The rapid-heating multi-field fixed-bed reactor aims to construct field-strengthened and flexibly coupled multi-field interactions. By altering catalytic reaction pathways in multiple dimensions—such as electronic-state regulation, reaction kinetics optimization, and mass-transport enhancement—it achieves a synergistic enhancement effect of “1+1>2”.
● Light utilization efficiency: increased by approximately 60% or more (compared with a top-illumination light-guide-column structure)
The top-illumination photothermal reactor has a light utilization efficiency of approximately 50%.
This reactor has a light utilization efficiency of approximately 80%.
Overall efficiency improved by approximately 60% or more.
● Electric-heat utilization efficiency: increased by approximately 3 times or more (compared with conventional tubular furnace systems)
A tubular heating furnace requires about 130–150 W to maintain 500℃ under no-load conditions.
This reactor requires about 40 W to maintain 500℃ under no-load test conditions.
Overall electrical energy utilization can be improved by about three times or more.
● Experimental time efficiency: increased by several times or more (compared with traditional fixed-bed systems)
Conventional fixed-bed systems are time-consuming due to slow heating/cooling balance; temperature adjustments or catalyst screening take time, and cooling typically requires next-day operations.
This reactor heats and cools rapidly, with thermal equilibrium reached in about 15 minutes, allowing up to 8 or more samples per day.
Overall time efficiency can be improved by several times or more.
Enables single-wavelength, high-energy-density photothermal coupled catalytic reactions;
Implements coupling strategies between microwave fields and catalysts (e.g., heterojunction catalyst design) and has developed an integrated multi-field reactor combining light, heat, and microwaves;
Developed solutions for hard-to-degrade problems in industrial waste gas and chemical exhaust streams.
● Feature 1: Multi-energy-field coupling
Light field, resistive heating field, microwave field—study catalytic reactions under different individual or synergistic fields, such as light–heat coupling, light–microwave coupling, and light–heat–microwave multi-field coupling.
● Feature 2: Rapid-heating characteristics
① Resistive heating temperature rise rate: ≈100℃/min; ② Microwave heating temperature rise rate: ≈40–50℃/min; ③ Light-source heating temperature rise rate: ≈20℃/min;
High experimental efficiency and suitability for fast-heating reaction requirements.
● Feature 3: Fast response
① Fast thermal equilibrium (~15 min), improving heating-balance time by over ~3× compared with traditional heating; ② The reaction zone has a small void volume with almost no dead volume, enabling efficient gas exchange and very short reaction response times (on the order of seconds), showing significant improvement over conventional tubular reactors.
● Feature 4: High efficiency and energy saving
Light source: annular-illumination design places the light source close to the reactor, minimizing optical path loss; the reactor includes an internal reflective layer to improve secondary utilization of reflected light.
Resistive heating: ① Built-in heating elements with catalyst in close contact with the heater to effectively reduce conductive heat loss; ② Vacuum insulation layer design reduces air thermal conductivity (heat-conduction coefficient less than 1/100 of that at atmospheric pressure); ③ Reactor internal reflective layer enables secondary utilization of thermal infrared; compared with traditional reaction furnaces, maintenance energy consumption is reduced by over three times.
● Feature 5: Light energy utilization
① Single-wavelength LED source enables precise light control, matching catalyst bandgaps, avoiding multi-wavelength interference, and improving quantum efficiency.
② The irradiated area is greatly increased and monochromatic light power density is relatively high; the catalyst surface can reach up to roughly 32 suns. Effective illuminated area ranges from 3.14 cm2 (bed height 10 mm) to 15.7 cm2 (bed height 50 mm), with a maximum illuminated area of about 31.4 cm2. For example, the HL100-365 light source has a light power density >3.2 W/cm2 (measured without mesh shielding).
