z=H d fully automatic
d hydrogen storage material tester introduction
During the process of gas storage and separation of adsorbent materials, it is usually necessary to know the amount of gas adsorption, and the storage and separation links Often carried out under ultra-high pressure conditions. When testing the amount of adsorption, static volumetric equipment must be used to detect how much gas is adsorbed by the adsorbent material as the pressure changes within a fixed volume. Sometimes it is necessary to observe the changes in the amount of gas adsorbed by the adsorption material at different temperatures. This is the role of our high temperature and high pressure adsorption instrument.
After the sample is placed in the sample tube, an inert gas (such as helium) for calibration will first be filled to calibrate the volume occupied by the sample. Then the adsorbate gas will be filled and automatically diffused into the sample tube. As the pressure continues to increase, the amount of gas adsorbed by the sample is constantly changing. When the adsorption is balanced, the software will automatically record the adsorbed amount at this pressure value. This is then automatically repeated until the desired maximum pressure value is reached. We plot the pressure value corresponding to the adsorption amount to obtain the adsorption isotherm
.
For some samples, the adsorption amount at different temperatures is completely different. At this time, we will also test the changes in the amount of gas adsorbed by the sample at different temperatures. For all these complex operations, JinAipu Technology's fully automatic hydrogen storage material tester H
has completely realized automation!
JinAipu Technology is a professional manufacturer of high-temperature and high-pressure adsorption instruments
. Its fully automatic
hydrogen storage material tester
H
currently reaches the highest temperature of
br/>Celsius, the maximum pressure is
Br. Under such high temperature and high pressure conditions, the overall quality requirements for the instrument are very high. The sealing method must be
R sealing technology to ensure no air leakage. To ensure that the test pressure pipeline system connection must be an integral cartridge design and use micro-welding technology, otherwise air leakage will easily occur between components. The pneumatic valve connected to R instead of the solenoid valve must use an original vacuum pump to ensure the high vacuum required for the test. Of course, it must also be a high-quality pressure sensor to monitor the real-time changes in pressure.
High temperature and high pressure adsorption testing
It is very important in the fields of carbon dioxide capture, shale gas storage, hydrogen storage industry, oil exploration and gas separation. In addition, it is crucial to understand the adsorption properties of some adsorption materials such as catalysts, molecular sieves, activated carbon, etc., and research on fuel cells, battery flue gas scrubbers, and hydrocarbons.
