催化剂分析仪 BELCAT II

Unlock state-of-the-art catalyst characterization with the BELCAT II. The performance of solid catalysts is shaped by specific surface properties, with factors like nature and distribution of active sites, acidity, basicity, redox behavior, electronic structure, and surface morphology all playing critical roles in determining catalytic activity, selectivity, and stability. The BELCAT II delivers precise analysis of metal dispersion rates, metal surface areas, and average particle size for supported precious metal catalysts, helping researchers enhance catalyst performance while reducing costs. In addition to providing measurements of specific surface areas (BET) and adsorption kinetics, the BELCAT II determines adsorption capacity through breakthrough curve analyses. These data are essential for the development of innovative adsorbent materials. As a comprehensive catalyst analyzer, it combines all functions in a single device, offering broad applicability and extensive customization to support diverse research and development objectives.

All-In-One, Fully Automatic and Multi-Purpose Analyzer Why BELCAT II

Discover the standout capabilities of the BELCAT II instrument. Below is a list of its key features, designed to provide comprehensive and reliable catalyst analysis while offering flexibility to suit diverse research and development requirements.

Multi-Purpose Gas Dosing Design The integrated multiline gas manifold allows simultaneous connection of up to eight different gases - including two corrosive types - which are internally distributed throughout the system. This smart design supports software-controlled blending, enabling precise generation of customized gas mixtures directly within the unit. These blends can be used during sample pretreatment, analysis, pulse loop operations, and automated calibration. By eliminating the need for premixed gases and minimizing external tubing, the system enhances workflow efficiency, reduces operating costs, and significantly lowers the risk of leakage.

Superior Temperature Control Experience rapid heating and cooling with a compact split furnace designed for high performance. Heating rates reach up to 110 °C/min from 50 to 500 °C, or 80 °C/min from 50 to 1000 °C, with a maximum operating temperature of 1100 °C. Integrated fan-assisted cooling shortens turnaround times, reducing the temperature from 400 to 50 °C in just 30 minutes. This boosts sample throughput and minimizes downtime. For advanced subambient applications, the CATCryo II cryogenic option delivers exceptional cooling down to -120 °C. It sets new standards in thermal management, cooling from 800 to 30 °C in only 10 minutes – unlocking new possibilities in adsorption research, material characterization, and precision-controlled experiments.

Outstanding Safety Measures Features an auto-locking safety-door, overheat protection, automatic shutdown, integrated alarms, and optional gas detection for the highest level of operational safety. The supplied zeolite trap – to remove moisture during TPR experiments – eliminates the need for liquid nitrogen.

Triple Sample Cell Design State-of-the-art design ensures efficient gas preheating and maximizes throughput for demanding workflows. The cylindrical design of the tube enhances ease of handling and increases safety by being tension-free and less prone to breakage.
