What is the Johnson Screen Catalyst Support Grid?
The Johnson screen catalyst support grid is made of stainless steel wedge wires allowing for the optimal placement and retention of catalysts. Its unique design features slotted openings, which are specifically engineered to facilitate the uniform flow of fluids while supporting the catalyst bed in vessel internals.

As the catalyst support screen, the grid acts as a filtration and distribution system, helping to ensure that the catalyst remains in place and operates at peak efficiency. This is crucial in catalytic reactions, where even slight disruptions in catalyst support can significantly impact the overall process and product yield.

▪ Wedge Wire Design
Johnson Vee wire technology creates consistent slot openings and uniform flow distribution. This results in a stable and efficient catalyst bed that maximizes the performance of the reactor.

▪ High Strength and Durability
High-quality stainless steel 304, 316 material is resistant to corrosion, high temperatures, and harsh chemical environments. The support grid is ideal for chemical reactors and other industrial applications where durability is crucial for long-term performance.

▪ Superior Filtration and Flow Distribution
The wedge wire design provides excellent filtration capabilities, ensuring that catalyst particles remain intact while allowing fluids and gases to flow freely through the system. This improves both reaction efficiency and product quality.

▪ Customizable to Reactor Needs
The Johnson Screen Catalyst Support Grid is highly customizable to meet specific reactor internal requirements. The design can be tailored to various sizes, shapes, and slot configurations, ensuring a perfect fit for reactors and catalytic processes.

▪ Enhanced Reactor Performance
The wedge wire support grid acts as a uniform catalyst bed to effectively prevent catalyst movement or fouling, helping to improve the overall performance of the catalytic process.

Applications of the Johnson Screen Catalyst Support Grid
▪ Petrochemical Industry: For refining processes where catalysts play a key role in reactions such as cracking, hydroprocessing, and reforming.
▪ Natural Gas Processing: In reactors used for methane reforming, sulfur recovery, and other gas processing applications.
▪ Chemical Manufacturing: Used in various chemical reactor internals
▪ Refining Industry: For hydrocracking and other refining processes where catalyst support grids are critical for maintaining stable catalyst beds.

Common Problems
※ The support beams of the catalyst bed support grid are heavy, which can easily cause the grid to deform.
※ There is a gap between the support beams and the support grid, which can easily cause poor ventilation.

Tips: To avoid common problems, you need to provide the supplier with specific specifications and data on the product environment before purchasing.
