Project @ a Glance Contents on the CD Rom
  • A molecular sieve is a material containing tiny pores of a precise and uniform size that is used as an adsorbent for gases and liquids.
  • Molecules small enough to pass through the pores are adsorbed while larger molecules are not. It is different from a common filter in that it operates on a molecular level.
  • For instance, a water molecule may be small enough to pass through while larger molecules are not. Because of this, they often function as a desiccant.
  • They consist of aluminosilicate minerals, clays, porous glasses, microporous charcoals, zeolites, active carbons, or synthetic compounds that have open
    structures through which small molecules, such as nitrogen and water can diffuse.
  • Methods for regeneration of molecular sieves include pressure change, heating and purging with a carrier gas (as when used in ethanol dehydration), or heating under high vacuum.
  • The methodologies used for the preparation of mesoporous zeolite single crystals involve conventional dealumination procedures, such as steaming, acid, and alkaline treatments , or matrixassisted synthesis.
  • Electrostatic deposition process for the fabrication of molecular sieve fibers.
  • Mesoporous molecular sieves such as the all silica DAM-1 and SBA- 15 materials as well as the TiO2 compositions are templated using the micelle forming molecules Vitamin E TPGS and Pluronic.
  • Molecular sieve 4A desiccant will adsorb H2S and CO2, thus reducing corrosion, increasing equipment life and reducing the foul odor associated with H2S in vented gas.
  • Molecular sieves are often utilized in the petroleum industry, especially for the purification of gas streams and in the chemistry laboratory for separating compounds and drying reaction starting materials.
  • Molecular sieves should be used to dry dehydration solvents for electron microscopy.
  • Molecular sieves are used to dehydrate the solvents used in the final stages of dehydration and embedding .
  • Molecular sieve is mainly used to make static dehydration in airtight gas or liquid system, it can remove the moleculars of ethyl alcohol,
    hydrogen sulphide, carbon dioxide, ethylene, acrylica, and also dry the alkane.
  • Molecular sieves are regularly used for the drying and purification of feedstock for refinery applications such as isomerisation, alkylation and reforming, thereby improving operating performance
    and product quality.
  • A disordered mesoporous silica material has been prepared using polymerization of silicate anions surrounding surfactant micelles in the presence of organic salts. The local structure of the material has been investigated using a transmission electron micrograph imaging technique.
  • Molecular sieve zeolites have substantially impacted adsorption and catalytic process technology throughout the chemical process industries; provided timely solutions to energy and environmental problems; and grown to over a hundred million dollar industry worldwide.
  • Fuel cell technology requires fuel clean up as carbon monoxide poisons the electrocatalyst in fuel cell system. Molecular Sieve Silica (MSS) membranes have the physical ability to separate hydrogen from carbon monoxide.
  • Membrane reactor for the water gas shift reaction technology converts carbon monoxide and steam into hydrogen and carbon dioxide.
  • The molecular sieve developed by Massachusetts Institute of Technology engineers reportedly is more precise than conventional methods and has the potential to be much faster.
  • The molecular sieve, which is made using microfabrication technology, is the uniform size of the nanopores through which proteins are separated from biological fluids. Millions of pores can be spread across a microchip the size of a thumbnail.
  • UOP offers the broadest range of molecular sieves and alumina adsorbents in the world with production facilities in the United States, Italy, Japan, and China. UOP is the worldwide leader in the continuing development and manufacture of zeolite and alumina adsorbents and their
    commercial applications.
