Dual Light Path Photothermal Catalysis System

Short Description:

TK-DPTC dual optical path photothermal catalysis system is suitable for photothermal co-catalysis, evaluation and screening of photocatalytic catalysts.
It is mainly applied to high-temperature photothermal catalytic reaction, photothermal co-catalysis, which can be specifically used in the fields of synthesis and sintering of semiconductor materials, preparation of catalyst materials, evaluation of activity of catalyst materials, hydrogen production by photolysis of water, oxygen production by photolysis of water, reduction of carbon dioxide, gas-phase photocatalysis, photocatalytic degradation of formaldehyde gas, VOCs, NOx, SOx, nitrogen fixation and so on.

TK-DPTC dual optical path photothermal catalytic system (<5MPa) is a set of fixed-bed photothermal reaction device used to complete the evaluation and screening of catalyst activity, applicable to gas, liquid or gas-liquid feeding at the same time; gas-solid, liquid-solid, gas-liquid-solid reaction, able to achieve automatic control of the temperature, gas-phase flow rate, liquid-phase flow rate, the reaction temperature is able to achieve the programmed temperature rise (linear heating), through the programmed temperature rise settings The heating time and holding time of the experimental temperature can be set through the programmed heating, and the experimental products under different pressures and temperatures can be tested and analysed on-line in stages with the GC and other analytical instruments.

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.
