| Introduction: a kind of alkali aluminosilicate and able to absorb molecules with their critical diameters no more than 10A. Applications: a) Dry gas, purify raw air material: get rid of H2O and CO2. b) Desulfurate liquid hydrocarbon and natural gas: get rid of H2S and thioalcohol. c) Molecules can be adsorbed by molecular sieve 3A, 4A and 5A can be adsorbed by 13X. d) Can adsorb molecular whose diameter is a little less than critical diameter, such as some aromatic hydrocarbon and branched-chain hydrocarbon. Formula: Na2O·Al2O3·2.45SIO2·6.0H2O Specification: Item | unit | target | Shape | | pellet | sphere | Diameter | mm | 1.5-1.7 | 3.0-3.3 | 1.0-1.6 | 3.0-5.0 | Size | % | ≥98 | ≥98 | ≥96 | ≥96 | Bulk density | g/ml | ≥0.54 | ≥0.54 | ≥0.60 | ≥0.60 | Wear ratio | % | ≤0.20 | ≤0.25 | ≤0.20 | ≤0.20 | Crushing strength | N/p | ≥30 | ≥45 | ≥10 | ≥60 | H2O adsorption | % | ≥25 | ≥25 | ≥25 | ≥25 | CO2 capacity | nl/g | ≥14 | ≥14 | ≥14 | ≥14 | Packing water | % | ≤1.5 | ≤1.5 | ≤1.5 | ≤1.5 |
