Nitrogen Adsorption on Molecular Sieve Zeolites: An Experimental and Modeling Study
Separation of nitrogen from a gaseous mixture is required for many industrial processes. In this study, the adsorption of nitrogen on zeolite 4A was investigated in terms of different adsorption isotherm models and kinetics. An increase in the initial pressure from 1 to 9 bar increases the amount of adsorbed nitrogen from 6.730 to 376.030 mg/(g adsorbent). The amount of adsorbed nitrogen increa...
متن کاملSynthesis 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 کاملPhoto-oxidative enhancement of polymeric molecular sieve membranes.
High-performance membranes are attractive for molecular-level separations in industrial-scale chemical, energy and environmental processes. The next-generation membranes for these processes are based on molecular sieving materials to simultaneously achieve high throughput and selectivity. Membranes made from polymeric molecular sieves such as polymers of intrinsic microporosity (pore size<2 nm)...
متن کاملRecent Advances on Carbon Molecular Sieve Membranes (CMSMs) and Reactors
Carbon molecular sieve membranes (CMSMs) are an important alternative for gas separation because of their ease of manufacture, high selectivity due to molecular sieve separation, and high permeance. The integration of separation by membranes and reaction in only one unit lead to a high degree of process integration/intensification, with associated benefits of increased energy, production effici...
