Title: Catalytic hydrocarbon conversions and aluminium halide catalysts therefor
IPC: B01J27/06
Filed: 1947-05-14
Abstract: Hydrocarbon conversions are effected in the presence of a preformed liquid aluminium halide-hydrocarbon complex obtained by interaction of an aluminium halide and aromatic hydrocarbon in the presence of hydrogen halide in molar ratios of 1 : 0.3-1.6 : 0.2-0.5 respectively, particularly 1 : 0.7 : 0.33.  Aluminium chloride may be mixed with benzene, toluene, xylenes or mixtures of aromatic hydrocarbons, e.g. extracts of naphthas, kerosenes or gas oils obtained from petroleum, crude oils or other carbonaceous materials which may include paraffin, at temperatures which may range from below room temperature up to about 150 DEG  C., hydrogen halide being added as by bubbling in the gas.ALSO:Hydrocarbon conversions are effected in the presence of a preformed liquid aluminium halide-hydrocarbon complex obtained by interaction of an aluminium halide and aromatic hydrocarbon in the presence of hydrogen halide in molar ratios of 1 : 0.3-1.6 : 0.2-0.5 respectively, particularly 1 : 0.7 : 0.33.  Aluminium chloride may be mixed with benzene, toluene, xylenes or mixtures of aromatic hydrocarbons, e.g. extracts of naphthas, kerosenes or gas oils obtained from petroleum, crude oils or other carbonaceous materials, which may include paraffins, at temperatures which may range from below room temperature up to about 150 DEG  C., hydrogen halide being added as by bubbling in the gas. Examples illustrate the effect of varying ratios of aluminium chloride to aromatic hydrocarbons in isomerizing dimethylcyclopentane to methylcyclohexane and of varying amounts of hydrogen chloride on the homogeneity and activity of the catalyst and evolution of hydrogen chloride during its use.  Isomerization of naphthenes, for example those having 5 or 6 carbon rings, and their alkyl derivatives, of paraffins or hydrocarbon mixtures containing them is effected from about room temperature to 200 DEG  C., preferably 60-150 DEG  C., at atmospheric pressure or above.  Other reactions specified are alkylations of isoparaffins with olefins, e.g. ethylene up to normally liquid olefins, and aromatic hydrocarbons with olefins, diolefins or cycloparaffins.

Filed: 1964-03-31
Abstract: 1,064,949. Paper making. WILHELM HOLZHAUER, ATEX - HOLZSTOFF & HOLZFASER-ISOLIERPLATTENFABRIK KOMM GES. March 31, 1964, No. 13084/64. Headings D2A and D2B. A flocculating agent is added to a suspension of pulp immediately before deposition of the pulp on the screen of a Fourdriner machine in order to coagulate the fibres and any other materials in the suspension, such as fillers, binding agents, adhesives &c. and thus to assist in the dewatering of the web. The method is particularly applicable where the fibrous materials are normally difficult to dewater on a Fourdrinier screen. As shown a spray device 7 is used to apply a solution e.g. of aluminium sulphate to the pulp stream immediately prior to its flow over a rotating roller 5 on to the screen of a Fourdrinier 3. Coventional table rolls, suction devices 9 and press rolls 10 are used to dewater the web.

Title: Self-adjusting Movable Joint Device
Inventor: SCHEUBLEIN WILLIAM ARTHUR
IPC: F16C11/04
Filed: 1968-03-18
Abstract: 1,188,599. Wear-compensated joints. MOOG, INDUSTRIES, Inc. 18 March, 1968, No. 13088/68. Heading E2F. A self-adjusting, . wear-compensated joint comprises a housing 15 for a stud 21 with an axial extension 25 carrying projecting arms 26 which act on inward projections 34 on the ring 31 threaded in an outer ring 30 and forming an abutment for the upper surface of the stud at surface 39. If slack develops at this surface, rotation of the stud in one direction causes the ring 31 to rotate so that it moves towards the stud on its thread and takes up the slack. Overtightening is avoided by selecting the stiffness of the projections 34 and associated "stiffeners" 35 so that they bend away from arms 26 when the frictional force between the stud and surface 39 reaches the required level. Movement of the ring 31 in the reverse direction with consequent slackening of the joint does not occur since the stiffeners 35 do not act on projections 34 which thus move out of engagement with arms 26 under conditions of lower friction. Other embodiments operating on the same principal are described with reference to Figs. 4-11 (not shown).

Title: Process for the isomerisation of saturated hydrocarbons
IPC: C07C9/16
Filed: 1959-04-20
Abstract: <PICT:0844837/IV(b)/1> In the isomerisation of a saturated hydrocarbon fraction heavier than pentane, the feed is introduced into a first fractionation zone to the upper portion of which is fed a liquid stream from the bottom of a second fractionation zone; vapour from the first zone is fed to the bottom of the second zone; bottoms from the first zone are isomerised to convert low octane hydrocarbons to higher octane isomers; the isomerisate is passed to an intermediate portion of the second fractionation zone; vapours from the second zone are recovered as product and bottoms are partly recovered as product and partly fed to the top of the first zone.  A hexane fraction may be fed by line 1 to fractionator 2 which is also supplied by line 23 with a liquid bottoms stream from fractionator 12.  Isohexanes are removed by line 24 and fed to the bottom of fractionator 12, while n-hexane together with slightly branched hexanes if desired pass by line 3 to heater 4 and isomeriser 6. Isomerisation is preferably effected in the presence of hydrogen added by line 10 and a platinum-alumina-halogen catalyst. Alternative supports are silica, alumina, silica-alumina, silica-alumina-magnesia, silica-alumina-zirconia and silica-zirconia having a surface area of 25-100 square metres per gram and alternative catalysts chromium, molybdenum, tungsten, iron, cobalt, nickel, palladium, ruthenium, rhodium, osmium or iridium.  Supported platinum catalysts may also have 5-20% of aluminium chloride deposited thereon.  Aluminium chloride or bromide sludge catalysts may also be used.  General conditions are 150-455 DEG C. and 6,5-70 atmospheres, preferably with vapour phase operation using a L.H.S.V. of 0,1-10, a fresh feed to fresh + recycle feed ratio of 1-5 and a hydrogen to hydrocarbon mol ratio of 0,25-10.  The effluent is passed to separator 8 where hydrogen is separated and recycled and then fed by line 9 to a mid-section of fractionator 12, after debutanisation in fractionator 28 if desired.  A high octane product is recovered overhead by line 17 and a lower octane product is obtained as bottoms, part being recovered as product by line 21 thereby preventing build-up of cyclic materials and part being passed by line 23 to fractionator 2.  If desired fractionators 12 and 2 may form a single column with recovery line 21 forming a draw-off line at a mid-point.
