Introduction: VDSORB-90HP is a multi-function temperature-programmable chemical adsorption instrument capable of realizing experiments such as HPTPD\HPTPR\HPTPO. Combining with the functions of custom experimental procedures, it can realize various types of high pressure and atmospheric pressure catalytic characterization experiments such as high pressure hydrogenation, oxidation, Reduction, catalytic cracking, exhaust gas denitrification, etc. Features: 1. Using self-developed SPID (SMART-PID) temperature control technology, taking into account the smoothness of the warming curve of the low temperature section and the high temperature section, the most likely to avoid the abnormal peak due to the fluctuation of the heating curve; 2. Adopt imported high-precision high-precision mass flow controller to achieve accurate flow control and fast response time; 3. The thermal conductivity detector (TCD) has high sensitivity and adopts imported high-impedance helium tungsten wire. The temperature fluctuation range of the detector is less than 0.05°C, which greatly improves the detection sensitivity and has strong anti-interference ability. 4. The gas path is optimized, the dead volume of the system is very small, improving the reproducibility and sensitivity of the experiment; 5. Built-in thermostat box, to ensure that there is no cold spot in the air path, including joints, valves, etc.; 6. Built-in automatic high-pressure switching valve, to achieve full automation of the experimental process; 7. The use of automatic lift reactor, to achieve full automation of the experimental process. Combines strong cooling system to achieve efficient and rapid cooling; 8. Gas on-line gas mixing can be achieved to complete various types of catalytic characterization experiments; 9. Equipped with a variety of cold traps, filters, buffer rings, flexible use according to specific experiments; 10. The instrument uses aluminum alloy module as a whole Technical Parameters: Reproducibility: <2% Catalyst loading: 5 to 200 mg Reaction pressure: 0.1～10MPa Gas flow range: 0 ~ 100sccm (expandable) Gas flow accuracy: <0.5% F.S. Reactor temperature: RT ~ 1100 °C (reaction pressure: <3MPa) RT～800°C(reaction pressure:<10MPa) Reactor temperature control accuracy: <0.1°C Furnace heating rate: 0~50°C/min Furnace heating curve smoothness: <0.5% Detector baseline noise: <30μA Detector baseline drift: <50μA/30min Detector temperature range: RT～250°C Detector temperature control accuracy: <0.05°C Incubator temperature range: RT～250°C Incubator temperature control accuracy: <1°C Steam generator temperature range: RT ~ 250 °C Steam generator temperature control accuracy: <1°C Cold trap temperature range: -196°C～RT
