Title: Process for producing alkyl aromatic hydrocarbons
IPC: C07C17/10
Filed: 1963-05-13
Abstract: <PICT:1039937/C4-C5/1> Alkyl aromatic hydrocarbons are prepared by reacting a paraffinic hydrocarbon with a halogen, separately recovering the alkyl halide and hydrogen halide produced, reacting the alkyl halide with an aromatic hydrocarbon in presence of an alkylation catalyst and separately recovering the alkyl aromatic hydrocarbon product and additional hydrogen halide, reacting the hydrogen halide with a free oxygen containing gas, recovering liberated halogen and recycling the latter to further reaction with the paraffinic hydrocarbon.  The alkylation catalyst is a Friedel-Crafts metal halide in which the halogen is the same as that reacted with the paraffinic hydrocarbon which contains at least two carbon atoms or may contain at least one tertiary carbon atom. Specified paraffin hydrocarbons have 2 to 10 carbon atoms and include methyl derivative and cycloparaffins.  Any halogen may be used, preferably bromine.  The aromatic hydrocarbons used include benzene and derivatives thereof having up to 18 carbon atoms in the side chain, naphthalene, alkyl naphthalenes, anthracene, phenanthrene, naphthacene and rubrene.  Specified catalysts are aluminium chloride or bromide, zirconium chloride, ferric chloride, zinc chloride, bismuth chloride or boron trifluoride. Halogenation of the paraffin takes place at 0 DEG  to 400 DEG  C. and alkylation of the aromatic hydrocarbon at 0 DEG  to 300 DEG  C. at atmospheric to 200 atmospheres pressure.  The hydrogen halide product streams may be combined and reacted with free oxygen containing gas at 50 DEG  C. to 400 DEG  C. in presence of a metal oxide of copper, iron, nickel, cobalt, magnesium and zinc, the latter two may be modified with up to 5% copper, nickel or silver. In a modification, the hydrogen halide is first reacted with the metal oxide and the metal halide formed is subsequently reacted with the oxygen containing gas.  As shown in the Figure, paraffin hydrocarbon is supplied through line 1 and is admixed with recycle halogen from zone 13 and additional halogen added from line 17. Halogenation takes place in zone 2, using up to 20 moles hydrocarbon per mole of halogen, any unreacted hydrocarbon being recycled from separator 4 through line 5, hydrogen halide being passed to halogen regeneration zone 13. Alkyl halide is passed via line 6 to alkylation zone 8 wherein reaction takes place preferably in the liquid phase with aromatic hydrocarbon supplied through line 7, the h.l.s.v. of the feed being 0.1 to 20 and the ratio of aromatic hydrocarbon to alkyl halide being up to 20:1. Unreacted aromatic compound is recycled from separation zone 10 to the alkylation zone, alkylated aromatic hydrocarbon is taken off through line 15 and hydrogen halide is passed to zone 13 for conversion to free halogen and recycle to halogenation zone 2. The examples describe (i) the ethylation of benzene using ethyl bromide, (ii) the propylation of benzene using propyl bromide and (iii) the preparation of butyl benzene in presence of a copper-modified magnesium oxide.

Title: Apparatus and method for carrying out reactions in a fluidised  bed
IPC: B01J8/38
Filed: 1975-07-25
Abstract: 1471598 Rotary fluidised bed apparatus NATIONAL RESEARCH DEVELOPMENT CORP 25 July 1975 [30 April 1974] 18855/74 Heading B1F [Also in Division F4] Fluidised bed apparatus comprises a rotatable drum having a permeable circumferential wall against which the bed is supported in operation and through which the fluidising gas passes. Apparatus for the combustion of a lean air/gas mixture e.g. the exhaust air from a drying oven, comprises a drum 19 rotatable about a vertical axis and having an inner wall 21 of perforated metal supported by an apertured outer wall 22. The drum is supported within a housing 10 rotated by a drive 23, 24 and having an inlet stem 16 sealed into a stationary chamber 26 fed with the air/gas mixture. The top of the housing is closed except for an outlet 38 above which a lipped funnel feed trap 39 is mounted. The bed 20 comprises particles of two size ranges, the finer particles forming the bed as the apparatus is started, and being heated by the combustion of the mixture and auxiliary fuel fed from a nozzle 29 into the feed stem above the seal 27. When the fine particles of the bed reach a sufficiently high temperature, the rate of supply of gases used, the speed of rotation is increased, and the coarser particles form the bed, while the fine particles are collected in the lip of the trap at 41. Copper wool 33 forms a flame trap between the housing 10 and the drum 19. The use of the rotating bed support and coarser particles allows a very high feed rate of the gas/air mixture. The fine particles used for start up may be withdrawn and collected, coarse particles being fed to the bed from a hopper (Fig. 2), or passages from the lip area of the trap may allow circulation of the bed particles (Fig. 3). Solid fuel may be burned or gasified in a fluidised bed in a cylinder 50 rotating about a horizontal axis within a stationary housing 52, Fig. 4. The pulverluent fuel is delivered through a stationary shaft 53 to a shoot 70 directed towards the circumferential wall. A fan 62, separately driven, projects through the open end of the stationary housing, and auxiliary fuel gas may be supplied through a ring pipe 74. The outlet may be stationary and formed of coolant pipes, or may include a trap for finer particles and rotate with the drum 50. Heavy oil may be churned in a bed of inert particles, and lighter oil may be sprayed on to the outside of the drum 50. Inert particles from the bed may be recirculated through a heat exchanger (Fig. 5). The perforations in the wall of the drum may direct the fluidising gases tangentially.

Title: Improvements in or relating to toy watercraft
IPC: A63H29/18
Filed: 1947-07-19
Abstract: 635,502. Toy submarine. BURROUGHS & CO., Ltd., A., and THORP, A. July 19, 1947, No. 19388. [Class 132 (iii)] A toy submarine includes a part or parts exterior to the hull the position of which part or parts varies relative to the remainder of the toy with the degree of winding of a windable resilient driving means, the variation of position of said part or parts being such that the toy is caused to dive and surface. The movable parts are preferably symmetrically arranged hydroplanes. Further parts of the toy may be movable to alter its water line and trim. As shown, the submarine has a wooden body 11 with a central longitudinal slit in its under surface. The windable resilient means consists of one or more rubber bands which pass round a pulley 12 rotatably mounted at the forward end of the slit. One end of the rubber band 13 engages a hook at the forward end of the propeller shaft, the other end of which has a square portion 16a. The other end of the band 13 engages a hook on the hydroplane assembly 17 which is longitudinally displaceable relative to the body 11. Tensioning means 18 comprise a rubber band which engages a hook on the other side of the assembly 17 and is attached at its other end to a hook near the stern. A U-section metal keel 19 engages frictionally in the slot 11 and is pivotally attached to the body by the cross-bar on which the pulley 12 revolves. A rudder 20 is carried on a support bar 21 swingable to one side of the propeller so that the portion 16a of the propeller shaft may engage the winding means as shown. When the resilient means is fully wound the hydroplane assembly is more forward than is shown in the drawing and, as it unwinds, the assembly moves back towards the stem thus causing the submarine to execute dives and surfacings in a rocking motion the amplitude of the dives decreasing until the toy remains on the surface. The centre of gravity may be varied by having a slot in the keel through which a small plate on the outside of the keel is attached to a weight inside so that the weight may be adjusted by moving the plate. Alternatively the centre of gravity may be adjusted by having a rudder bar mounted so as to slide longitudinally, the rudder being rotated about the bar when the toy is being wound. The Provisional Specification describes any toy water craft in which a slowly displaceable part of the resilient driving means operates some other part of the craft ; for instance a toy destroyer may release a torpedo when the resilient driving means reaches a predetermined position.
