Activated carbon, molecular sieve, MOF and other adsorbents have significant selective adsorption performance with specific gases, which can be used in air separation, natural gas refining, organic gas vapor retrieving, air and flue gas purification, etc fields.
Fixed-bed reactor is used as multi-component selective adsorption separation reactor, which is widely applied in gas separation, high-purity gas generation, industrial catalysis, exhaust gas treatment, etc flied. The physics adsorption at the fixed-bed is that adsorbent selectively adsorb multi-component absorptive gas, which realizes its application in the industry.
For example, the CO₂ elimination from CH₄ gas, purification of benzene series etc hydrocarbons, multi-component pollutants (VOCs, SO₂ and NH₃, etc) elimination in the air, flue gas purification research, etc. Physics adsorption has high efficiency, low consumption and can be applied with low concentration background, meanwhile do not generate second pollution, which provides the wide application prospects and research value. The breakthrough curve analysis method is the typical method in this flied due to it is close to practical application condition, the adsorbent dosage, adsorption capacity, adsorption rate, selective adsorption effect, purification effect, activation conditions, filter cartridge life span and etc information can be obtained through the curve analysis method.

There is some adsorbent with a certain heightput in the breakthrough volume , meanwhile the adsorbent is fixed in the volume. The mixed gases are put to flow in with carrier gas from inlet, and adsorbed by adsorbent then flow out from outlet. Analyze the gas concentration changes over the time at the outlet, can breakthrough curve be obtained, and the breakthrough time, the preferential adsorption amount and etc., of multi-component gases in mixture exclude carrier gas can be obtained.
