A new zeolite material designated NU-3 having a molar composition expressed by the formula: 0.5 to 1.5 R2O : Y2O3 : at least 5 XO2 : 0 to 400 H20 wherein R is a monovalent cation or 1 /n of a cation of valency n where n is a whole number of 2 or more, X is silicon and/...
It was found that such zeolites can be obtained using a zeolite synthesis method comprising the preparation of a gel or solution for the ... B Gagea,P Jacobs,J Martens,... - US 被引量: 45发表: 2009年 Synthesis of ITQ-2 zeolite under static conditions and its properties Zeolite ITQ-2...
due to several excellent advantages such as permeability improvement of the selective component, in addition to the enhancement of the thermal stability and the mechanical strength of a polymeric membrane, [17] and its molecular sieving property, thermal resistance and chemical stability [18,19,20]....
PHZ4-x showed both the highest qe and k2, which was consistent with its high uptake amount and rate. The intra-particle diffusion model (detailed in Supporting Information, Equation S(5)) was applied to study the diffusion process. In Fig. 7C, none of the multi-segment lines passed ...
Preparation of high-silica SSZ-13 zeolite membranes High-silica SSZ-13 zeolite membranes were fabricated by using the secondary growth method. Homemade asymmetric porous α-Al2O3 tubes (O.D: 13 mm, I.D: 9 mm, 200 nm average pore size in top layer of outside tube) were used to synthe...
membrane separation, coagulation and filtration, electrochemical processes, and adsorption techniques to purify heavy metals and dyes from wastewater (Iwuozor et al.2021). Among these techniques, the adsorption method is a widely used method in the removal of heavy metals and dyes with its advantag...
Sulfur hexafluoride (SF6) is a greenhouse gas with a global warming potential of 23900 times higher than CO2. It is essential to develop effective methods to separate and recover SF6 from spent gas to prevent its strong release into the atmosphere. Herein high-quality SSZ-13 zeolite membranes ...
In this chapter, we have tried to convey the beauty and diversity of zeolite framework structures, to introduce some of the jargon used to describe them, and to outline some of the techniques used to characterize them. The main feature of a zeolite structure is its framework type, which ...
