The HTVB-50 is a compact high-temperature vibratory ball milling reactor designed for mechanochemical processing, catalyst activation, powder mixing, and materials research under controlled gas atmospheres. Integrating a heated reaction chamber with an adjustable vibration system, the equipment allows researchers to investigate the effects of mechanical energy, temperature, and gas atmosphere on material behavior and chemical reactions.

The reactor can operate at temperatures up to 500°C with programmable temperature control and a stated control accuracy of approximately ±1°C. Its standard configuration supports a maximum working pressure of 3 bar at 500°C, providing a controlled environment for selected high-temperature gas-solid reaction and catalyst research applications.

The stainless steel reaction chamber is manufactured from SS304 stainless steel and incorporates dedicated gas inlet and outlet connections with valves. An external heating ring surrounds the reaction chamber, while a vibration stage driven by a 24V DC motor provides adjustable mechanical excitation. The vibration motor speed can be adjusted from 400 to 2000 RPM, corresponding to approximately 6–33 Hz.

A separate control unit regulates the reactor temperature and vibration speed, allowing operators to configure the required processing conditions. Optional higher-pressure reactor configurations may be available for applications requiring different temperature and pressure combinations, subject to equipment design and verification.

The HTVB-50 is particularly suitable for mechanochemical activation of catalysts for CO₂ methanation research, gas-solid reaction studies, thermal-mechanical powder processing, and advanced catalyst development. It provides a laboratory platform for investigating reaction conditions and material transformations; actual CO₂ conversion and methane production depend on the catalyst, reactant composition, operating conditions, and experimental setup.

• Research Applications: Suitable for catalyst activation, CO₂ methanation studies, gas-solid reactions, and advanced mechanochemical materials research.

The HTVB-50 is available with different temperature and pressure capabilities depending on the selected reactor configuration. Each configuration has its own permitted operating limits and should be selected according to the intended experimental conditions.

Pressure Rating Note: These are separate temperature-pressure ratings for different reactor configurations. A 20 bar rating must not be interpreted as permitting operation at 500°C. Confirm the pressure reference basis, allowable gases, complete pressure-temperature limits, and pressure safety documentation before use.

The HTVB-50 incorporates a stainless steel reaction vessel with integrated gas delivery connections, allowing compatible process gases to be introduced and discharged under controlled experimental conditions. Its heated chamber and adjustable vibration stage support investigations involving mechanical activation, thermal treatment, and selected gas-solid chemical reactions.

The reaction chamber includes 1/8-inch inlet and outlet connections equipped with valves. A thermocouple feedthrough is provided on the flange for compatible temperature measurement arrangements. The external heating ring surrounds the reactor to transfer heat to the reaction chamber while the vibration stage applies mechanical excitation during processing.

Gas compatibility, reactor sealing, operating pressure, temperature limits, exhaust treatment, and the suitability of any hydrogen-containing atmosphere must be assessed for each application. The system requires appropriate gas pressure control and suitable laboratory safety infrastructure.

Carbon dioxide methanation is a catalytic reaction in which CO₂ reacts with hydrogen to form methane and water under suitable reaction conditions. Mechanochemical processing can be investigated as a method of modifying catalyst properties, promoting material contact, and studying the effects of mechanical energy on catalyst preparation and activation.

The HTVB-50 combines elevated-temperature operation, controlled gas delivery, and adjustable vibration in a compact experimental platform. Researchers may use this arrangement to evaluate how processing temperature, gas atmosphere, vibration conditions, milling media, and catalyst composition influence material behavior and reaction performance.

The equipment is intended as a research platform rather than a guaranteed methane-production system. Methane formation, CO₂ conversion, selectivity, and catalyst performance must be established through independently validated experiments using appropriately designed gas-handling, analytical, and safety systems.

The HTVB-50 consists of a heated vibratory reactor assembly and a separate control system. The referenced equipment configuration includes stainless steel milling media, while certain sensors, replacement sealing components, and specialized accessories may require separate selection.

Package Note: The standard package and optional accessory availability should be confirmed in the final PENGXIN Machinery quotation. Gas regulators, pressure-relief devices, thermocouples, gas analysis equipment, and other required safety components must not be assumed included unless specifically stated.

The HTVB-50 is designed for researchers investigating the combined effects of temperature, controlled gas environments, and mechanical vibration on catalysts and solid materials. Typical research applications include:

• Mechanochemical activation of catalysts for CO₂ methanation research
• High-temperature catalyst preparation and material treatment

• Investigation of mechanical energy effects on catalyst properties
• Advanced functional materials and chemical reaction research
• Laboratory-scale catalytic process development
• University, research institute, and industrial R&D applications

• Temperature and Pressure Limits: Never exceed the approved temperature-pressure rating of the selected reactor configuration. Optional higher-pressure ratings apply only at their specified lower temperatures.
• Gas Pressure Regulation: Use a suitable two-stage gas regulator and appropriate independent overpressure protection. Cylinder pressure must not be applied directly to the reactor.
• Hydrogen and Methane Safety: Hydrogen-containing experiments and methane-producing reactions present fire, explosion, and gas-leak hazards. Such experiments require trained personnel, appropriate gas detection, ventilation, exhaust handling, and a documented risk assessment.
• Gas Flow Control: Maintain gas delivery within the specified flow limit and ensure the complete gas-handling system is compatible with the intended process.
• Gas Leakage Prevention: Check reactor seals, flange connections, valves, and gas fittings using an approved leak-testing procedure before operation.

• Electrical Safety: Verify the local supply voltage, grounding, electrical protection, and controller connections before operation.
• Qualified Operation: Use the equipment only under an approved laboratory operating procedure with suitable process monitoring, emergency controls, and relevant safety documentation.

Configuration & Performance Note: The HTVB-50 is a laboratory research reactor. Maximum temperature, working pressure, allowable gases, loading capacity, accessories, and certification documentation must be confirmed for the actual supplied configuration. CO₂ conversion, methane yield, catalyst activation, and other experimental results depend on the catalyst, feed gas composition, reactor conditions, and validated operating procedures. Specifications are subject to final technical confirmation by PENGXIN Machinery.
