    CPC classification number: H01S3/09

    Abstract: A system for the irradiation of a target with electromagnetic energies covering the region between approximately the infra-Xray and the trans-infrared portions of the spectrum comprises: light associated with a shock wave front aligned to strike a tape valve comprising a movable tape, impervious to said shock wave, having a mirror-like surface and also at least one aperture in spaced relation to said surface and means for moving said tape at a speed such that said light strikes the mirror-like surface and said shock wave front passes through said aperture; a shock sensitive irradiable target optically coupled to said mirror-like surface and said movable member, whereby to provide via said movable member a light-coupling between said target and light source.

    Abstract: Process of dehydrocyclizing C6-C10 hydrocarbons using a lithium, sodium or potassium zeolite X or a lithium, sodium or potassium zeolite Y which zeolite has been impregnated with from 0.10 to 1.2 wt. percent platinum and from 0.10 to 1.2 wt. percent rhenium and then reduced with hydrogen to the free metal. The dehydrocyclization reaction is carried out at from 500* to 560* C. and preferably from 510* to 555* C. using a partial pressure of hydrogen of from 10 to 300 p.s.i.g. and preferably from 50 to 200 p.s.i.g. to form benzene and alkylbenzenes.

    Abstract: SELECTIVE ADSORPTION OF P-XYLENE FROM A FLUID MIXTURE CONTAINING M-XYLENE CAB BE OBTAINED WITH COPPER-EXCHANGED MOLECULAR SIEVES (CRYSTALLINE ALUMINO-SILICATE ZEOLITES) WHICH HAVE A WATER LOSS ON IGNITION AT 800* C. IN THE RANGE OF 8-20 WT. PERCENT AND PREFERABLY, HAVE BEEN PARTIALLY DEHYDRATED AT A TEMPERATURE IN THE RANGE OF 50-300* C. PREFERABLY THE AL/SI RATIO IN THE ZEOLITE FRAMEWORK IS IN THE RANGE OF 0.2-0.65. FOR EXAMPLE, P-XYLENE CAN BE SEPARATED FROM M-XYLENE BY SELECTIVE ADSORPTION AT 100* C.
