Driven by the "dual carbon" goal, the high-value conversion of biomass resources has become an important research direction in the energy and chemical industry. Whether it is the production of high-quality bio-oil from biomass pyrolysis or the catalytic reforming and upgrading of pyrolysis volatiles, the fixed-bed reactor is one of the most crucial pieces of equipment. However, many research groups encounter numerous difficulties in practical operation.

• Slow heating: Traditional heating methods cannot reach extremely high heating rates, missing the true kinetic window.
• Difficult integration: Existing fixed-bed devices are difficult to integrate with light source introduction.
• Low efficiency: Single channel, single sample; catalyst screening and operating condition optimization are time-consuming.
• Disjointed pyrolysis and upgrading processes, making it difficult to conduct parameter matching studies for series operation.
These pain points are precisely the design starting point for the PLR RVTF-PH biomass pyrolysis upgrading device.

PLR The RVTF-PH biomass pyrolysis upgrading device is a multifunctional experimental platform integrating a gas distribution system, preheating system, light source and reaction system (photothermal reaction/thermal reaction/biomass pyrolysis), condensation and separation gas system, and back pressure control system. It is centrally controlled via PLC programming and a high-definition touchscreen. The core processes of this device cover key aspects of biomass pyrolysis upgrading research—from rapid pyrolysis of biomass feedstock to catalytic reforming and upgrading of pyrolysis volatiles, and finally to product condensation and separation, all within a single platform. Applicable scenarios include gas-solid phase continuous flow fixed-bed photo/thermal reactions, and biomass pyrolysis upgrading and related fixed-bed catalytic reactions.

1. Three Major Reaction System Modules
PLR The RVTF-PH biomass pyrolysis and upgrading device consists of three main reaction system modules: a photothermal system, a thermal reforming system, and a biomass dry distillation system. The possible process routes include: **Independent Photothermal System:** Reactants enter the photothermal chamber for photothermal reaction; **Independent Biomass Dry Distillation System:** Reactants enter the dry distillation pyrolysis system, where a sliding rail heating module achieves rapid sample heating and pyrolysis; **Biomass Dry Distillation System-Thermal Reforming System in Series:** Pyrolysis products then enter the reforming module. Each module can be selected according to the corresponding process route based on research needs.
2. Sliding Rail Heating Module
The device is equipped with a sliding rail dry distillation furnace, which enables rapid heating and decomposition of biomass. Researchers can truly conduct rapid pyrolysis kinetic studies—rapidly pushing samples into the predetermined temperature zone, shortening the transition time during heating, thereby obtaining more realistic kinetic parameters and product distribution data.
For rapid biomass pyrolysis research, the heating rate directly determines the volatile matter release behavior and product selectivity. The sliding rail design makes this key variable controllable and repeatable.


3. Dual Sample Zone
The dual sample zone allows for the sequential completion of experiments on two sets of materials under the same temperature and atmosphere conditions after a single loading. For catalyst screening and condition control experiments, this design reduces the need for intermediate disassembly and reheating.
4. Three Independent Temperature Zones + Cascade Operation The device integrates three independent temperature zones: **Dry Distillation Chamber (180~900℃):** A sliding rail-type rapid pyrolysis zone equipped with a quartz boat (20 mL × 2, volume can be customized); **Photothermal Chamber (180~800℃):** Used for photothermal catalytic reactions; **Reforming Chamber (180~800℃):** Used for catalytic reforming and upgrading of pyrolysis volatiles. Each of the three zones can be programmed with 16 temperature increments. You can complete the entire process of "rapid pyrolysis → thermal reforming → product condensation and separation" in one unit, achieving systematic matching of pyrolysis-reforming upgrading process conditions.



5. PLC + Touch Screen Control
The entire system is controlled by PLC programming and equipped with a high-definition touch screen. The reaction system supports multi-segment temperature rise and is easy to operate. WiFi connection is supported by default, enabling remote program maintenance and upgrades.
