Title: Improvements in or relating to the production of branched chain hydrocarbons
IPC: C07C5/27
Filed: 1958-04-22
Abstract: Normal paraffins having 3-8 carbon atoms/molecule and isoparaffins having 4-8 carbon atoms/molecule are subjected in the vapour phase and in the presence of ethylene to high energy ionising radiation at a dose rate and for a time such that 10-6-103 KWH is absorbed per lb. of hydrocarbon feed, whereby branched chain homologues and/or isomers are produced. Suitable paraffin feed stocks are C4 and C5 cuts from thermal or catalytic cracking, field butanes which have been subjected to isomerisation or partial dehydrogenation, spent gaseous and liquid products from catalytic polymerisation, refinery feed boiling in the range 10-200 DEG F. and containing at least 75% of the desired paraffin/ethylene mixture and Arabian virgin naphtha having a high concentration of C5-C7 paraffins.  If desired, the feed may be produced by first subjecting a paraffin e.g. butane or isobutane to steam or radiation cracking to give either ethylene (which is added to the desired paraffin) or to give directly a mixture containing a suitable quantity of ethylene.  Where radiation cracking is employed the two radiation zones may be combined.  The amount of ethylene present is preferably 0.1-30% of the paraffin plus ethylene in the feed: the reaction may be self-supporting in regard to ethylene.  The products are normally branched chain hydrocarbons boiling in the range 65-430 DEG F.: Tables are given of products which range from hydrogen to C9 and higher hydrocarbons, mainly saturated and olefinic.  When using n- or iso-butane, the product is predominantly isopentane.  In the preferred process the paraffin/ethylene mixture is continuously passed into the reaction zone and product continuously removed therefrom, unreacted hydrocarbons are separated conventionally and recycled with make-up ethylene and paraffin.  The use of a fluidised bed of molecular seive for separation is also referred to.  A diluent such as a refined mineral oil may if desired be added to the reactants.  The reaction is preferably carried out at 300-1000 DEG F. and 10-1000 p.s.i.g.  Suitable radiations are y-rays, X-rays, b -rays, a -particles, neutrons and accelerated electrons; specified sources include fission by-products and waste-products, Co-60, and nuclear reactors in which the hydrocarbon may itself function as the moderator.

K. ; Central Avenue, Hartsdale, New York, U.S.A.) May 5, 1932, No. 12930. Convention date, July 7, 1931. [Classes 40 (iii) and 40 (v).] In order to eliminate interference which bears a definite frequency-relationship to the desired signal, such as the so-called " image " frequency in supersonic reception, the secondary S of the input circuit is tapped at the point 14 so as to form two paths. One comprising the winding S1 and condenser C1 forms a seriestuned shunt circuit to earth for the undesired or " image " frequency, whilst the other comprises a heavy-impedance primary P2 which transfers to the first valve voltages of the desired frequency flowing in the tuned circuit S1, C1. The equivalent circuit is shown simplified in Fig. 3. The reduction of voltage due to the tapping may be compensated by adding a second open-circuited winding P12' Fig. 7, to the primary P. The link circuit 11 may be tuned below the wave-band range by means of a condenser C3, Fig. 4, in order to maintain constant coupling at the lower end of the tuning scale ; the coil P2 may be closely coupled to the high-potential end of the coil S2 for the same purpose. Fig. 5 shows a modified form of coupling in which the link circuit 11 is designed to give a better response at high frequencies ; whilst Fig. 7 is another arrangement having the same property.
