Abstract Carbon membranes have great potential for highly selective and cost‐efficient gas separation. is chemically stable it relative cheap. The controlled carbonization of a polymer coating on porous ceramic support provides 3D carbon material with molecular sieving permeation performance. the blend gives turbostratic domains randomly stacked together sp 2 hybridized sheets as well 3 amorphous carbon. In evaluation sieve membrane, hydrogen could be separated from propane selectivity 10...
Several astrophysically relevant solid oxides and silicates have extremely small opacities in the visual near-infrared their pure forms. Datasets for imaginary part k of complex indices refraction are hardly available these wavelength ranges. We aimed at determining spinel, rutile, anatase, olivine, especially region. Our measurements were made with impurity-containing, natural, synthetic stardust analogs. Two experimental methods used: preparing sections natural minerals synthesizing melt...
Chabazite (CHA)-type zeolites are promising for the separation of CO2 from larger molecules, such as N2 (relevant to postcombustion carbon capture) and CH4 natural gas/biogas upgrading). In particular, pore size CHA (0.37 × 0.42 nm2) can recognize slight molecular differences between (0.33 nm) (0.364 or (0.38 thus allowing in favor through membranes. Furthermore, siliceous constituents zeolite reduce adsorption capacity toward smaller H2O molecule (0.265 and, thus, permeation rate. This is...
An industrial ceramic nanofiltration membrane (pore size 0.9 nm) was tested in a Canadian oil field for more than 12,500 h to treat wastewater directly from daily operations, without any type of pre-treatment. This contained high content total suspended solids (13 510 mg/kg), and organic carbon (31 134 mg/kg). The unit operated at different transmembrane pressure (TMP) set points (4-16 bar) recovery (40-80%). data show that ion compound rejection depend strongly on combination both TMP...
This study investigates the influence of CHA selective layer's thickness, coated on a mono-channel alumina support using secondary growth method, performance CO2 separation from CH4. The membrane thickness was explored by adjusting concentration and duration seeding process, as well distribution crystal size in suspension. Single gas analysis results revealed that utilizing smaller seeds, with an average crystallite approximately 600 nm, exhibited highest performance. Furthermore, 2.1 μm...
A commercial titania ceramic nanofiltration membrane unit with a permeate flow capacity of 20 m3/h was used to reduce ion concentration, Total Suspended Solids (TSS) and Organic Carbon (TOC) in recycle water from Canadian oil sands mine. This unit, the first its kind, tested for almost two years evaluate performance under actual process conditions. paper focuses on results at 50% stage cut. strong correlation between specific flux rejection found, highest mass rejections observed lowest...
Carbon capture on-board ships represents a powerful technological measure in order for the shipping industry to meet very stringent GHG emission reduction requirements. Operation within ship environment introduces number of constraints associated mainly with space, energy supply, and safety which have be addressed using compact yet efficient solutions. To this end, solvent-based membrane CO2 offers several advantages has necessary maturity installation. Solvent choice remains critical issue...
This work aims to investigate and develop a concept for CO2 separation based on PDMS/SSZ–13 (high-Si CHA) composite membranes. Firstly, an Al2O3 support was coated with SSZ-13 zeolite layer, then increase the performance of membrane, Polydimethylsiloxane layer effectively deposited homogeneously cover cracks defects layer. The results single gas permeation measurements displayed notable in ideal CO2/CH4 selectivity up 428 at lowest PDMS concentration 0.5 vol%. Moreover, coating time 10 min...
Small-pore zeolites, such as CHA (0.38 nm), have pores that are comparable to the size of CH4 but larger than CO2. As a result combination diffusion and adsorption, these membranes projected strong CO2/CH4 selectivity CO2 permeance. During this work, SSZ-13 were synthesized, evaluated, characterized by X-ray Diffraction, Field-Emission Scanning Electron Microscopy, Energy-Dispersive Spectroscopy, Fourier Transform Infrared Solid-State Nuclear Magnetic Resonance, Thermogravimetric Analysis....
