    摘要: The present invention concerns a process for the synthesis of hydrocarbons from a feed comprising synthesis gas, in which a solid catalyst comprising cobalt is used in a three-phase reaction section operated such that said catalyst is maintained in suspension in a liquid phase by movement of a gas phase from the bottom to the top of said reaction section, said process comprising an external loop for separating waxes, characterized in that: 1) the theoretical ratio PH2O:PH2 in the external loop for separating waxes is determined using the following calculation: PH2O:PH2 theoretical=Cv/(R1−Rft×Cv) where Cv=(COinlet−COdegas)/COinlet R1=H2 inlet/COinlet Rft=(H2 inlet−H2 degas)/(COinlet−COdegas) 2) if the theoretical ratio PH2O:PH2 determined in step 1) has a value of Rthreshold or higher, the temperature in the degassing means for the external loop for separating waxes is reduced, 3) steps 1) to 2) are repeated until the theoretical ratio PH2O:PH2 has a value strictly less than Rthreshold, where Rthreshold is in the range 0.1 to 1.1.

    摘要: A process for the production of hydrogen cyanide comprises feeding a reaction mixture feed to a plurality of primary reactors each comprising a catalyst bed comprising platinum, wherein the reaction mixture feed comprises gaseous ammonia, methane, and oxygen gas, determining whether a percent yield of hydrogen cyanide in any of the plurality of primary reactors is at or below a threshold, identifying one or more suboptimal reactors amongst the plurality of primary reactors when the percent yield of hydrogen cyanide in any of the plurality of primary reactors is at or below the threshold, and supplementally feeding the reaction mixture feed to one or more supplementary reactors when the one or more suboptimal reactors are identified, wherein each of the one or more supplementary reactors comprises a catalyst bed comprising platinum. The supplemental feeding can be performed in place of the feeding of the reaction mixture feed to the one or more suboptimal reactors or in addition to the feeding of the reaction mixture feed to the one or more suboptimal reactors. The overall process is sufficient to maintain an overall measured hydrogen cyanide production rate amongst the one or more supplementary reactors and the primary reactors that is within a desired overall hydrogen cyanide production rate range.

    摘要: A method and associated instrument are disclosed for increasing the sequential rate at which a series of microwave assisted chemical reactions that potentially generate high pressure can be carried out. The method includes the steps of opening a pressure-resistant valve on a microwave-transparent pressure-resistant vessel to define a unpressurized pathway through the valve into the vessel, inserting a tube through the pathway in the valve and into the vessel, transferring at least one composition into the vessel through the tube, removing the tube from the vessel and from the pathway in the valve, closing the valve to seal the vessel against pressure release, and exposing the vessel and its contents to microwave radiation. The instrument includes a source of microwave radiation, a cavity in microwave communication with the source, an attenuator that forms at least a portion of the cavity, a pressure-resistant microwave-transparent reaction vessel having portions in the cavity and portions in the attenuator, a pressure-resistant valve on the mouth of the vessel, a reciprocating tube for passing through the valve and into the vessel when the valve is open, and means for mechanically inserting and retracting the tube through the valve and into the vessel when the vessel is in the cavity and the attenuator.

    摘要: A resonant shaker includes a support tray for supporting a target carrier. A sensor generates an electrical signal that is related to an acceleration of the support tray. A linear drive motor includes an armature that is coupled to the support tray. The linear drive motor provides an oscillating drive force to the support tray in response to a drive current applied to the linear drive motor. The resonant shaker also includes a controller. The controller receives the electrical signal from the sensor and a drive signal that is related to the drive current. The controller transmits a modified drive current to the linear drive motor in response to a predetermined phase relationship between the electrical signal and the drive signal.
