  • Patent number: 5244987
    Abstract: A process for controlling the continuous gas-phase polymerization of one or more alpha-olefins in a fluidized and/or mechanically stirred bed reactor using a high activity catalyst based on a transition metal of groups IV, V or VI of the Periodic Table comprises introducing into the reactor, continuously and simultaneously, an activity retarder and an activator, in very small amounts, in a molar ratio and at flow rates which are varied with time in order to maintain substantially constant either the polymerization rate or the transition metal content of the polymer produced.
    Type: Grant
    Filed: February 28, 1992
    Date of Patent: September 14, 1993
    Assignee: BF Chemicals Limited

  • Patent number: 4639929
    Abstract: The method of the invention concerns continuous graphitization of long pre-cooked carbon-containing products.It comprises displacing the carbon-containing products in a column, along a horizontal axis of passage, inside a furnace where the packing is a fragmented carbon-containing material which is not displaced within the furnace. The column is put under stress by rams and is heated by the Joule effect.The method can be applied particularly to the production of graphite electrodes for arc furnaces in steel works.
