Abstract: The invention concerns a microreactor for carrying out chemical reactions between a reaction partner in liquid form and a reaction partner in gaseous form, if necessary in the presence of a solid catalyst, whereby the chemical process guidance takes place in spaces that are formed by two or more essentially coplanar plates or layers, with at least one of these plates or layers being a fluid guidance plate (1) that is structured and/or arranged in such a way that the fluid reaction partner flows in at least one essentially uninterrupted capillary thread along the surface of this plate or layer only due to the influence of gravity and/or capillary forces and thereby comes into contact and reacts with the gaseous reaction partner.

Abstract: The present invention comprises a mixing system that provides improved mixing of quench gas and process fluids in a height constrained interbed space while not increasing pressure drop. In particular, the device improves the effectiveness of an existing mixing volume in mixing the gas phase of two-phase systems. The mixing system includes a horizontal collection tray, a mixing chamber positioned below the collection tray, at least one passageway extending through the collection tray into the mixing chamber, and a vapor slipstream passageway extending through the collection tray into the mixing chamber for directing a vapor slipstream from above the collection tray into the mixing chamber. The mixing chamber and the collection tray define a two-phase mixing volume. The passageway conducts fluid containing at least some vapor from above the collection tray into the mixing chamber. The mixing chamber preferably includes at least one outlet opening for the downward passage of fluid. The vapor slipstream passageway, optionally, comprises a plurality of inlets arranged to impart rotational movement to the vapor phase at a location within the mixing chamber where the vapor phase has substantially expended the kinetic energy of its initial entry into the mixing chamber. As a result of providing at least one additional passageway for a vapor slipstream, and optionally, including one or more baffles as described above, significant re-acceleration of the vapor phase is achieved in the mixing chamber resulting in improvements in mixing efficiency of both the vapor and liquid phases.

Abstract: A device and method for separating water into hydrogen and oxygen is disclosed. A first substantially gas impervious solid electron-conducting membrane for selectively passing protons or hydrogen is provided and spaced from a second substantially gas impervious solid electron-conducting membrane for selectively passing oxygen. When steam is passed between the two membranes at dissociation temperatures the hydrogen from the dissociation of steam selectively and continuously passes through the first membrane and oxygen selectively and continuously passes through the second membrane, thereby continuously driving the dissociation of steam producing hydrogen and oxygen. The oxygen is thereafter reacted with methane to produce syngas which optimally may be reacted in a water gas shift reaction to produce CO2 and H2.

Abstract: For the selective production of propylene from an olefinic C4 fraction, a process is implemented that successively comprises: 1) the selective hydrogenation of butadiene with isomerization of butene-1 into butene-2; 2) the separation by distillation of a mixture that is rich in isobutene and butene-1 at the top and a fraction that is rich in butene-2 at the bottom; 3) the skeletal isomerization of isobutene into n-butenes on the top fraction, with recycling in stage 1; and 4) the metathesis of the butene-2-rich fraction with ethylene. The advantage of this process is to produce in a very selective way polymerization-quality propylene from all of the olefinic compounds of a C4 fraction, including isobutene.

Abstract: The invention concerns a method and an installation for purifying impure helium. Said method consists in subjecting the helium to at least two successive steps: (a) cryogenic refrigeration of impure helium so as to eliminate by condensation at least part of the main impurities it contains and recuperating helium with intermediate purity containing residual impurities; and (b) permeation of at least part of the helium with intermediate purity derived form step (a) so as to eliminate at least part of said residual impurities and recuperating helium with final purity higher than said intermediate purity. Said method and said installation are useful for purifying impure helium recuperated at the output of an optical fibre cooling chamber, prior to the reintroduction of the resulting purified helium into said chamber so as to recycle the helium.

Abstract: Carbon monoxide in reformate gas is removed by oxidizing reactions in a plurality of catalytic components (4A-4C) disposed in series. Air from air supply valves (6A-6C) is supplied to the catalytic components (4A-4C). The oxidation amount of carbon monoxide in the catalytic components (4A-4C) depends on air supply flow rates of the air supply valves (6A-6C). A controller (7) controls the air supply valves (6A-6C) so that the ratio of the air supply flow rate to an upstream component (4A) with respect to the air supply flow rate to a downstream component (4C) decreases as a flow rate of reformate gas decreases. In this manner, reverse shift reactions generating carbon monoxide as a result of reactions between carbon dioxide and hydrogen contained in the reformate gas can be suppressed in the downstream catalytic component (4C) when the flow rate of reformate gas is low.

Abstract: A reactor system 10 for use in chemical processing. The system 10 includes a reactor 12 having a longitudinal cylindrical bore 14 and a basket assembly 18 that is received in the bore so that the basket assembly is secured in relation thereto. The basket assembly includes an inner, generally cylindrical basket 20 and an outer, generally cylindrical basket 22 that is coaxial with the inner basket. The inner and outer baskets define an annular space 24 therebetween, the annular space being adapted to accommodate a granular catalyst 26. A rotatable shaft assembly 28 extends axially within the bore. The shaft assembly includes an upper end 30, a lower end 32 and a central section 34 extending therebetween. The upper and lower ends each have a pump 36,38 for directing flow of a chemical reagent 40 axially toward the central section upon rotation of the shaft assembly. The central section 34 is provided radially with extending blades 42 for urging flow of the reagent outwardly through the annular space between the baskets. The reactor system 10 promotes flow and mixing between the chemical reagent and the catalyst, thereby enhancing the kinetics of chemical reaction, control, and the reproducibility thereof.

Abstract: The present invention is directed to a novel high temperature polymerization process operating at high pressures for producing a polymer. The process includes conveying hybrid reactor mixtures, which include one or more hybrid reactor monomers and one or more hybrid reactor initiators to one or more hybrid reactors. The hybrid reactors are maintained at effective hybrid polymerization temperatures and sub-reflux polymerization gage pressures to cause polymerization of a portion of the hybrid reactor monomers into the polymer. The process further includes conveying hybrid reactor contents from. the hybrid reactors to one or more batch reactors maintained at effective batch polymerization temperatures and reflux polymerization pressures to cause polymerization of a remaining portion of the hybrid reactor monomers into the polymer. The hybrid reactors are smaller in volume than the batch reactors. By utilizing the hybrid/batch reactor combination, the process of the present invention can be operated under safe working conditions. The process of the present invention also allows control of the polydispersity and molecular weight of the resulting polymers. As a result, the polymers made therefrom can be used as binders in compositions, such as coating compositions used in the automotive refinish and OEM applications having desired coating properties. The present invention is also directed to a polymerization system used in the process of the present invention.
