Product Details
Overview
The Micromeritics penetration curve analyzer is a flexible gas delivery and management system that can accurately characterize adsorbent performance under process related conditions. It uses a flow-through system to accurately measure the adsorption data of gas/vapor mixtures, and the results are reliable.
This device is safe to operate and highly optimized, suitable for collecting transient and equilibrium adsorption data of multi-component systems. The penetration curve analyzer can be configured with up to six high-precision mass flow controllers and high-performance mixing valves, bringing flexibility to experimental design. The gas delivery design ensures precise control of composition and flow rate while reducing dead volume.
High quality stainless steel columns can be filled with 0.05 to 2.5 grams of adsorbent. Using a high-precision and high-strength resistance heating furnace, the sample can be automatically activated at temperatures up to 1050 ° C.
By using a servo positioning control valve, the working pressure can be controlled between atmospheric pressure and 30 bar. This constant temperature environmental chamber can implement unified temperature control for the entire system at a temperature of 200 ° C, ensuring that the system has no cold spots. The safety door lock system of the penetration curve analyzer ensures the personal safety of the operator throughout the entire analysis process.
The penetration curve analyzer can be equipped with a steam generator to conduct experimental research using important detection molecules such as water. The penetration curve analyzer can be easily connected to Fourier transform infrared spectroscopy and mass spectrometry systems sold in the market for gas identification and quantitative analysis.

Penetration adsorption dynamic analysis
Penetration curve analysis is an important technical method for determining the adsorption capacity of adsorbents under flow conditions. Compared with static adsorption measurement, dynamic penetration adsorption has multiple advantages.
- Easily collect multi-component adsorption data
- Determination of adsorbate selectivity
- Repeated process conditions
When conducting penetration curve analysis, sample preparation is a key step in the analysis process, which can avoid pressure drop and mass transfer limitations.
- When the gap between particles is too small to accommodate the gas flow rate, a pressure drop will occur.
- When the pore size of the material approximates the kinetic diameter of the adsorbate, mass transfer restriction occurs.
Therefore, appropriate particle size control is the key to obtaining experimental results.
Check the penetration curve
-
adsorption
The adsorbent will be adsorbed by the adsorbed gas, so no gas was detected at the outlet of the penetrating column
-
penetrate
Adsorbed gas was detected at the exit of the penetrating column. At this point, the adsorbent will continue to adsorb gas, but it is no longer able to adsorb all the gas that enters the penetrating column
-
saturation
The adsorbent has reached saturation and can no longer adsorb the adsorbate gas, allowing it to freely pass through the penetrating column
Carbon dioxide adsorption
Single component carbon dioxide permeation adsorption experiments were conducted on 13X and 5A zeolites, as well as metal organic frameworks MIL-53 (Al) and Fe BTC.
All materials were analyzed at 30 ℃, and an equimolar mixture of 10 sccm nitrogen and 10 sccm carbon dioxide was continuously introduced during the testing process. In addition, a helium gas flow of 1 sccm was mixed into the intake flow to serve as a tracer gas and help determine the start time of the penetration test.
The penetration curves of the four materials have been normalized by mass and plotted in the coordinate graph below. CO2The total adsorption capacity follows the following trend: 5A molecular sieve>13X zeolite>Fe BTC>MIL-53 (Al).
The table below shows the total amount of adsorption, measured in mmol/g
| material | The adsorption capacity of materials for carbon dioxide |
|---|---|
| 13X zeolite | 2.94 |
| 5A molecular sieve | 3.52 |
| MIL-53 (AI) | 1.23 |
| FE-BTC | 2.30 |
Application scenarios
-
- Natural gas separation
-
Natural gas is a mixture of hydrocarbons and other gases that must be purified before being used in industrial applications, household heating, and food production.
- Direct Air Capture (DAC)
-
The implementation of DAC is difficult due to the low concentration of carbon dioxide in the air and the presence of other impurities (including moisture). Captured CO2It can be stored underground, sold, or converted into high value-added chemicals to offset carbon emissions.
- CO2adsorption
-
Power plants, chemical plants, and refineries are important sources of concentrated carbon dioxide emissions, and their emission concentrations are usually much higher than those in direct air capture (DAC) scenarios, so different process conditions are often required.
- Olefin/paraffin separation operation
-
It is the core part of the petrochemical industry, used for the production of polymers such as polyethylene and polypropylene. These separation processes require a significant amount of energy and will increase CO emissions2Emissions.
- Toxic gas adsorption
-
Porous solid materials have been used in the production of personal protective equipment. In addition, they can also be used to capture toxic gases such as sulfur dioxide, hydrogen sulfide, and nitrogen dioxide in natural gas or other processing materials. Currently, this application is still under development.
- Water adsorption
-
Atmospheric water collection technology can capture moisture from the air, which is of great significance for many areas where clean freshwater supply is limited due to dry climate or increasing agricultural irrigation water use.
- zeolite
-
The pressure swing adsorption (PSA) technology using zeolite molecular sieves such as 5A, 13X, or LiX can selectively adsorb nitrogen gas, which can be used for air separation and oxygen production, and has been commercially applied.
- Silicon particles
-
Amine functionalized silicon particles are an efficient and highly selective adsorbent, and direct air capture (DAC) technology can use this material to directly capture CO2.
- Porous membrane/integral adsorbent material
-
Porous membranes and zeolite or metal organic framework (MOF) materials coated with integral adsorption materials can significantly enhance the separation process
- activated carbon
-
The volatile organic compounds (VOCs) in the automotive fuel system are captured using activated carbon cans, which can reduce VOC emissions.
- Porous aluminum
-
Alumina loaded ionic liquids are highly efficient adsorbents with the potential to separate CO from natural gas2.
