Abstract: The present invention relates to an apparatus for producing alcohols from olefins, comprising: a hydroformylation reactor wherein aldehydes are produced from olefins; a catalyst/aldehydes separator; a hydrogenation reactor wherein the aldehydes are hydrogenated to produce alcohols; and a distillation column. The hydroformylation reactor is equipped with a distributor plate, which has a broad contact surface for providing sufficient reaction area for reactants such as olefins and synthesis gas, and allows the reaction mixture to circulate and mix sufficiently, which contribute to excellent efficiency in terms of production of aldehydes. In addition, the hydrogenation reactor suppresses sub-reactions to improve the production yield of alcohols.

Abstract: A microfluidic manipulation system is provided that includes a blade for manipulating deformable material and at least one movable support that is capable of moving the blade into contact with a microfluidic device including a deformable feature. When the microfluidic device is operatively held by a holder, a movable support can position the distal end of the blade relative to the microfluidic device and move the contact tip surface of the blade such that it deforms the deformable feature.

Abstract: A distributor nozzle for a two-phase charge, to be used in fixed-bed reactors in order to increase the area over which the mixture is dispersed and to make its flow rate the same over the whole area of the bed in the reactor. The device includes a number of fixing bars and a deflector cone frustum. The deflector cones or cone frusta may have more than one angle in order to improve the distribution, and they have a number of apertures or slits and a number of vertical directing elements or a directing cage or frame to direct the stream of the two-phase charge in order to increase the area over which the mixture is dispersed and to make its flow rate the same over the entire area of the bed in the reactor.

Abstract: The invention is a fluid distribution device for coupling with a fluid distribution conduit or chimney for improving the distribution of downwardly flowing poly-phase mixture including at least one gas phase and at least one liquid phase, above at least one catalyst bed of granular solid catalytic material. The fluid distribution device for receiving the liquid and gas phases has one or more openings in the top and/or upper portion of its height through which a gas phase can enter and has a gas conduit that opens to a mixing cavity within the device. The fluid distribution device further comprises one or more lateral openings for liquid ingress. The lateral opening or openings allow the liquid to enter a liquid conduit that opens to the internal mixing cavity. The mixing cavity allows intimate contact between the liquid and gas phases. Therefore the flow distribution device of the invention provides improved tolerance for tray out of levelness.
