Frequently Asked Questions

What is the difference between 3A, 4A, 5A, and 13X molecular sieves?

The numbers refer to the pore size in angstroms. 3A (3Å) adsorbs water only. 4A (4Å) adsorbs water, ammonia, and CO₂. 5A (5Å) adsorbs normal paraffins and desulfurizes. 13X (10Å) has the largest pores and removes water, CO₂, and larger molecules.

Can molecular sieves be regenerated?

Yes, most molecular sieves can be regenerated by heating to 250–350°C under vacuum or purge gas. This drives off adsorbed moisture and restores adsorption capacity.

What packaging options are available?

We offer 25kg bags, 140kg drums, and bulk packaging. Custom packaging is available upon request.

Do you provide technical support?

Yes, our technical team provides application guidance, selection support, and troubleshooting assistance.
