Patent GB-967822-A (GB)
Title: Production of olefines
Inventor: ADDY LESLIE ERNEST
IPC: C07C1/36
Filed: 1961-10-13
Abstract: Olefins are obtained by oxidizing paraffins in the liquid phase in the presence of boric acid to obtain alkyl esters of boric acid, heating the product in the presence of sufficient boric acid to give a total boric acid to ester ratio at least equivalent to that in esters of metaboric acid and decomposing the esters by heating to give olefins.  The paraffin feed is preferably a C10-C18 feedstock having at least 95% normal paraffins and is oxidized at 100-300 DEG C. in the presence of 5-10% by weight of boric acid to obtain up to 30% conversion. The product is then heated to 100-300 DEG  C. under superatmospheric pressure, if necessary and with added boric acid if required to give a total boric acid content of at least 62 g. per g. mol. of converted paraffin.  Unconverted paraffins are removed before or after this treatment and recycled.  The esters are finally decomposed by heating to 200-450 DEG  C., removing the olefins as vapours; this stage may be combined with the thermal treatment. The product may be used for preparing detergent alkylate.

Title: Improvements in or relating to a process and an apparatus for separating a constituent from a stream of media
IPC: H02P7/298
Filed: 1959-10-30
Abstract: 939,687. Centrifugal separators. SIEMENS-SCHUCKERTWERKE A.G. Oct. 30, 1959 [Nov. 3, 1958], No. 36964/59. Addition to 933,224. Class 23. The process of the parent Specification is modified in that a body is disposed on the axis of the separating chamber or tube to intercept particles of the stream of material and thus prevent them from passing straight through the chamber directly to the outlet without being subjected to the separating forces resulting from the production of potential and rotary flows. In a dust separator for treating flue gases, Fig. 2, a a body 9, which may be streamlined or have a profiled bottom to facilitate deflection of the particles, is placed axially with respect to the rotary flow. Secondary air is introduced through oblique tangential ducts 3 to create the potential flow. The chamber 1 may be other than cylindrical in shape. In a modification the secondary air is introduced through ducts opening obliquely and outwardly with respect to the chamber axis into the top of the chamber adjacent a central discharge passage for the clean gases and above the central body 9<SP>1</SP>. In Fig. 4 a multistage separator 1 is mounted in a chimney 10. The intercepting body is in the form of a lattice sphere 12 which also provides a rough ground. Lattices 11, 13 form the other rough grounds which, together with the body 12, form mirrorimage potential and rotary flows similar to those described in the parent Specification. The separated particles are removed from the apparatus by an outlet 19 in which suction is created by fluid blown in the direction of the arrows. A separator for removing from steam salt entrained in water particles in a steam boiler is shown in Fig. 5. The potential flow is created by part of the steam-water mixture fed by ducts opening obliquely in the top of the chamber as seen in a direction in the plane of the Figure. It is stated that it has been found in practice that the power required for the introduction of secondary medium to generate the potential flow may be reduced by widening the outlet of the entry tube 2 or by placing a lattice structure over it, as shown in Fig. 4, or again by sucking or tangential blowing of the boundary layer of the stream of material in the tube 2. The potential flow may be stimulated either by the means referred to in the parent Specification or by rotating wire nets in the chamber 1. The rough ground may also be formed by rotating discs. The process may also be applicable to degassing liquids and separating gases.
