Dynamic Tubular Reactor

The Dynamic Tubular Reactor is a piece of equipment used for chemical reactions, featuring a unique structure and operational characteristics. It is particularly suited for continuous-flow reactions where solid precipitates are formed during the reaction process.  Reactants enter the tubular reactor at a constant flow rate from one end; as they flow through the pipe, chemical reactions take place, and the reaction products exit from the other end. Unlike conventional tubular reactors, the dynamic tubular reactor may induce dynamic changes in the reaction system through various means—such as adjusting flow rate, temperature, or pressure—or by employing special designs that generate periodic disturbances or oscillations within the fluid inside the tube, thereby enhancing the reaction process.

Plate-type Flow Photoreactor

The plate‑type flow photochemical reactor is a novel reaction device that integrates the structural design of plate reactors with continuous flow technology, while leveraging the principles of photochemistry. The following will explore its structure, operating principles, advantages, and applications. In a plate‑type flow photochemical reactor, light of a specific wavelength emitted by the light source is focused or uniformly distributed throughout the plate‑shaped microchannels via an optical system. Driven by a micro‑pump, the reactants enter the microchannels at a constant flow rate, forming a thin‑layer flow that significantly increases the contact area between the reactants, the photocatalyst, and the light. Reactant molecules excited by light come into contact with the catalyst within the channels, generating active intermediates such as free radicals and holes, which in turn trigger photochemical reactions including oxidation, reduction, or substitution.

Multifunctional Circulating Loop Injection Reactor

Multi‑functional 5L loop reactor, designed for 6 MPa and 150°C, is used in exploratory applications of chemical processes such as hydrogenation, oxidation, esterification, and polymerization. This unit employs process intensification technology, achieving micro‑ and nano‑scale gas–liquid mixing that delivers milk‑bath–like mixing performance, thereby significantly enhancing reaction efficiency.

Microfluidic Synthesizer

The YZFlab series from YanZheng Instruments is a line of miniature flow synthesis systems. This reactor system is widely applicable to flow synthesis reactions, offering a variety of interchangeable reactor modules—including fixed beds, fluidized beds, coiled tubes, microchannels, and photochemical reactors—providing a continuous flow chemistry platform that can seamlessly meet your specific needs. The series is available in both educational and industrial versions, delivering flexibility, precision, and high productivity. It is suitable for evaluating a wide range of reaction conditions, including catalyst screening, optimization and composition screening of multi‑component catalysts, reaction condition and process optimization, as well as catalyst lifetime studies. YanZheng’s integrated system leverages advanced technologies such as automated control and information processing, coupled with a streamlined materials research and development pipeline, significantly boosting research throughput while offering a more compact, more integrated, smarter, and more scalable solution compared to traditional reactors.

Adiabatic Reactor System

Dynamic Tubular Reactor

The dynamic tubular reactor utilizes the intense shear forces generated by high‑speed stirring to break up and thoroughly mix the materials flowing along the inner wall of the reactor, achieving efficient mixing and rapid reaction. It is suitable for reactions with viscosities ranging from 0 to 3000 cP, offering a broad application scope. Featuring a dual‑layer heat exchange design—where the central stirring system and the outer jacket work in tandem—the effective heat transfer area is increased fivefold. This reactor is applicable to homogeneous, heterogeneous, or multiphase reactions, effectively enhancing the reaction interface and promoting mass transfer. It is particularly well suited for reactions involving solids or slurries, enabling the production of solids with a uniform particle size distribution.

Dynamic Disc Reactor

The dynamic disc microreactor features a stator housing and one or more rotating discs, with a gap of 0.5 mm to 2 mm between the housing and the rotating discs. Thanks to the high-speed gradients generated by the rotating discs within this narrow gap, substantial shear forces can be imparted to the fluid flowing between the housing and the rotating disc surfaces, thereby enhancing heat and mass transfer while rapidly homogenizing concentration and temperature variations at the microscale. It is particularly well suited for gas–liquid, liquid–liquid, and solid–liquid reactions, and represents the first microreactor capable of accommodating solid-phase participation.
