[ 1 ] - تاثیر نانوذرات سیلیکا بر کارایی جداسازی غشای پلیمری آلیاژی ABS/PVAc برای جداسازی هلیم از متان
در دو دهه اخیر بهبود عملکرد غشاهای پلیمری برای جداسازی گازها مورد توجه بسیاری از پژوهشگران قرار گرفته است. یکی از روش های عملی و مهم در این زمینه، افزودن مواد معدنی، مانند نانوذرات سیلیکا، در شبکه پلیمری و ایجاد غشای شبکه آمیخته است. در این پژوهش، نخست اثر افزودن مقادیر مختلف پلی وینیل استات (PVAc) در ترکیب با اکریلونیتریل-بوتادین-استایرن (ABS) برای تشکیل غشای آلیاژی ABS/PVAc به منظور جداسازی گ...
[ 2 ] - Preparation of Poly(ether-6-block amide)/PVC Thin Film Composite Membrane for CO2 Separation: Effect of Top Layer Thickness and Operating Parameters
In this work, novel thin film composite membranes (TFCs) of poly (ether-6-block amide) (Pebax-1657) on a polyvinyl chloride (PVC) ultrafiltration membrane as support were prepared using inclined coating method for CO2 separation. Investigating the effects of top selective layer thickness formed by controlling the coating angle (15-60°) and polymer solution concentration (5-10 wt.%), ...
[ 3 ] - Pebax-Modified Cellulose Acetate Membrane for CO2/N2 Separation
Carbon dioxide (CO2) release from the exhaust gas streams of power plants that burn fossil fuels contributes the most emission of this gas, which includes more than half of the greenhouse effects. Thus, the separation of CO2 from exhaust gases is one of the main environmental concerns. Membrane technology, due to many advantages, has attracted many research attentions among the various gas sepa...
[ 4 ] - Interior Modification of Nano-Porous Fillers to Fabricate High Performance Mixed Matrix Membranes
A new method is developed to enhance the gas separation properties of mixed matrix membranes (MMMs) by interior modification of an inorganic nano-porous particle. Ship-in-a-bottle (SIB), as a novel synthesis strategy, is considered to encapsulate a polyaza macrocyclic Ag-ligand complex into the zeolite Y, which is resulted in a new host-guest nano-composite. It is consequently incorporated into...
[ 5 ] - Gas Permeation Modeling through a Multilayer Hollow Fiber Composite Membrane
In this study, a time-dependent 2D axisymmetric model of a multilayer hollow fiber composite membrane for gas separation is proposed. In spite of the common multilayer membranes, which a dense layer coated on a porous support layer and subjected into the feed stream, here, the porous support is exposed to the feed gas. In this regard, the governing equations of species transport are developed f...
