The addition of polyphenylene sulfide (PPs) to polysulfone (PSf) membranes has been found significantly enhance the separation performance CO 2 /CH 4 and H gases through polar acid-based interactions.
A micro-mesoporous structure of ZTC was synthesized <italic>via</italic> an impregnation method, and the assisted in a faster CO<sub>2</sub> adsorption–desorption equilibrium.
Hydrogen (H2) has become one of the promising alternative clean energy resources. Membrane technology is a potential method for hydrogen separation or production. This study aims to develop new carbon membrane Moreover, permeation behavior H2, CO2, and CH4 through hollow fiber composite derived from P84 co-polyimide with incorporation zeolite (ZCC) was also examined. ZCC synthesized via impregnation sucrose into zeolite-Y pores, followed by carbonization at 800 °C. Thus, this filler high...
Recently, natural gas (mostly methane) is frequently used as fuel, while hydrogen a promising renewable energy source. However, each produced contains impurity gases. As result, membrane separation required. The mixed matrix (MMM) membrane. huge surface area and well-defined pore structure of zeolite templated carbon (ZTC)-based MMM allow for effective separation. the interfacial vacuum in difficult to avoid, contributing poor performance. This research tries improve performance by altering...
Several factors, including the accessibility of energy sources, influence movement human activities in this era. However, humans still rely on fossil sources. For example, petroleum is non-renewable and can pollute environment. As a result, researchers have recently been competing to produce various forms using renewable Ocean current one Indonesia's greatest potentials hydrokinetic turbine device that harness it. Due its ability run low-speed currents, vertical-type Savonius has developed...
This research introduces zeolite carbon composite (ZCC) as a new filler on polymeric membranes based the BTDA-TDI/MDI (P84) co-polyimide for air separation process. The performance was further improved by polydimethylsiloxane (PDMS) coating to cover up surface defect. incorporation of 1 wt% ZCC into P84 matrix enhanced O2 permeability from 7.12 18.90 Barrer (2.65 times) and O2/N2 selectivity 4.11 4.92 (19.71% improvement). PDMS membrane 60%. results showed that onto able increase overall performance.
The demand for efficient and sustainable gas separation technologies is ever-increasing in various industries, including petrochemicals, natural processing, carbon capture. Polymer-based membranes offer a promising solution due to their potential high selectivity energy efficiency. However, achieving optimal performance often requires overcoming the limitations of individual polymers through modifications such as polymer blending. In this study, PSf/P84 blended with low P84 content were...
The zeolite-templated carbon (ZTC) with a unique structure was utilized as new porous filler for preparing mixed matrix membrane (MMM). zeolite-Y used template synthesized via hydrothermal method. ZTC prepared by impregnation of sucrose into the pore zeolite-Y, followed carbonization and removal. obtained characterized X-ray diffraction (XRD), scanning electron microscopy (SEM) N2 isotherm analysis. Results showed that amorphous possess specific surface area 1254 m2/g 0.95 cm3/g total...
The hydrogen adsorption, kinetic and thermodynamic of adsorption onto the zeolite templated carbon (ZTC) were examined at temperature range 30-50 °C ambient pressure. ZTC was prepared from zeolite-Y template sucrose precursor by impregnation method showed its specific surface area 932 m2/g as well 0.97 cm3/g for total pore volume. Analysis physical chemical characteristics materials performed using XRD, SEM, TEM N2 isotherm. results indicated that has some ordered network structure also...
This study aims to enhance the H2/N2 separation performance of polysulfone (PSF) hollow fiber membranes by annealing. X-ray diffraction, SEM, and FESEM were utilized evaluate morphological structural changes in denser annealed PSF membranes. AFM topography images used investigate form roughness Before testing membrane permeation, it was at 120, 150, 190 °C optimize gas performance. Compare all annealing temperatures (120, °C), 150 had greatest selectivity (16.18), but its unsatisfactory...
