Synthesis of nano-porous molecular sieve from some natural materials
Zeolites due to their structures can be used as molecular sieves for purification of materials and solutions. Zeolites with PHI and SOD structure are so common and applicable for this purpose. Hydroxy sodalite and phillipsite are the more abundant members of zeolites which display good selectivity for very small molecules and some ions such as Sr, Pb, Zn, Cu and Rb. There is not any pure natura...

متن کاملMolecular Sieve Silica Membranes For H2/CO Separation
Membranes have been used for gas separation for quite some time but have seen major growth during the 90’s [1]. For many industrial applications involving gas streams, it is important that membranes resist high temperatures and corrosive environments. As in Table 1, organic membranes are not heat resistant at high temperatures while zeolite membranes have pore sizes too large to separate gases ...

متن کاملSynthesis and Characterization of a Novel Multifunctional Carbon Molecular Sieve
Carbon molecular sieves were prepared from petroleum coke by chemical activation. The effects of activation temperature, holding time, preliminary treatments and activated agent ratio on surface area, pore structure of the carbon molecular sieves produced in our lab were investigated. The specific surface area and average pore size of the carbon are obviously increased with increasing use of ac...
