Title: Hydrocarbon conversion processes and catalysts
IPC: C07C5/27
Filed: 1971-03-12
Abstract: 1386801 Isomerizing alkylaromatic hydrocarbons IMPERIAL CHEMICAL INDUSTRIES Ltd 28 Feb 1972 [12 March 1971 3 May 1971] 6674/71 and 12738/71 Heading C5E Alkyl aromatic hydrocarbons are isomerized in the presence of a silica/alumina catalyst of which the alumina content has been lessened by from 1 to 35% of the total alumina originally present, the catalyst comprising before such treatment 7 to 40% wt. alumina and after treatment at least 6% wt. alumina. In particular, a mixture of xylenes containing less than the equilibrium concentration of paraxylene (or alternatively orthoxylene) is isomerized to give a product having a higher concentration of paraxylene (or orthoxylene). The original mix- 'ture may comprise meta-xylene, ethyl benzene, ortho- and/or para-xylene. Isomerization conditions are 200 to 600 C., 0À5 to 50 atmos. pressure and the presence of 100 to 10,000 p.p.m. of steam based on the xylenes.

Title: A process and apparatus for the batch distillation of liquid mixture
IPC: B01D3/02
Filed: 1937-03-06
Abstract: <PICT:0476280/III/1> A process for separation of liquid mixtures in which their components are distilled by batch distillation wherein the liquid mixture to be distilled is fed continuously from a feed tank to a distillation zone wherein a light product in the gaseous phase and a heavy product in the liquid phase are simultaneously separated off.  The mixture thus subjected to distillation is continuously withdrawn from the distiller, such mixture being returned to the storage tank or passed to a second storage tank in which latter case the storage tanks are used alternatively.  Mixture from a storage tank 1 is passed by a pump 3 through a pipe 2 to a distillation zone 5, heavy liquid materials being withdrawn from the bottom by pipe 12 and gaseous light materials from the top by pipe 6a to a line 9.  Some of the lower mixture may pass through the heater 6 and is returned to the bottom of the distillation column 5, whilst at the top, vapours of the light product are condensed in a condenser 7, and a portion of the condensate is returned as a reflux into the main column.  Liquid flowing down in the column is returned to the storage tank 1 through a conduit 10 and a heat exchanger by means of a pump 11.  Owing to the inlet of the tank 1 being at a higher level than the outlet, circulation of the mixture in the tank is promoted.  Both the delivery pump 3 and the return pump 11 are fitted at the tank side of the heat exchanger.  The return pipe 10 may be passed to a second tank which may become the supply tank when the tank 1 is exhausted, the two tanks being used alternatively.

Abstract: 1441881 Refrigerators PRESTCOLD Ltd 21 Feb 1975 [14 Feb 1974] 6822/74 Heading F4H [Also in Division F1] In a gas compressor, e.g. in a refrigeration circuit, comprising a pump 1 driven by an electric motor 2, the windings of the motor are cooled by diverting part of the gas flow upstream of the pump through a passage 4 containing a solenoid valve 5 which is controlled in dependence on the temperature of the windings. As shown, the passage 4 is formed in the casing of the pump/motor unit and diverts part of the main gas flow from a point A, via the solenoid valve 5 and the windings of the motor 2, back to a point B immediately upstream of the pump inlet. An electronic controller 6 for the valve 5 includes in its circuit a number of thermistors located at different positions in the motor windings, the arrangement being such that when a fan 3 fails to maintain the windings below a predetermined temperature, the controller 6 opens the valve 5.

Abstract: 249,139. Naamlooze Vennootschap Internationale Oxygenium Mij Novadel. March 11, 1925, [Convention date]. Bleached products ; treatment by damping or heating ; treating with air and gases, with solid substances, with radiations; mixing and agitating. - To improve the appearance and other qualities of meal, flour or milling products one or more organic acid anyhdrides and one or more aldehydes or a mixture of one or more of said anhydrides with one or more aldehydes, or substances which contain or set free these compounds are added to the flour, these materials reacting with air or oxygen present in or poured into the flour, and so producing a flour-improving substance actually in the flour. Oxygen or gases containing or setting free oxygen or mixtures which can liberate oxygen is or are blown through the flour &c. and added materials. As specific examples of the process (i) benzaldehyde and acetic anhydride or (ii) acetaldehyde and acetic anhydride or (iii) butaldehyde and succinic acid anhydride are successively injected into wheat flour after which air is blown through for some time. Anhydrides and hydrogen peroxide or peracids and anhydrides may be used the blowing through of air not then being necessary. Catalyzers such as salts of chromium, cobalt, iron, uranium and vanadium may be used with materials setting free the flour-improving substances, such catalyzers being used with or in place of weak alkaline reacting materials. Any acid-reacting, material produced in the flour during the process may be neutralized by the addition of an alkaline substance such as bicarbonate of soda. Oxygen may be passed through the flour containing the materials to produce the flour-improving substance, or compounds to produce oxygen may be mixed with the materials. Heat may be applied to the flour containing the materials. The activity of the materials may be increased by mechanical or physical treatment, such as stirring, exposure to ultra-violet light, or the like. The flour or meal may be dropped down a tower and the added substances blown in the opposite direction, or the flour or the like may be carried in a thin layer through a room in which the added substances are atomized.
