Patent GB-824061-A (GB)
Title: Improvements relating to the production of benzene
IPC: C07C4/18
Filed: 1957-08-08
Abstract: Benzene is prepared from relatively a aromatic-free hydrocarbon feedstock, a major proportion of which boils below 100 DEG  C.  by aromatizing at at least 450 DEG  C. and not more than 50 p.s.i.g. over a chromia-alumina catalyst, subjecting the liquid product to catalytic dealkylation and recovering benzene by solvent extraction and/or distillation.  The feedstock may be a straight run petroleum or a lowboiling hydroformate fraction, e.g. a platformate, boiling in the range 35-120 DEG  C.  The aromatization is preferably effected at atmospheric pressure at a space velocity of 0.1-1 vol./vol./hr. with no addition or recycle of hydrogen.  The catalyst may be promoted with potassium and/or cerium, boron, bismuth, germanium, nickel or manganese, or with a spinel such as cobalt, iron or copper chromite or zinc titanate. The dealkylation is preferably effected with a complex catalyst of nickel deposited on a base prepared by impregnating alumina with a nickel salt, calcining at above 650 DEG C. and preferably extracting with an inorganic acid.  The catalyst is preferably reduced before use and may contain in the base 1-50% of nickel by weight of the base and a further quantity deposited on the base of 1-30% by weight of the catalyst.  Hydrogen (e.g. from the aromatization) is preferably present in the dealkylation which may be effected at 250-500 DEG  C. and 0-200 p.s.i.g. Recovery is conventional.

Abstract: 428,181. Strapping boxes. PRESTWICH, J. V., Tariff Road, Tottenham, London. Aug. 31, 1934, No. 25092. [Class 45] [See also Group XXII] In a machine in which a lever 30 operates one or more cams 27 actuating the sealing die or dies 22, the movement of the lever to separate the dies after sealing releases the grippers of the tensioning device. The lever 30 may be held in this releasing position by a clip or ratchet device 66. The tensioning device comprises a slide 48 moved to and fro by a hand-lever 52 and carrying gripping rollers 53, 57, and a second pair of stationary gripping rollers 53<a>, 57a. The upper rollers 57, 57d are fixedly mounted on levers 56 and are pressed by springs 58 into contact with the band. The levers 56 are mounted so that the rollers hold the band against movement to the left, but the grip is released when the sealing lever 30 bears upon lateral extensions 62 of the levers 56. In operation, the free end of the band is laid over projections 34 and passes between the die-plates 26, 33 and under an eccentrically mounted gripping roller 36, then round the case, between the die plates again and through the tensioning device. After tensioning, the die 22 is forced down to form the seal described in Specification 428,166, [Group XVII], and this movement of the die cuts the upper band between a block 41 and a cutting edge 44. In a modification, Fig. 10 (not shown), the cutter 44 is adjustable vertically on the die 22. The cutter block 41 is supported on a spring 43 and in operation is pressed down into contact with a vertically adjustable stop. After sealing, the reverse movement of the lever 30 and cam 27 raises the die 22 by means of the spring plunger 32. In sealing, the cam acts on the die through an inset roller 31. A catch 39, Fig. 6, pivoted on the base is raised as shown when the lever 30 is in the releasing position to permit insertion and removal of the band, but when the lever 30 is raised the catch falls and holds the superimposed parts of the band in the correct position between the dies.

Title: Improvements in or relating to method and apparatus for deodorizing oils and fats
IPC: C11B3/14
Filed: 1949-10-10
Abstract: <PICT:0704232/III/1> Fatty oils and fats are deodorized in sequential batch treatment by passing the batch of oil to a preliminary heating zone where it is heated to a point below effective deodorization temperature and also deaerated, then to a series of zones where heating at the effective deodorization temperature is effected and in one of which a stripping medium is passed therethrough to effect deodorization, and finally to a cooling zone, the batch remaining in each zone for the same time interval.  Each zone of treatment may be subjected to vacuum.  Preferably, five zones are used to effect (1) deaeration at a temperature below effective deodorization temperature, (2) heating to deodorization temperature, (3) deodorization, (4) deodorization, and (5) cooling.  Suitable apparatus employing the five zones comprises a cylindrical column 33 with the five zones 1 . . . . 5 defined by superposed square trays 36 having side walls 37, each provided with steam stripping inlets 12 . . . . 16, and zone 1 having steam heated coils 17, zones 2 and 4 having diphenyl and diphenyl oxide vapour heated coils 20 and 21, and zone 5 having a cooling coil 28.  The batch of oil is supplied to the top of the column through an inlet 43 and flows from tray to tray through delivery pipes 47, 49, 51, 53 to a final discharge pipe 55 each provided with valves 46, 48, 50, 52, and 54.  Reduced pressure is maintained within the column by a steam jet ejector system connected at F1.  A system of baffles is provided at the top of each tray comprising a number of open square plates 18, 19 nested one within another and interconnected in spaced relationship by angle pieces, to provide a tortuous path for the escape of vapours therefrom and to splatter the oil which is thrown upwardly against them by the stripping steam, the normal oil level being indicated at L.  In an example, cottonseed oil is treated for half hourly periods with stripping steam in each zone, at 320 DEG F., in zone 1 to preheat and remove air which flows out through F1, at 460 DEG F, in zones 2 and 4 with interposed stripping alone in zone 3 the odorous vapours also flowing out through F1, and finally at 130 DEG F. in zone 5 to cool it below oxidation temperature stripping steam still being supplied.  Soya bean oil and lard are also exemplified.  The trays and associated parts coming in contact with the oil may be made of nickel or aluminium, and the shell of the column may be made of ordinary carbon steel.  The process also removes free fatty acids from the oil being treated. Specifications 505,810, 510,852 and 704,298 are referred to.
