Zeolites for Molecular Sieves | https://www.tosoh.com

Zeolite Molecular Sieves: Chemical Formula / Diagram: MeO•Al 2 O 3 •mSiO 2 •nH 2 O (Me: Metal Ion) Product Overview: Zeolum is a synthetic zeolite possessing strong selective adsorption properties. Zeolum is suitable for drying, purifying and separating a wider variety of feeds than any other adsorbent. Applications: Gas Production:

CRUDE SAND

Wash down the sides of the flask and then add a 2.5 percent potassium permanganate solution until a distinct pink or brownish color appears (see Note 5). While hot, add a stannous chloride solution drop by drop until the color of the ferric iron is discharged; then add just one more drop (see Note 6).

Propylene/propane separation by vacuum swing adsorption

Apr 16, 2004 · A vacuum swing adsorption process using 13X zeolite pellets with five steps was designed to split an equimolar mixture of propylene/propane: pressurization with feed; high‐pressure feed; high‐pressure purge with product; cocurrent blowdown; and counter‐current vacuum blowdown, where the enriched propylene product is withdrawn.

3A, 4A, 5A, 13X… What’s the Difference? – Hengye

Type A All molecular sieves are composed of sodium and aluminosilicate, which are grown to form a three-dimensional crystal structure. It’s this crystalline structure that allows molecular sieve to adsorb some molecules while rejecting other molecules that are too large to fit inside the crystal. When A-Type crystals are grown, they initially are all Type 4A, meaning the pore openings are ...

Moleclar sieve 5A – GAHARCERAM

Molecular sieves are crystalline metal aluminosilicates having a three-dimensional interconnecting network of silica and alumina tetrahedra with uniform pore size. These pores have diameters about 3-10 angstrom, thus larger molecules exclude while smaller molecules (such as water) can be adsorbed easily. According to this property, molecular sieve technology is generally
