternatively the high boiling oil may be subjected to catalytic cracking before being recycled.  (1) Emsland crude, topped to remove gasoline and middle oils boiling below 400 DEG C. and mixed with lignite coke containing 10 per cent iron sulphate, is passed through two reactors in series heated to 460 DEG C. under a pressure of 280 atmospheres; the products are passed through two separators the lignite coke paste being withdrawn from the first separator at 450 DEG C., while 30 kgs per hour of asphalt and resin are withdrawn from the bottom of the second separator; the vapours from the second separator are passed at 450-465 DEG C. and under a pressure of 270-275 atmospheres through two further reactors filled with shaped pieces of acid aluminium silicate impregnated with 8 per cent tungsten sulphide; the products are separated into gasoline of end point 200 DEG C., diesel oil of b.p. range 200-350 DEG C. and heavy oil 350-520 DEG C.  The latter together with middle oil from the topped crude is recycled to the vapour phase stage.  (2) the heavy oil produced is subjected to catalytic cracking to give a cracking tar which is mixed with the topped crude prior to the initial liquid phase hydrogenation (3) in this example while the temperature of the first separator is maintained at 460 DEG C. the temperature of the first separator is reduced to 405 DEG C. and heavy oil is withdrawn therefrom and recycled in part to the first stage; the catalyst in the vapourphase stage comprises alumina (pH=5.5) impregnated with 10 per cent MoO3.  The alumina is produced by precipitating an aluminium salt solution at 90 DEG C. with ammonia water, filtering the precipitate, washing and drying and then pasting with 3 per nitric acid, shaping in an extrusion press drying and calcining.

Title: Electric discharge rectifier system
IPC: H02M7/15
Filed: 1954-05-21
Abstract: 758,138. Rectifying; automatic speedcontrol systems. RELIANCE ELECTRIC & ENGINEERING CO. May 21, 1954 [June 1, 1953], No. 15041/54. Classes 38 (2) and 38 (4). A three-phase bridge-connected rectifying circuit supplying the armature of motor 13 from A.C. supply 27, comprises valves 21-26 having control grids each energized each cycle with two pulses phase displaced by 60 degrees, developed in phase splitting and pulsing circuits 55, 56, 57. These circuits are energized from phase-shift circuit 37 through an amplifier comprising push-pull connected valves 44, 45, and transformers 52, 53, 54. Circuit 37 is supplied from source 38 synchronously related to main source 27, and its output phase is controlled by speed-control circuit 36 and armature current and voltage feed-back circuit 34 connected through amplifier 35, the phase of all pulsing circuits being varied together. Phase-splitter circuits 55, 56 comprise capacitors 58, 62, linear reactors 59, 63 and trimming resistors 67, 68, while circuit 57 comprises two capacitors 64, 65 and linear reactor 66, the components being so chosen that the capacitors are charged at times differing by 120 degrees. The associated pulsing circuits comprise saturable reactors 71, 72, 73 which discharge the capacitors through the primary windings of transformers 81-92 connected in pairs in series with rectifiers 80. Pulses are developed in the secondary windings of these transformers which are so connected in parallel pairs between the valve cathodes and grids that each grid receives two pulses per cycle displaced by 60 degrees, the lagging pulse of one valve coinciding with the leading pulse of the next valve to fire, (see Fig. 3). The second pulse refires the valve when the general phase displacement is such as to cause discontinuous firing. Non-conduction of the valves during appropriate times is maintained by grid bias from sources 94, 95, 96, 97, resistances 100 shunting rectifiers 99 to dissipate the charge on condensers 98 which might override the bias. These rectifiers 99 reduce the negative peaks which, developed in the secondary windings of transformers 81-92 from the leading one of each positive pulse pair, tend to cancel the lagging one.

Filed: 1973-03-29
Abstract: 1396642 Borehole logging apparatus TEXACO DEVELOPMENT CORP 29 March 1973 15078/73 Heading G1A In a method for determining the unknown composition of earth formations surrounding a well borehole, standard gamma ray energy spectra of materials postulated to be in the formations surrounding a borehole are provided, gamma ray energy spectra of the unknown materials in the formation surrounding a borehole are obtained, each unknown gamma ray spectrum is compared with a composite standard spectrum comprising a weighted mixture of said standard spectra at a selected number of energy levels, and the characteristics of the composite spectrum are varied and the above composition is repeated in an iterative manner to achieve an optimized comparison. As shown, a sonde 5 contains a pulsed neutron source 11, e.g. a denterium-tritium accelerator and a gamma ray detector e.g. a sodium iodide or cesium iodide crystal 8 and a photo-multiplier 9. The output of the photo-multiplier is fed to an amplifier 13 and discriminator 14 whose output is applied to a gate 15 which is synchronized with the pulsed neutron source with an appropriate delay. The output of the gate 15 is applied to a driver 16 which supplies the signals to the surface via a cable 6. The signals pass to a pulse height analyzer 23 via a gate 40 synchronized with the gate 15. The analyzer 23 includes a plurality of channels whose outputs are applied to a comparison computer 42 which also receives the standard spectra from a source 30. These standard spectra are obtained using the same sonde in a borehole surrounded by formations of known composition. The results of the comparison are recorded at 46. The outputs of the pulse height analyzer 23 may be applied to a second recorder 27 for subsequent comparison at a later time.  Details of the computer program flow diagrams and the comparison operation are described with reference to, Figs. 2-5 (not shown). Basically, each unknown spectrum is compared with a weighted composite spectrum and this latter spectrum is altered and the comparison repeated in an iterative manner until the best fit has been found. The principle of least squares is used.
