Dual Light Path Photothermal Catalysis System
System Advantages
1.Pressure-reducing system in the system, which can be directly connected with the reaction gas cylinder, the pipeline is equipped with proportional unloading valves, high-precision pressure gauges and pressure sensors, and all temperature control points and pressure monitoring points are equipped with over-temperature and over-pressure alarms for automatic interlocking protection.
2.Feeding system, when passing into different gases, the corresponding gas flow coefficient can be selected or inputted in the flow coefficient table, so as to realise the diversity and accuracy of gas types.
3.Mezzanine temperature-controlled standard gas module, reaction liquid such as toluene, ethanol, etc. in the pressure-resistant tube, pass into the reaction gas or inert gas into the module, bring the effective gas of ppm level into the reactor, control the temperature of the module and then control the concentration of the gas through the water-bath circulating water machine; thus, it can greatly reduce the cost of the experiment and solve the difficult problem that the standard gas is expensive.
4. Constant pressure system, with low pressure and high pressure dual pressure system, according to the experimental pressure to select the corresponding pressure system, to provide stable and accurate, stable experimental environment for the catalyst.
5.The system control all adopts PLC software automation control, real-time monitoring of the reaction process, automated data processing, and provide a full set of experimental programmes. The screen adopts industrial control touch screen PLC, which can be used to change the programme at any time according to the demand. Xinshi Ke shinsco provides gas chromatograph, liquid chromatograph, electrochemical workstation, TPR, TPD, SPV, TPV, Raman and other testing and analysis instruments.
6) The system integrates feeding system, constant pressure system, steady flow system, preheating system, reaction system, product collection system and PLC control system.
