Overview
The K-PSA Series Hydrogenation High-Pressure Reactor is a precision-engineered laboratory-scale reaction system designed for catalytic hydrogenation, high-pressure synthesis, and kinetic studies under controlled temperature and pressure conditions. Based on the Couette flow principle and sealed batch reactor architecture, it integrates robust mechanical stirring with precise thermal and pressure regulation—enabling reproducible operation in demanding chemical environments including viscous media, heterogeneous suspensions, magnetic catalysts, and thermally sensitive intermediates. The reactor is widely deployed in academic research labs, pharmaceutical process development, fine chemical synthesis, and materials science applications where strict control over H₂ partial pressure, residence time, and mass transfer efficiency is critical.
Key Features
- Multi-layer forged stainless steel construction (304, 316L, 310S, 904L, Hastelloy, or titanium options available), machined as a single monolithic unit to ensure structural integrity at elevated pressures
- Dual-seal configuration: selectable soft-seal (PTFE/gasket-based) or hard-seal (metal-to-metal) systems compliant with ASME B16.5 Class 600 standards
- Integrated safety architecture: real-time overpressure relief via Hastelloy C-276 rupture disc; overtemperature cutoff with audible/visual alarm; programmable time-out shutdown
- High-torque magnetic coupling drive (up to 20 N·m) powered by a brushless DC motor with SmCo permanent magnets—ensuring silent, maintenance-free operation across 0–1000 rpm with bidirectional rotation control
- Modular heating system: fully enclosed stainless steel heating jacket with embedded rapid-conduction elements; power output adjustable from 0–2500 W
- PID-based dual-loop temperature control (±1 °C accuracy) with optional ramp-hold programming; compatible with K-type thermocouples (316L sheathed, Φ2.0 mm)
- Quick-release clamp design (dual Φ3 mm or Φ6 mm external interface ports) for efficient assembly/disassembly without tools
Sample Compatibility & Compliance
The K-PSA reactor accommodates diverse sample types—including slurries with solid catalysts (e.g., Pd/C, Raney Ni), viscous organometallic solutions, air-sensitive reagents, and multiphase systems requiring gas–liquid–solid mass transfer. Internal linings (optional) include PTFE, quartz, PPL, or steel-clad configurations to resist corrosion from strong acids, halogenated solvents, or hydrogen sulfide. Pressure containment meets ISO 10287:2018 requirements for laboratory pressure vessels; all pressure instrumentation (analog dial or digital display gauges) is calibrated traceable to NIST standards. The system supports GLP-compliant operation when paired with audit-trail-capable controllers (optional upgrade).
Software & Data Management
While the base model operates via front-panel LCD interface with manual setpoint entry, an optional PC-integrated control module enables RS485/USB communication for remote monitoring and data logging. This module records timestamped pressure, temperature, stir speed, and elapsed time at user-defined intervals (1–60 s resolution), exporting CSV files compatible with MATLAB, OriginLab, or LIMS platforms. All logged parameters are stored with metadata (operator ID, batch number, method name) to satisfy FDA 21 CFR Part 11 requirements for electronic records and signatures when validated per GxP protocols.
Applications
- Catalytic hydrogenation of unsaturated organic compounds (alkenes, alkynes, nitroarenes, nitriles) under controlled H₂ partial pressure
- High-pressure hydrothermal synthesis of metal–organic frameworks (MOFs) and nanomaterials
- Hydrodesulfurization (HDS) and hydrodenitrogenation (HDN) screening in fuel chemistry research
- CO₂ hydrogenation to methanol or formic acid using heterogeneous catalysts
- Reaction calorimetry via temperature profiling during exothermic addition steps
- Long-duration stability testing of catalysts under simulated industrial conditions
FAQ
What maximum operating temperature does the K-PSA-100ML support?
Standard configuration supports up to 350 °C; optional high-temp variants (with 310S or Inconel 625 components) extend to 600 °C.
Is the reactor suitable for use with corrosive halogenated solvents?
Yes—when equipped with Hastelloy C-276 wetted parts and PTFE or PPL internal lining.
Can I integrate this reactor into an automated reaction platform?
Yes—via optional analog (4–20 mA) or digital (Modbus RTU) I/O modules for integration with PLC-based process control systems.
Does the system comply with European Pressure Equipment Directive (PED 2014/68/EU)?
The base K-PSA series is CE-marked for non-certified laboratory use; full PED compliance requires third-party Notified Body assessment and vessel-specific documentation.
What is the typical lead time for custom material configurations (e.g., titanium body + sapphire viewport)?
Standard delivery is 4–6 weeks; bespoke engineering (material certification, ASME U-stamp, vacuum bakeout) extends lead time to 10–14 weeks.
