 Molecular sieve is a crystalline aluminosilicate,endowed with many features as follows by its uniform pore diameter and extremely large specific surface area:(1)It has selective absorption according to different sizes and shapes of molecules,namely,only molecules smaller than the pore diameter of the molecular sieve can be absorbed.(2)It can selectively absorb molecules with small polarities and unsaturated molecules.The greater the polarity is and the higher the unsaturated degree is,the stronger the selective adsprptive capacity.(3)It has strong water absorbability and the water absorbing capacity is relatively high temperature,relatively large space velocity and relatively low water content.Main products of our company in industrial applications include 3A,4A,5A,10X,13X and copper molecular sieves widely applied in the petroleum industry,the chemical industry,the natural gas industry and the air separation industry etc.and well-expected by users.

Properties and uses of molecular sieve:

Types	Bulk density	Static water absorption	Attrition loss	Applicatiom
3A	0.60-0.70	19-20	0.3-0.6	Used for drying petroleum cracking gas and olenfin
4A	0.60-0.70	20-21	0.3-0.6	Used for drying natural gas and separating allkane
5A	0.60-0.70	20-21	0.3-0.6	Applied in processes including drying and separation of air,dehydration and desulfurization of natural gas,densulfurization of petroleum gas
5A-DW	0.45-0.50	21-22	0.3-0.6	Applied to de-waxing jet fuel and diesel,depressing pour point of jet fuel thereof,and decarbonizing gas and liquid and separating aromatic hydrocarbon
10X	0.55-0.65	23-24	0.3-0.6	Efficient absorbent,used for drying,desulfurizing and decarbonizing gas and liquid and separating aromatic hydrocarbon
13X	0.55-0.65	23-24	0.3-0.5	Drying,desulfurizing and purifying petroleum gas and natural gas
