The system comprises a liquid feed control module, a preheater module, a reactor module, a condensation module, a gas–liquid separation module, a liquid sampling module, and a reaction pressure control system that offers users flexibility in selecting the phase state of their feedstock—either two liquid streams or a combination thereof. The flow rate of each gas fed into the reactor is precisely controlled by a high‑precision piston metering pump.

Electrode Fixed Bed

The electrode-fixed bed is a technological device that combines the effects of an electric field with a fixed-bed structure, and it finds important applications in a variety of fields—including environmental engineering, bioengineering, and chemical production. Like traditional fixed beds, it consists of a vessel filled with solid particles. These solid particles typically exhibit a certain particle size distribution and pore structure, offering a large specific surface area that provides a suitable environment for various physical and chemical processes. For example, in catalytic reactions, the solid particles may serve as supports loaded with catalysts; in adsorption processes, the particles may be adsorbents such as activated carbon.

Microbubble Fixed Bed

Microbubble process intensification in fixed beds is a technological approach with significant applications in fields such as chemical engineering and environmental science. By employing specialized equipment or methods, gas is dispersed into tiny bubbles, typically on the micrometer scale. These microbubbles possess a large specific surface area, providing an increased gas–liquid interfacial area. This dramatically enhances gas–liquid mass transfer efficiency; for processes that are mass-transfer–limited—such as gas absorption and liquid-phase oxidation—it can significantly accelerate reaction rates and improve production efficiency. Moreover, due to the enhanced mass transfer efficiency, the volume of fixed bed required for processing the same amount of material is relatively small, resulting in a compact footprint for the equipment and facilitating plant layout and construction.

Fully Automatic Hydrogenation Instrument

Fully automatic hydrogenation system, designed for a maximum temperature of 500°C and a maximum pressure of 20 MPa. The feed system is equipped with a weight‑based closed‑loop control module to optimize and ensure precise high‑pressure HPLC sample delivery. The system’s total volume is less than 100 ml, enabling safe hydrogenation. The discharge section features a 1 ml quantitative loop for collecting fresh samples, while the gas–liquid separation volume module is designed to be less than 10 ml. Coupled with an automatic drain valve, this configuration achieves pressure‑stable, high‑pressure automated discharge without pressure fluctuations. The system’s pressure is automatically controlled, and the entire system is equipped with sequential control workflow software, enabling fully automated process operation around the clock with no human supervision.

It is constructed from quartz and 316L 625 reactor materials, with the entire system undergoing passivation treatment. Three-stage condensation ensures automatic discharge of condensates (wax, water, gasoline) without pressure fluctuations, while pressure is automatically controlled. The system features robust safety protection mechanisms at the hardware level, including safety relief valves, to ensure safe operation even in the event of emergencies such as power outages or gas supply interruptions.

Scalable Agitated Baffle Reactor

The Scalable Agitated Baffle Reactor is a scalable stirred baffle reactor capable of performing continuous stirred-tank reactors (CSTRs). The scalable agitated baffle reactor is ideal for laboratory use within flow chemistry technology platforms—it’s a scalable stirred baffle reactor designed for continuous stirred-tank operation (CSTR). It can be used for continuous reactions involving liquids, gases, and solids, and is widely applied in fields such as fragrances, food supplements, cosmetics, and pharmaceutical intermediates. By combining the advantages of batch reactors and continuous flow reactors, it is suitable for a wide range of applications and can be easily scaled up. With its high performance, it delivers superior product quality, accelerates development timelines, and boosts production output.

3-Reactort Continuous Stirred-Tank Reactor

3. A two‑reactor continuous CSTR (Continuous Stirred Tank Reactor) is a reaction system composed of two continuously stirred tank reactors connected in series, commonly used in chemical reaction processes in fields such as chemical engineering. It is widely applied in petrochemicals, fine chemicals, and other related industries. For example, in the synthesis of ethyl acetate, a two‑reactor continuous CSTR can be employed: acetic acid and ethanol undergo an initial reaction in the first reactor under sulfuric acid catalysis, followed by a subsequent step in the second reactor to further increase the conversion rate. In polymerization reactions, it can also be used to produce high‑molecular‑weight materials such as polyvinyl chloride, where different reaction conditions in the two reactors are utilized to control the molecular weight and structure of the polymer.

Gradient‑Free/Hypergravity Reactor

Synthetic gas to methanol non-gradient reaction system, designed for a pressure of 15 MPa and a temperature of 350°C, with a rotational speed of 2000 rpm. It is equipped with two inlet lines and a vapor-phase condensation backpressure control module. The system supports digital display of pressure readings and allows free switching between multiple pressure units; it offers both insulation timing and start-up timing in dual‑timing mode; it features a remote control interface with an RS485 communication port; remote control via a mobile app is supported, along with safety interlock functions and over‑temperature/over‑pressure alarms. The system boasts a compact structure and convenient operation.

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.
