Introduction:
3H-2000PHD high-pressure methane adsorption instrument is a research-grade instrument specially designed for testing the adsorption and desorption of coal and hydrogen storage materials. It can test the total adsorption of gas, hydrogen, etc., and the adsorption constant, especially the desorption rate and other parameters. It is applicable to research institutes and enterprise users of coal bed methane, hydrogen storage material adsorption, and gas outburst research. Technical features:
Test function: Volumetric method high pressure adsorption, desorption isotherm; gas adsorption constant a, b value;
Desorption gas: desorption rate; adsorption time;
Analysis station: 1 analysis station, 2 independent high-temperature vacuum degassing stations, a total of 3 stations;
Test accuracy: Repeatability error is less than ± 2%;
High pressure methane adsorber pressure range: Standard 100bar (optional up to 200bar);
Temperature range: Sample test temperature control from 0 °C to 300 °C; another optional constant temperature water bath, constant temperature oil bath;
High-precision high-pressure adsorption tester temperature control: Instrument internal full gas temperature, constant temperature range of room temperature to 60 °C;
High-pressure methane adsorption instrument test gas: CH4, N2, He, H2, CO2, CO, Ar, Kr, etc.;
Desorption system: The automatic gas desorption system designed for high pressure gas desorption automatically collects the desorption gas in stages. It can realize automatic monitoring and recording of the desorption process and can accurately obtain the initial desorption speed and adsorption time.
Valves: Fully imported 316 stainless steel high pressure pneumatic valve;
Gas system: All stainless steel gas system, all stainless steel pipe, joints, using VCR hard connection, stainless steel sample tube, the system maximum pressure 30MPa;
Dead volume and temperature zone test: Equipped with 99.999% high-purity HE; with HE dead volume test function; with automatic program control HE hot and cold zone temperature zone test function; obtain higher accuracy;
Sample tube: standard 25ml stainless steel sample tube; large sample tube optional;
Pretreatment: 2-way degassing station has independent temperature control and independent timing function, which can support sample degassing at different temperatures and at different times in synchronization with the test; it has "general heating vacuum pumping molecular diffusion mode" and "molecule "Substitution mode" has two optional functions; the molecular displacement mode is more than one times more efficient than the molecular diffusion mode, and can save more than half of the pretreatment time, solving the problem of long sample preparation time in the previous static method.
Anti-pumping: The original hardware anti-pollution device with vortex dust reduction principle, combined with the software anti-pumping program, completely eliminates the ebb boiling phenomenon of volatile samples during high vacuum, thus avoiding the volatiles contaminating the valve piping.
Safety: All pneumatic valves, no solenoid valve, high-performance explosion-proof level;
Equipped with high sensitivity flammable gas detection alarm, the detection limit is better than 3% LEL;
High-pressure methane adsorption instrument Specifications: Size: Thickness 50cm Width 72cm Height 85cm, Net weight: 55Kg, Voltage: AC220v ± 5%, Power is less than 2000 watts
