A static mixer or a flow reactor comprising a static mixer for mixing streams of fluid transported through or circulated in a flow reactor is provided. A static mixer element reduces the size of gas bubbles in a liquid for installation in a flow channel, and comprises, a first mixer unit and a second and adjacent mixer unit, which mixer units are displaced relative to each other in the flow direction, such that a through opening in the first mixer unit at least partly faces a surface of the second mixer unit thereby forcing the fluid flow to change direction. Adjacent mixer units have substantially the same height or thickness, and are substantially parallel having a distance between them that may be near zero or up to 10 times the thickness of a mixer unit.

A method of operating a dump tank of a polymer production process by transferring all or a portion of a content of a polymerization reactor into the dump tank, wherein the reactor contents comprise solid polymer, and liquid and gaseous non-product components, and removing at least a portion of the liquid and gaseous non-product components from the dump tank by: reducing a pressure of the dump tank, subjecting the solid polymer to a first cleaning stage comprising heating the solid polymer by introducing a first heated treatment gas into the dump tank, and subjecting the solid polymer to a second cleaning stage comprising purging the solid polymer by introducing a second heated treatment gas into the dump tank.

A process for continuous preparation of halogenated alkoxyethane of general formula XClHC—CF.sub.2OR, where X is —Cl or -f and OR is C.sub.1-4 alkoxy, the process comprising a step of introducing in a flow reactor reaction components comprising (i) a compound of general formula XClHC—CYF.sub.2, where each of X and Y is independently —Cl or —F, (ii) a base, and (iii) a C.sub.1-4 alkanol, wherein a) the flow reactor comprises one or more tubular flow line(s) through which the reaction components flow as a reaction mixture, c) the halogenated alkoxyethane is formed at least upon the reaction components mixing, with the so formed halogenated alkoxyethane flowing out of the flow reactor in a reactor effluent, and b) the base is one that forms a salt soluble in the alkanol during formation of the halogenated alkoxyethane.

Provided herein are methods and systems for at least partially deactivating at least one component of a reactor effluent from gas phase polyolefin polymerization processes utilizing at least one glycol.

A catalytic membrane composite that includes porous supported catalyst particles durably enmeshed in a porous fibrillated polymer membrane is provided. The porous fibrillated polymer membrane may be manipulated to take the form of a tube, disc, or diced tape and used in multiphase reaction systems. The supported catalyst particles are composed of at least one finely divided metal catalyst dispersed on a porous support substrate. High catalytic activity is gained by the effective fine dispersion of the finely divided metal catalyst such that the metal catalyst covers the support substrate and/or is interspersed in the pores of the support substrate. In some embodiments, the catalytic membrane composite may be introduced to a stirred tank autoclave reactor system, a continuous flow reactor system, or a Parr Shaker reaction system and used to effect the catalytic reaction.

The disclosure relates to a device for continuously producing qualitatively high-grade crystalline silicon carbide, in particular in the form of nanocrystalline fibre.

The present invention provides a system for the production of a radiopharmaceutical including a radiosynthesis apparatus and a disposable cassette. The system of the invention includes a device that enables a position on the cassette to be freed for inclusion of an additional reagent vial. With the system of the invention a broader range of radiochemical syntheses can be envisaged using the cassette.

The invention is concerned with the production of 1-hexene and octenes from ethene. 1-Butene is optionally also to be produced. The problem addressed by the present invention is that of developing a process for producing 1-hexene from ethene by MTHxE etherification to achieve better chemical utilization of the employed carbon atoms. This problem is solved by catalytic retrocleavage of MTHxE into the C.sub.6 olefins and the alcohol, reuse of the alcohol in the etherification and reaction of the obtained C.sub.6 olefins with ethene to afford C.sub.8 olefins. In this way the alcohol is not lost from the process but rather is internally recirculated as a derivatizing agent. The less attractive C.sub.6 olefins from the cleavage product are upgraded to octene with further ethene in order to provide a further commercial product.
