The present disclosure relates to catalytic static mixers comprising catalytic material. The static mixers can be configured for use with continuous flow chemical reactors, for example tubular continuous flow chemical reactors for heterogeneous catalysis reactions. This disclosure also relates to processes for preparing static mixers. This disclosure also relates to continuous flow chemical reactors comprising the static mixers, systems comprising the continuous flow chemical reactors, processes for synthesising products using the continuous flow reactors, and methods for screening catalytic materials using the static mixers.

A system for continuously treating recycled polymeric material includes a hopper configured to feed the recycled polymeric material into the system. An extruder can turn the recycled polymeric material in a molten material. In some embodiments, the extruder uses thermal fluids, electric heaters, and/or a separate heater. The molten material is depolymerized in a reactor. In some embodiments, a catalyst is used to aid in depolymerizing the material. In certain embodiments, the catalyst is contained in a permeable container. The depolymerized molten material can then be cooled via a heat exchanger. In some embodiments, multiple reactors are used. In certain embodiments, these reactors are connected in series. In some embodiments, the reactor(s) contain removable static mixer(s) and/or removable annular inserts.

A tubular flow module includes at least two concentric tubes with spiral features, wherein first tube is coaxially arranged inside a second tube and each tube has a maximum diameter and a minimum diameter, wherein the maximum diameter of first tube is larger than the minimum diameter of second tube, defining a flow path for fluids between first and second tubes. A tubular flow module system and use of the tubular flow module is also disclosed.

A fluid mixer for a reactor of a hydrocarbon processing plant includes a substantially cylindrical mixing chamber, at least one first inlet for conducting first fluid to the mixing chamber from above the mixing chamber and along a side wall of the mixing chamber to produce a spiral stream in the mixing chamber, at least one second inlet for conducting second fluid tangentially into the spiral stream, and an outlet channel for conducting the first and second fluids downwards out from the mixing chamber. The outlet channel is concentric to the mixing chamber and includes a mixing structure for enhancing mixing of the first and second fluids. At least a part of the mixing structure is located below an upper edge of the outlet channel and produces turbulence in a stream of the first and second fluids flowing in the outlet channel.

In at least one embodiment, a reactor includes a reactor body. A first internal heat exchanger and a second internal heat exchanger are within the reactor body. One or more slabs of one or more static inserts are disposed between the first internal heat exchanger and the second internal heat exchanger. A plurality of flow paths is defined between the plurality of flow channels of the first internal heat exchanger and the plurality of flow channels of the second internal heat exchanger. Each static insert is configured to rotate or translate a flow path so that on average, the existing boundary layers formed in the first heat exchanger are moved away from the channel walls by a distance of equal or greater than the thickness of the boundary layers at the exit of the first heat exchanger.

The present invention relates to multi-bed catalytic reactor with a cylindrical shape comprising a mixing device mounted between two catalyst beds in the reactor, said mixing device comprises connected pipe segments forming mixing section and discharging section.

Described herein are methods for the continuous preparation of 1,2-di(furan-2-yl)ethane-1,2-diol from furan-2-carbaldehyde. The methods can proceed chemically or electrochemically. In certain examples, the methods further comprise the application of a static mixer. The present methods produce 1,2-di(furan-2-yl)ethane-1,2-diol in greater yield, purity, chemoselectivity, and stereoselectivity than traditional batch methods.
