Title: Improvements in or relating to the separation of the isotopes of lithium
Inventor: SAITO EICHI
IPC: B01D59/32
Filed: 1959-04-21
Abstract: Isotopes of lithium are separated in a process which comprises passing Li amalgam in countercurrent contact with an organic solvent solution of a Li salt, a first circuit wherein Li in the solution leaving the contact is extracted and converted to amalgam, which is returned to the contact, and a second circuit wherein Li in the amalgam leaving the contact is extracted and converted into salt <PICT:0872343/III/1> <PICT:0872343/III/2> <PICT:0872343/III/3> solution, which is returned to the contact.  The solvent should be inert and a conductor, and salt solutions may be LiCl in dimethyl formamide, or LiBr in dimethyl formamide or tetrahydrofuran.  In Fig. 1 amalgam passes in fine drops from 7 through column 1, while Li salt solution enters at 8.  The salt solution, enriched in 7Li is treated in evaporator 2 to remove solvent, the salt is dissolved in water, and the resulting solution is passed to electrolyser 3 having a mercury cathode, whence amalgam is returned to 1.  The amalgam enriched in 6Li is treated with an aqueous solution of hydrogen halide in separator 4 whence Hg passes through 11 to electrolyser 3. The resulting salt solution is passed to evaporator 5 and the salt is dissolved in tank 6 in solvent returned from evaporator 2 by 9. Alternatively, in Figs. 3 and 4 amalgam enters pulsed column 13 at 23 and the salt solution is withdrawn at 26 to electrolyser 14, where water is injected at 22 to increase conductivity, and compressed air entering at 19 flushes out halogen at 20.  The resulting H2O-solvent mixture is passed to distillation column 15 for separation of solvent, which is passed at 30 to saturator 17 and is saturated with hydrogen halide gas.  The saturated solvent is fed to separator 16 where it contacts amalgam entering through 24 from column 13 and the resulting salt solution is returned to the column at 25 while Hg is returned through 27 to electrolyser 14. Figs. 5 and 6 (not shown) show the series connection of stages to form cascades involving either transfer of part of the 6Li enriched solution returning from the second circuit to the column to the next succeeding column at a point of identical isotopic concentration, and return of solution leaving that column to the preceding column to yield a final 6Li enriched salt solution (Fig. 5) or transfer of part of the 7Li endiched solution leaving the contact column to the next succeeding column at a point of identical isotopic concentration, and return of solution entering that column from the second circuit to the preceding column to yield a final 7Li enriched salt solution (Fig. 6). The transfer from stage to stage may be by means of the amalgam and the two cascades of Figs. 5 and 6 may be grouped together for simultaneous concentration of 6Li and 7Li.

Title: Improvements in hydrocarbon gasification processes
Inventor: LOM WALTER LOWENSTEIN
IPC: C10G47/00
Filed: 1963-04-05
Abstract: In the production of town gas by steam reforming of a hydrocarbon in which part of the hydrogen-containing product gas is recycled to the reforming zone, gases heavier than hydrogen are removed from the recycle gas by passage through an adsorbent bed, and the spent bed is desorbed by the passage of the remaining product gas at a lower pressure.  The two gas streams may be passed alternately through two beds of adsorbent material.  As shown the product of steam-reforming of sulphur-containing naphtha is divided into two, one stream at 30 atm. is directed through active charcoal <PICT:0992161/C4-C5/1> bed 1, wherein CO, CO2, N2 and hydrocarbons are adsorbed, and from which the effluent at 28 atm. is recycled to the reformer, and the other stream is evacuated to e.g. 15 atm., passed through charcoal bed 2 to desorb the gases adsorbed in a previous cycle, and withdrawn as product.  The two streams are periodically "switched" by means of valves 3 to 8.  Before reforming, the sulphur content of the feed is reduced to <1 ppm (for preferred 50% nickel oxide catalyst), or <5 ppm (15-20% nickel oxide) by sulphuric acid treatment hydrofining, and H2S removal.  Specifications 850,443, 965,565 and 965,566 are referred to.
