Tosoh s Zeolum is a zeolite molecular sieve and is used as an adsorbent in gas product petrochemical refining and other applicationsMolecular sieves are crystalline metal aluminosilicates having a threedimensional interconnecting network of silica and alumina tetrahedra Natural water of hydration is removed from this network by heating to produce uniform cavities which selectively adsorb molecules of a specific size

This sieve like selectivity based on molecular size plus a selectable preference for polar or polorizable molecules gives molecular sieves an extremely high level of adsorption efficiency and permits close tailoring of the adsorbent to the specific useMay 15 32 What is Molecular Sieve Molecular sieves are synthetic zeolite materials engineered with pores of precise and uniform structure and size This allows them to preferentially adsorb gases and liquids based on molecular size and polarity Zeolites are naturally existing highly porous crystalline solids belonging to the class of chemicals known
تفاصيل
Molecular Sieves are synthetic crystalline zeolites in which the atoms are arranged in a definite pattern Internally the structure has many cavities inter connected by smaller pores of a uniform size These pores are only able to accept and pass to the cavities molecules of the same and smaller size hence the name molecular sieveEnriching Lives Everywhere SYLOBEAD Molecular Sieve and Silica Gel Product Portfolio for Drying and Purification in Refining Petrochemical and Natural Gas

Molecular sieves are used as adsorbents and adsorb molecules smaller than their pore size and exclude the larger molecul Different types of molecular sieves are available in the market in various forms such as powder and beads A few examples of various types of molecular sieves are Type 3A Type 4A Type 5A and Type 13XFor molecular sieves with the dehydration function the spent regeneration gas is directly returned to the fuel gas system A typical flow chart of the process is shown in an attachment For molecular sieves that remove mercaptans the spent regeneration gas is treated by the physical absorbent to remove mercaptan and then returned to the fuel gas
