    Abstract: A process for reacting in a fluid bed reactor at least one oxidisable reactant with molecular oxygen in the presence of a catalytically active fluidised bed of solid particles. In the process a molecular oxygen-containing gas having an oxygen concentration greater than that of air is introduced into the fluidised bed whilst the fluidised bed is maintained in a turbulent regime. The process is suitable for oxidation, ammoxidation and carboxylation processes, including the production of maleic anhydride, acrylonitrile, ethylene, acetic acid and vinyl acetate.

    Abstract: Process for the conversion of synthesis gas to hydrocarbons, at least a portion of which are liquid at ambient temperature and pressure, by contacting the synthesis gas at an elevated temperature and pressure with a suspension comprising a particulate Fischer-Tropsch catalyst suspended in a liquid medium, in a reactor system comprising at least one high shear mixing zone and a reactor vessel. The process comprises passing the suspension and synthesis gas through the high shear mixing zone(s) where the synthesis gas is broken down into gas bubbles and/or irregularly shaped gas voids; discharging suspension having gas bubbles and/or irregularly shaped gas voids dispersed therein from the high shear mixing zone(s) into the reactor vessel; and introducing a liquid coolant into the reactor system.

    Abstract: A system and method for performing an electrosurgical procedure are disclosed. The method includes obtaining information indicative of at least one physical characteristic of the patient and generating a reference voltage that is derived, at least in part, from the information. The reference voltage is coupled to a body of the electrosurgical apparatus, and the reference voltage is generated to a level so as to limit any difference between a voltage of the patient and a voltage of the body of the electrosurgical apparatus. In variations, the reference voltage is varied on an ongoing basis so as to adapt the reference voltage to one or more changing physical characteristics of the patient.

    Abstract: A system and method for performing an electrosurgical procedure are disclosed. The method includes applying an active electrode to a patient and placing a return electrode on the patient so as to create a current path in tissue of the patient between the active electrode and the return electrode. A conductive element, which is operatively coupled to the active electrode, is coupled to a reference voltage with a low impedance path and a voltage is imparted to the active electrode so as to generate current in the current path. Any undesirable current flow that would otherwise flow from the active electrode to the reference voltage through the patient is limited to reduce a risk of harm to the patient.

    Abstract: A continuous gas fluidized bed process for the polymerization of olefins, especially ethylene, propylene, or mixtures thereof with other alpha-olefins by cooling the recycle gas stream to condense some liquid (e.g., a comonomer), separating at least part of the liquid and spraying it under pressure through a nozzle (1) directly into the fluidized bed by pressurizing the liquid and feeding it to a spray nozzle (1) having a mechanical device (6) for atomizing the liquid, under conditions such that the spray is formed within a spray-forming zone (5) of the nozzle outlet. The spray-forming zone (5) is preferably shielded from the fluidized bed particles by a wall or walls which can be, for example, a tube or a plate. Also described is a nozzle having two or more series of outlets, each series being fed and controlled independently to enable improved turn-up/turn-down of the liquid supply to the bed.
