Patent GB-364215-A (GB)
Title: Improved method of and apparatus for carrying out catalytic gas reactions
IPC: B01J8/04
Filed: 1930-10-18
Abstract: <PICT:0364215/III/1> In carrying out catalytic gas reactions at an elevated temperature, the reactants are separately preheated by heat exchange with different portions of the reaction products, the extent to which each reactant is preheated being independently controlled by regulating the amount of reaction product with which it contacts, preferably by means of a valve on the cold side of the heat exchanger.  If one reactant is more sensitive to heat than the other, the amount of preheating may be regulated to avoid decomposition, while the insensitive reactant may be preheated to as near the reaction temperature as desired, or it may be preheated to a temperature above that of the reaction, thus making good any deficit of heat due to the partial preheating of the other reactant.  The process is applicable to the catalytic hydrogenation of organic compounds, such as naturally occurring oils or conversion products thereof, or conversion products of carbonaceous solids in general. In the production of low-boiling hydrocarbons by the catalytic hydrogenation of middle oil (boiling at 200-300 DEG  C.) obtained by the destructive hydrogenation of coal, the oil is injected into the pipe 1, and vaporized in the heat exchanger 2, being preheated to about 400 DEG  C. above which temperature decomposition occurs, the vapours passing into the chamber 4.  Hydrogen, or a gas mixture containing it, is preheated to about 450 DEG  C. by passage through the exchanger 6 and further heated to 550 DEG  C. by the heater 8, and then mixes with the oil vapours in the chamber 4.  The gas mixture passes down through the catalyst beds 11, 12, 13 maintained at about 470 DEG  C., means being provided to add cold hydrogen if an excessive temperature rise occurs, and finally the gaseous products leave by the pipe 19, and are divided at point 20 into two streams passing through the heat-exchangers 2, 6 respectively, the relative amounts of gases passing through each exchanger being regulated by valves 22, 23. Specification 349,238 is referred to.

Patent GB-673165-A (GB)
Title: Improvements in the production of combustible gases containing methane from finely divided fuel
IPC: C10J3/46
Filed: 1949-12-07
Abstract: 673,165. Gasifying powdered fuel. KOPPERS CO., Inc. Dec. 7, 1949 [Dec. 7, 1948], No. 31421/49. Classes 55 (i) and 55 (ii). A combustible gas containing methane is produced by forming a suspension in oxygen under pressure of a finely-divided solid fuel such as coal or lignite, injecting the suspension in the form of a jet into an internally heated chamber where the fuel ignites and is partly burnt, introducing steam under pressure into the space between the jet and the walls of the chamber, the steam reacting with the combustion gases and unburnt fuel from the jet to give a gas containing carbon monoxide and hydrogen and finally bringing this gas under increased pressure into contact with low temperature coke which acts as a catalyst to cause conversion of some of the CO and H 2  into methane. The gasifying step in this process is the same as that described in Specification 673,164, but the other process omits the methane synthesis. In the form shown, the apparatus consists of a reaction chamber 8, a catalyst shaft 21, a dust extractor 29 and a washer 31, each unit being constructed to withstand high pressures. Finely divided solid fuel (10-25 per cent on a 4900 meshes per sq. cm. sieve) is charged into bins 1 and 2 and fed to a mixer 5 by conveyers 3 and 4. Oxygen or oxygen enriched air enters the mixer through a pipe 6 to form a suspension with the fuel, the suspension passing through a pipe 7 into the smaller end of the conical gasification or reaction chamber 8. Surrounding the pipe 7 is an annular jet through which steam, under the same pressure, enters the chambers, the steam being superheated to 400-600‹ C. by combustion of gas from burners 15. The fuel is partially burnt in the oxygen in a jet-like primary zone 12, a flowing envelope of steam surrounding this zone and serving to protect the chamber walls from its high temperature, and preventing the deposition thereon of fused ash. The gases and remaining fuel from zone 12 react with the steam lower in chamber 8 to form a gas consisting mainly of CO and H 2'  which leaves the chamber at about 1200‹ C. It is cooled to about 800‹ C. by admission of cold gas at 16 and by passing into a chamber surrounded by a water jacket 17 connected with a steam boiler, the solid fuel residues depositing at 18 for periodic removal through valve device 19, whilst the gas passes through a duct 20 to shaft 21. This shaft is fed with low temperature coke through which the gas passes upwardly, the coke acting catalytically to cause methane formation by part combination of the CO and H 2  constituents. The gases then pass through the dust extractor 29 and washer 31 to outlet 32. Operating with pressures of 8-10 atmospheres, a gas with 8-12 per cent methane is obtained, whilst 40 atmospheres gives a gas containing 40 per cent methane.

Abstract: 1402875 Digital balance DR JOHANNES HEIDENHAIN 6 July 1972 (6 July 1971] 31807/72 Heading H3H A digital balance connected to a reversible counter 41, a store 42 and a printer 43, incorporates a counterweight changeover device 15 for extending the range NL-HL of the scale to upper and lower overrun ranges L, H; the output of the device 15 (which represents the total weight of the counter-weights in use) is reduced by a positive integer n in a decimal to binary converter 71 before being fed to an adder 72 controlling the highest decade of the store, the adder being controlled by a logic circuit 80 to add n + 1, n or n-1 to the reduced weight according as the balance scale is in the range L, NL-HL, or H respectively. A grating scale 11 and tracks 19-21 on the balance 22 are scanned by photo-cells and grating tracks 17, Fig. 3 (not shown), to provide phase-displaced signals T<SP>1</SP>, T<SP>11</SP> and signals G, S and O. T<SP>1</SP> and T<SP>11</SP> are fed via a direction discriminator 40 to the add/subtract inputs V, R of counter 42, and pulse O resets 42 to zero; pulse G sets 15 in operation and signal S determines whether additional weights Z are to be added or removed. In the embodiment described, n= 1 and a weight increment of 2 is set on a switch in 15 (Fig. 4, not shown). A signal on lead two is fed from 15 to NAND-gates 71 which sends a signal 0001 to 72. Logic circuit 80 (NOR and NAND gates) receives signals O, S from 17 and a signal UR or UV from counter 41 when the count changes from 9999 to 0000 or viceversa; the corresponding output X, Y is then 10, 01 or 00 which is added to the 0001 in 72 whereby a signal 0011, 0010, or 0001 is passed to store 42. Logic circuit 44 produces a "standstill" signal UN<SP>1</SP> when direction indication pulses V and R cease or alternate (indicating oscillation about a grating line) and unit 63 also fed by pulses V and R, and a signal derived from UN<SP>1</SP>, conditions the pointer 43 and ensures that store 42 is locked long enough for the printer to operate.
