• Molecular Sieve

3A Molecular Sieve

3A molecular sieve has an effective pore size close to 3Å and is mainly used for water adsorption, not adsorbing molecules larger than 3Å in diameter. Through pore shaping and structural optimization according to industrial application requirements, our produced molecular sieves possess high selectivity, faster adsorption rate, more regeneration cycles, higher crush strength, and resistance to contamination. This improves the utilization efficiency and extends the lifespan of molecular sieves. They are the preferred desiccant for gas and liquid-phase deep drying, refining, and pre-purification in the petroleum and chemical industries.

4A Molecular Sieve

4A molecular sieve has a pore size of 4Å and selectively adsorbs water, methanol, ethanol, small amounts of hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, and propylene. It does not adsorb molecules with a diameter larger than 4Å (including propane). It exhibits higher selectivity for water adsorption than any other molecules and is one of the most widely used molecular sieve types in industrial applications.

13X Molecular Sieve

13X molecular sieve has a pore size of 10Å and selectively adsorbs molecules smaller than 10Å. It is used for deep drying of general gases and for removing H2O and CO2 in air separation units. It can adsorb the same molecules as 3A, 4A, and 5A molecular sieves, and it can also adsorb larger molecules with a critical diameter (such as aromatic and straight-chain hydrocarbons).

Activated Alumina

Spherical activated alumina is a white, porous granular adsorbent. It has a fine and uniform microstructure, smooth surface, high mechanical strength, strong moisture absorption, and does not swell or crack after absorbing water, while remaining non-toxic, odorless, and insoluble in water and ethanol. Activated alumina is an efficient desiccant for deep drying of trace amounts of water and is particularly suitable for non-thermal regeneration systems.

Spherical particles: 3-5mm

It is commonly used in adsorption dryers, air treatment for instrument air drying, and can also serve as a carrier for certain catalysts. For example, when impregnated with substances like potassium permanganate, it can absorb organic acid ions, formaldehyde, sulfides, and become an important means of environmental waste gas treatment.

Carbon Molecular Sieve

Carbon molecular sieve is an excellent non-polar carbon material. It mainly consists of elemental carbon and appears as a black cylindrical solid. It contains a large number of micropores with diameters ranging from 0.28 to 0.36nm, as well as a small amount of macropores and mesopores. The micropores contribute to over 90% of the total pore surface area of the carbon molecular sieve, and the specific surface area of the micropores generally exceeds 1000m2/g. The ability of carbon molecular sieve (CMS) to separate air depends on the different diffusion rates of oxygen and nitrogen in the micropores of the carbon molecular sieve. Due to the difference in kinetic diameter of gas molecules, the components of gas mixtures can be effectively separated.

The commonly used carbon molecular sieve should have an internal micropore distribution within the range of 0.28-0.36nm. Within this micropore size range, oxygen (with a kinetic diameter of 0.346nm) can quickly diffuse through the micropore opening into the pore, while nitrogen (with a kinetic diameter of 0.364nm) has more difficulty passing through the micropore opening, achieving the separation of oxygen and nitrogen. Carbon dioxide (with a kinetic diameter of 0.33nm) can also rapidly diffuse into the pore through the micropore opening and is a relatively strongly adsorbed gas.

It is typically in a cylindrical shape.

When packed in a PSA (Pressure Swing Adsorption) nitrogen generator, it can produce high-purity nitrogen gas with concentrations exceeding 99%.
