Title: Improved process for the gasification of carbonaceous materials and for the manufacture of water gas therefrom
IPC: C10J3/46
Filed: 1946-09-10
Abstract: <PICT:0621512/III/1> Process for maintaining the temperature in a reaction zone wherein solid carbonaceous materials suspended in a gas are undergoing an endothermic reaction comprises withdrawing a portion of the carbonaceous material from the reaction zone and bringing it into contact with air under combustion conditions for a period of less than 5 seconds and preferably less than 1 second, separating the combustion gases and returning the heated solid carbonaceous material to the reaction zone.  In an application to the production of water-gas, finely divided coal in the form of a fluidized bed is undergoing gasification in a generator 3, carbonaceous solid is withdrawn through the standpipe 15, combusted with air admitted through the line 17 in the line 18, at temperatures between 1600-2200 DEG  F.  Solids and combustion gases being separated in the zone 19 and the heated solids returned to the generator 3 via the lines 21 and 4, steam being added by the line 22. The generator is maintained at a temperature between 1500-2100 DEG F. and at a pressure ranging from atmospheric to 100 lbs./sq. inch.

Abstract: 730,786. Coking and gasifying powdered coal. KOPPERS GES., H. Nov. 20, 1951 [Nov. 20, 1950; Jan. 8, 1951], No. 27205/51. Class 55 (1). Pulverized coal is mixed with air or oxygenenriched air to form a homogeneous suspension which is injected into a reaction chamber wherein a small portion of the coal and some volatiles are burnt and the rest of the coal is degasified, this coke being separated from the gas produced. Steam may be included in the reagents to obtain a gas resembling water gas. Coal dust from a hopper 1 is mixed with compressed air from a line 4 and blown into a reaction chamber 6, air at 450‹-500‹ C. also being introduced through an annulus 7. Coke dust separated in a chamber 9 from the gases is burnt in a boiler furnace 26. The gases pass through a waste heat boiler 11, heat exchanger 12 supplying the preheated air for the reaction chamber, dust separator 15, electrostatic precipitator 17, and scrubber 19, further solids recovered being fed to the boiler furnace. In plant utilizing oxygen for the reaction, ground coal and oxygen from a mixer 108 is injected into a conical zone 109 opening into a reaction chamber 110 having a water-cooled base 111 for reception of solid residues containing about 2-3 per cent of volatiles. The gases pass through heat exchangers 113, 115, and a separator 118. Steam entering exchanger 115 through an inlet 120 is superheated by contact with tubes 122 of exchanger 115 and by helical passage through a jacket 124 of exchanger 113; being then supplied to the oxygen-fuel mixer 108.

Abstract: 535,478. Locking levers. C. A. V., Ltd., NICOLLS, W. E. W., and EVANS. F. M. Oct. 9, 1939, No. 27518. [Class 80 (iii)] Consists in means for preventing movement of any one or more of a plurality of associated control levers excepting when another or others of the levers is or are in a pre-determined position or positions. A hollow cylindrical fixed bearing member a is formed or provided on the inner surface of one side of a casing f having openings g through which the levers project. Within this member is a rotatable spindle b formed on or associated with one of the levers c, whilst rotatably mounted on the member is a sleeve e formed on or associated with the other lever d. A radial aperture h in the member a houses a locking device, e.g. a ball or roller i. The outer surface of the spindle b and the inner surface of the sleeve e are each formed with one or more recesses j with which the locking piece can engage. When the locking member, which is of slightly greater diameter than the thickness of the member a, engages a recess j in either of the member b, e it is clear of the recess in the other of these members. Thus, as shown, the lever c is locked and cannot be moved until the other lever d is brought to the position in which the recess in the sleeve e lies opposite the locking piece. By making the recesses j sufficiently wide the levers may have a limited degree of freedom while in the locked position.

The impregnated fabric may be dried, stored, fabricated into a garment, pressed and remoistened with water before treatment with formaldehyde. Alternatively the fabric may be continuously precured by applying the aqueous catalyst solution, adding moisture if necessary and then exposing the fabric to formaldehyde vapour. Preferably the fabric contains 60-100% or more of moisture. The water may be applied by padding, fogging or spraying.
