In heterogeneous catalytic research, the micro fixed-bed flow reactor has long been a cornerstone for exploring the mysteries of matter transformation. However, as exploration in the energy and chemical fields moves into frontier areas such as photothermal catalysis and microwave-assisted catalysis, traditional experimental equipment is gradually showing its limitations:
• Slow heating and low efficiency: Traditional furnace heating has high thermal inertia. Heating and cooling operate at a “turtle’s pace,” often costing half a day just to complete a temperature-programmed experiment.
• Non-uniform light field: Common “furnace-wall aperture” illumination introduces light like “peering at a leopard through a tube.” Only the focal spot is illuminated—some catalyst areas are over-lit while others receive none. Photothermal synergy is suppressed, and decoupling is nearly impossible.
• Delayed heat transfer: External heating results in severe temperature gradients. The temperature you measure—does it really represent the catalyst surface reaction temperature?
What kind of scientific sparks would fly if rapid temperature switching, full-dimensional illumination, and microwave fields could all be integrated into a single device?
PorphyreTech proudly launches the Rapid-Heating Multiphysics Fixed-Bed Reactor. This is not just an equipment upgrade—it is an elevation of the dimensionality of mechanism exploration!

[Traditional Pain Points]: A conventional tube furnace is like a giant “thermos,” heating by warming the surrounding air through resistance wires. Large thermal inertia and slow response, and the reactor wall is often hotter than the catalyst bed center—easily causing side reactions or coking.
[PorphyreTech’s Innovative Solution]: Internal-Heating Reaction System
The Joule-heating technology shown in the video heats directly with the heater in intimate contact with the catalyst.
• 300°C in 5 minutes: Achieving true inside-out rapid heating.
• Energy management: Combined with a high-vacuum jacket that blocks outward heat loss, ensuring every joule of heat is used for reaction. The infrared reflective layer redirects radiative heat back into the reactor—locking the heat inside.
• Scientific value: Such rapid heating enables research on non-steady-state catalysis and temperature-pulse reactions, significantly shortening catalyst screening and lifetime testing cycles.
[Traditional Pain Points]: Many photothermal fixed-bed reactors simply “borrow light” by drilling holes in furnaces. Light enters unidirectionally, illumination is limited, and reactor walls cause severe light attenuation.
[PorphyreTech’s Innovative Solution]: Tri-Sided Surround LED Illumination
The device adopts modular, user-replaceable LED units arranged in a three-sided surrounding layout.
• 360° coverage: Uniform rectangular illumination over the catalyst bed eliminates “bright and dark sides.”
• Ultra-high photon flux: Reaching intensities equivalent to over 30 suns, while vacuum insulation blocks heat interference from the light source.
• Scientific value: Enables true photothermal decoupling—you can accurately calculate photon efficiency and distinguish whether performance enhancement originates from photogenerated carriers or pure thermal effects. This directly addresses the core of the academic debate on photothermal synergism.
[Frontier Trend]: Microwave chemistry, due to its unique “non-thermal effects” and “selective heating,” is rapidly emerging in plastic degradation, biomass conversion, and rapid synthesis.
[PorphyreTech’s Innovative Solution]: Efficient and Safe Microwave Injection
This is not only a photothermal reactor—it is also a microwave reaction station.
• Four needle-type microwave feeds: Ensuring efficient and uniform microwave energy delivery.
• Safety shielding: Reactor, viewports, and light-entry windows are equipped with shielding meshes to ensure operational safety.
• Scientific value: Microwaves penetrate catalyst supports and directly interact with active sites (e.g., metal nanoparticles), forming microscopic “hot spots.” This device enables microwave-effect studies under flow conditions, offering new possibilities for developing efficient chemical processes at low temperature and pressure.
The soul of this device lies in the independent control and seamless coupling of the thermal, light, and microwave fields.
• Heat only: Rapid heating for efficient screening.
• Light + Heat: Simulating concentrated sunlight heating, ideal for tackling endothermic reactions such as CO₂ hydrogenation and methane reforming.
• Microwave + Heat: Using microwaves to reduce activation energy.
• Light + Microwave: Exploring the rarely studied mechanism of dual-field coupling.
From “follower” to “leader,” imagination alone is not enough—you need stronger hardware to unleash it.
