Test Precision:Repeated error is less than ±2%.

Analytical stationOne sample analytical station, two independent high temperature pre-treatment stations. 

Pressure scope:From highly vacuum to maximum 200bar. 

Pressure precision :Imported high precision pressure sensor, with precision of up to 0.01% FS and long-term utilization stabilization of 0.025%FS.

Temperature scope:0℃ to 400℃

Test gas:CH4, N2, H2, CO2, CO, Ar, Kr and so on; 

Control system:The valves adopted are highly safe and high-pressure resistant fully-imported 316 stainless steel high pressure pneumatic valve, which can realize automatic switch on and off within the pressure range of 200Bar; there is no gas leakage in them and they have a service life of more than 0.5 billion times. 

Pre-treatment :it is equipped with “common heating vacuumizing molecular dispersal pattern” and “molecular substitution mode” two optional functions. 

Desorption system:It is equipped with common-pressure automatic desorption system, which can measure the gas desorption volume and desorption velocity in the test coal samples. All the desorbed gases will be 100% collected.

The maximum collection volume for initial 3 to 10seconds free gas will be no less than 18.5L with precision of 0.006L;

The maximum collection volume of desorbed gases in middle period will be no less than 7L with precision of 0.002L;

The maximum collection volume of desorbed gases in last period will be no less than 2.7L with precision of 0.001L;

 


Technical Features and Advantages 

Safety Method 

High safety, it will adopt full pneumatic valve, without solenoid valve, high performance anti-explosion level; interior and exterior of the instruments are equipped with 2 high sensitivity inflammable gas detecting alarms, the detection limitation is higher than 3%LEL.

Pollution prevention 

Beishide originally developed non-obstructive-type environmental control system with principle of vortex dust falling, combining with the flying-prevention procedure; it can eliminate any elutriation and boiling henomenon of samples that are volatile in highly vacuum conditions, so as to avoid polluting the valve pipelines that cause the decrease of systematic tightness.

Air Bath 

The entire interior of the instrument is keeping constant temperature, sample cell, branch, valves and gas sources are all under the same air bath environment, which can avoid troubles in using water bath; it can eliminate the errors caused for sample cell, branch and valves are in different environments for the sake of water batch. 

Air bath temperature: ambient temperature ~60;

Notes: other test temperature shall take advantage of water bath or heating furnace.      

Precautions 

Analytical bit is equipped with protection door, which can put the risks of damage to the laboratory operators resulting from high temperature into an end; more importantly, it can eliminate the influence of ambient air flow changes to the test efficiently, so as to improve the test precision and stability significantly. 

 

Applied Fields 

1. High temperature and high pressure gas adsorption research, supercritical gas properties study, micro pore material adsorption research, hydrogen storage materials property research, coalbed methane research and oil exploration and so on;

2. Its typical applications include catalyst, molecular sieve, activated carbon, carbon nano tube and all kinds of hydrogen storage materials. 

3. Understanding the adsorption properties of materials is essential to the research and development of fuel cell, cell flue gas scrubbing tower and hydrocarbon.
