Multi-Functional Desktop Fixed-Bed Reactor
Desktop fixed-bed is a multi-functional desktop fixed-bed integrating manual control and automatic control. It has a small dead volume and can realize precise control of experiment condition, so as to ensure experiment reproducibility and sensitivity. Adopting distributed control system solution, the device is highly stable and safe. Moreover, the device adopts modular design concept. After a simple expansion or upgrade, it can be used in fields such as catalyst evaluation and membrane performance, and it is well suited to research of dynamics of continuous flow reaction, exploration of reaction conditions and optimization of technological conditions.
Advantages and characteristics
⚫ Modular design: Modular selection and design for materials, equipment, instruments, processes, analytical instruments (such as GC and conductivity meter) can be carried out based on users’ actual requirements for flow control, temperature, pressure, corrosion and degree of automation, etc.
⚫ Integrated manual control and automatic control: Germany Siemens PLC module and 10.2-inch MCGS touch screen are adopted for the hardware control system. The in-depth customization and development of operating system makes the operation easier. The DCS interface shall include the display and control screens of process, flow and temperature and data trend chart, etc.
⚫ Multi-safety protection: The range of parameters of the operating system can be set to prevent the misinput of parameters; When the pressure or temperature exceeds the limit, the control system will automatically activate relevant protection measures and send a prompting message to the user for handling. Safety valves are installed to prevent system over-pressure

Design principle of custom continuous flow reactor/ catalyst evaluation unit:
1. Learn about basic requirements of the customer and relevant key parameters and develop the preliminary design scheme
2. Discuss the scheme with the customer and identify the risk points
3. Amend the scheme until it is approved by the customer and create an order
Note: The customer enjoys the right of final decision of the scheme. We will give the customer corresponding advice based on ours experience and cases
