Overview
The BenchCAT 8000 Octo-Station Integrated Microreactor System is an engineered platform for high-throughput, parallel catalytic reaction evaluation under controlled temperature and pressure conditions. Designed by Altamira Instruments (Pittsburgh, PA, USA) and manufactured under strict quality protocols in Beijing, this system implements fixed-bed microreactor architecture based on precision-machined stainless-steel or Inconel flow reactors, each independently instrumented with mass flow controllers (MFCs), thermocouples, pressure transducers, and back-pressure regulators. The core measurement principle relies on continuous-flow steady-state catalysis, where reactant conversion, selectivity, and deactivation kinetics are quantified via online gas chromatography (GC) or mass spectrometry (MS) interfacing—enabling real-time monitoring of product distribution and catalyst performance across all eight stations simultaneously.
Key Features
- Eight fully independent, identical microreactor stations with individual temperature control (ambient to 600 °C, ±0.5 °C stability), pressure regulation (up to 100 bar), and programmable gas/liquid feed sequencing.
- Modular fluidic architecture supporting gas-phase, liquid-phase, and trickle-bed operation; compatible with syringe pumps, HPLC-grade liquid delivery, and multi-component gas mixing (up to 6 gases per station).
- Integrated safety subsystems including overpressure relief valves, leak detection sensors, automated emergency shutdown (ESD), and redundant pressure/temperature interlocks compliant with ISO 13849-1 Category 3 PLd requirements.
- Front-panel touchscreen interface with embedded controller (Linux-based RTOS) and optional remote access via Ethernet or Wi-Fi for supervised unattended operation up to 72 hours.
- Scalable data acquisition: synchronized logging of >50 process variables per station at 10 Hz sampling rate, stored in timestamped CSV and HDF5 formats with metadata tagging for traceability.
Sample Compatibility & Compliance
The BenchCAT 8000 accommodates catalyst forms including powders, extrudates, pellets, monoliths, and coated foams, with standard reactor cartridges accommodating 0.05–2.0 g catalyst loadings. All wetted parts conform to ASTM A276/A479 stainless steel specifications or equivalent high-temperature alloys. The system meets mechanical design requirements per ASME B31.3 Process Piping Code and electrical safety standards IEC 61000-6-2/6-4. For regulated environments, it supports 21 CFR Part 11-compliant electronic records when paired with validated third-party LIMS or ELN software, including audit trail generation, user role-based access control, and digital signature capability.
Software & Data Management
The system ships with CatalystView™ v4.x — a dedicated Windows-based application enabling method scripting (Python API available), real-time multichannel visualization, automated baseline correction, and kinetic parameter estimation (e.g., TOF, activation energy via Arrhenius analysis). Raw sensor data is exported in vendor-neutral formats (CSV, JSON, HDF5) and integrates natively with MATLAB, Python (Pandas/SciPy), and commercial platforms such as DeltaV DCS and LabArchives ELN. All calibration certificates, firmware logs, and operational history are archived with SHA-256 checksums to ensure ALCOA+ (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) data integrity.
Applications
- High-throughput screening of heterogeneous catalysts for Fischer–Tropsch synthesis, ammonia decomposition, CO₂ hydrogenation, and selective oxidation reactions.
- Accelerated aging and thermal sintering studies under industrially relevant pressure-temperature profiles.
- Reaction mechanism elucidation via isotopic labeling experiments (e.g., D₂, ¹³CO, ¹⁵N₂) with MS-coupled detection.
- Process intensification assessment for microchannel reactor scale-up using dimensionless number correlation (e.g., Reynolds, Damköhler).
- Support for DOE-compliant experimental designs (full factorial, central composite) in catalyst formulation optimization workflows.
FAQ
Can the BenchCAT 8000 operate under corrosive gas environments (e.g., H₂S, Cl₂)?
Yes—optional Hastelloy C-276 reactor liners, ceramic-coated MFCs, and sulfur-resistant pressure sensors are available for extended service life in aggressive chemistries.
Is reactor cartridge replacement tool-free?
All reactor cartridges feature quick-connect Swagelok®-compatible fittings and magnetic alignment guides, enabling sub-2-minute swap without wrenches or recalibration.
Does the system support liquid co-feed with vaporized solvents?
Yes—integrated pre-heated vaporization zones (up to 300 °C) and calibrated liquid injection modules allow precise control of liquid-to-gas molar ratios in multiphase reactions.
What validation documentation is provided?
Each unit ships with Factory Acceptance Test (FAT) report, pressure vessel certification, electrical safety test record, and NIST-traceable calibration certificates for all primary sensors.
Can individual stations run different reaction protocols concurrently?
Yes—each station executes autonomous methods defined in CatalystView™, including staggered ramp rates, distinct gas compositions, and asynchronous sampling triggers.
