摘要： A process for the production of ethylbenzene by the ethylation of benzene in the critical phase over a molecular sieve aromatic alkylation catalyst comprising cerium-promoted zeolite beta. An aromatic feedstock having a benzene content of at least 90 wt. % is supplied into a reaction zone and into contact with the cerium-promoted zeolite beta having a silica/alumina mole ratio within the range of 50-150 and a cerium-aluminum ratio of 0.5-1.5. Ethylene is supplied to the alkylation reaction zone in an amount to provide a benzene/ethylene mole ratio of 1-15. The reaction zone is operated at temperature and pressure conditions in which benzene is in the super critical phase to cause ethylation of the benzene in the presence of the cerium zeolite beta alkylation catalyst. An alkylation product is produced containing ethylbenzene as a primary product with the attendant production of heavier alkylated by-products of no more than 60 wt. % of the ethylbenzene. The critical phase alkylation reaction may be followed by the transalkylation of a polyalkylated aromatic component.

摘要： A process for the production of ethylbenzene by the ethylation of benzene in the critical phase in a reaction zone containing a molecular sieve aromatic alkylation catalyst comprising cerium-promoted zeolite beta. A polyethylbenzene is supplied into the reaction zone and into contact with the cerium-promoted zeolite beta having a silica/alumina mole ratio within the range of 20-500. The reaction zone is operated at temperature and pressure conditions in which benzene is in the supercritical phase to cause ethylation of the benzene and the transalkylation of polyethylbenzene and benzene in the presence of the zeolite beta catalyst. An alkylation product is produced containing ethylbenzene as a primary product with the attendant production of heavier alkylated byproducts of no more than 60 wt. % of the ethylbenzene. The alkylation reaction zone is operated under conditions providing a composite byproduct yield of propyl benzene and butyl benzene relative to ethylbenzene, which is no more than one half of the corresponding yield byproduct for zeolite beta promoted with lanthanum. The production of ethylbenzene in the critical phase alkylation reaction zone is attended by recycle of a polyalkylated aromatic component of the reaction product back to the reaction zone.

摘要： A method for preparing a homogeneous blend of asphalt and ground tire rubber. An asphalt base material is heated to a temperature sufficient to permit the stirring of the asphalt base material within a mixing vessel. A particulate crumb rubber component having a designated average particle size is added to the asphalt base material. The crumb rubber material can be partially devulcanized or partially depolymerized and may be accompanied by the incorporation of another rubber component, such as a ground styrene butadiene rubber. Zinc oxide is added to the asphalt base material. The mixture incorporating the zinc oxide is stirred for a period sufficient to provide for substantial solubilization of the crumb rubber within the asphalt base material to provide a blend which has a higher homogeneity than a corresponding blend of the same asphalt and particulate rubber components which is heated and stirred under the identical conditions, but without the addition of the zinc oxide.

摘要： A process and system for the vapor phase alkylation of an aromatic substrate in a multi-stage alkylation reaction zone having a plurality of series-connected catalyst beds spaced from one another to provide mixing zones between adjacent catalyst beds. A feedstock containing an aromatic substrate and a C2–C4 alkylating agent is supplied to an inlet side of the reaction zone. The reaction zone is operated at conditions in which the aromatic substrate is in the gas phase and causing vapor phase alkylation of the aromatic substrate as the aromatic substrate and the alkylating agent flow through the reaction zone and pass from one catalyst bed to the next. A quench fluid comprising one or both of the aromatic substrate and the alkylating agent is supplied into the interior of the mixing zone through a plurality of flow paths in which one portion of the flow paths is directed upwardly within the mixing zone and another portion downwardly within the mixing zone. Alkylated product is then recovered from the downstream side of the reaction zone. The quench fluid is supplied to the mixing zone through a plurality of dispersion channels which are spaced laterally from one another and extend transversely across the mixing chamber. At least some of the dispersion channels dispense the quench fluid alternately, upwardly and downwardly within the mixing zone.

摘要： A process for the preparation of an asphalt and polymer composition in which a minor amount of polymer component is subjected to a crosslinking. An asphalt base material is heated in a mixing chamber at a temperature sufficient to melt the asphalt and allow stirring of the asphalt within the chamber. A thermoplastic elastomer is added to the chamber in an amount not greater than 12 wt. %. While the asphalt elastomer formulation is stirred, a crosslinking agent is added in an amount effective to crosslink the thermoplastic elastomer. The crosslinking agent formulation comprises at least two components. One component is a thiopolymer incorporating organic sulfur prepared by the reaction of 6-tertiary butyl cresol and sulfur dichloride which reacts to produce a reaction product comprising 4,4-thiobis(6-tertiary butyl-m-cresol) and the thiopolymer, followed by subsequent separation of the 4,4-thiobis(6-tertiary-butyl-m-cresol) from the thiopolymer product. The second crosslinking component comprises a source of sulfur to crosslink the thermoplastic elastomer. The second crosslinking component may be selected from the group consisting of elemental sulfur, polythiomorpholine, specifically dithiodimorpholine, zinc-2-mercaptothiazole and mixtures thereof

摘要： The present invention provides a method for preparing an asphalt and thermoplastic elastomer composition. The process comprises heating an asphalt cut in a stirred tank to a temperature sufficient to allow the stirring of the asphalt in the tank. A thermoplastic elastomer or rubber is added to the asphalt while continuing to stir the asphalt. The mixture is stirred at a speed and for a period of time sufficient to increase the distribution of the elastomer into the asphalt. The stirring speed is reduced and the temperature is increased to add an oil dispersion or aqueous emulsion of crosslinking agents to the tank. Stirring is continued for a period of time sufficient to improve the distribution of the crosslinking agent dispersion in the asphalt.

摘要： A bipolar micro-power rail-to-rail operational amplifier has a low complexity output stage that provides a high ratio of load current to no load idle current. The output stage includes first and second output transistors of opposite conductivities whose current circuits are connected in series at the output terminal between high and low voltage supplies. A control transistor responds to the drive voltage at its base by modulating the base-emitter voltages of the first output transistor and a gain transistor in opposite directions to modulate their respective output and gain currents. A regenerative current source supplies current to the gain transistor by returning the gain current in a regenerative feedback loop to its emitter so that the current source idles at a low gain current but is capable of supplying much higher gain currents. A voltage element responds to the gain current by applying a control voltage to the base of the second output transistor so that the output transistors' output currents are unbalanced thereby generating an output current at the output terminal.

摘要： An apparatus and method is provided for dispensing coil emboli one at a time in a controlled and reliable manner during surgery to embolize several blood vessels or the like in a body. The apparatus includes a magazine that is movable within a dispenser housing to position each of the embolus cartridges contained in the magazine one at a time at a dispensing station on command. A stream of pressurized fluid is injected or a guide wire is inserted into the embolus cartridge held in the dispensing station to dislodge an embolus contained therein and discharge it into an embolus-delivery catheter coupled to the dispenser housing. Afterwards, the magazine is moved within the dispenser housing to remove the just-emptied embolus cartridge from the dispensing station and load a fresh embolus cartridge into the dispensing station.
