Upscaling polyPOSS-imide membranes for high temperature H2 upgrading
نویسندگان
چکیده
In the present work, potential of polyPOSS-imide membranes designed for purification H2 from a coke gas (utilized in steelmaking industry) is investigated. Aiming at upscaling membrane fabrication, tubular single-channel and multi-channel were prepared, using polyhedral oligomeric silsesquioxane (POSS) nanostructures 6FDA as reactive precursors. The separation performance has been investigated by means single quaternary (H2, CH4, CO2, N2) mixtures, latter used to simulate conditions expected module inlet process upgrading oven gas. Preliminary results obtained on showed that fabricated can achieve high permeance (>2000 GPU), displaying also suitable selectivity towards N2 CH4. these upscaled samples meets those previously disc-shaped lab-scale membranes. These revealed promising via interfacial polymerization ceramic porous supports upgrading.

Effect of Dehydration Temperature on the H2 Separation Potential of Hydroxy Sodalite Zeolite Membranes
The main goal of this work was to synthesize and evaluate the effect of dehydration temperature on the potential application of hydroxy sodalite zeolite membrane. Hydroxy sodalite zeolite membranes were synthesized via direct hydrothermal method onto a tubular alumina support without seeding in a hot air oven. The synthesized membranes were characterized by X-ray diffraction (XRD) and scanning ...

Hybrid organic/inorganic hyper-cross-linked membranes based on imides covalently bonded with polyhedral oligomeric silsesquioxanes (POSS) have recently been developed for gas-separation applications under high pressure and/or temperature conditions. Their molecular sieving capabilities have been shown to depend on the nature of the organic dianhydride precursor. In the present work, realistic m...

Polybenzimidazole (PBI)-based high-temperature proton exchange membranes (PEMs) offer many advantages that aid in a simplified fuel cell system design. Such benefits include high resistance to fuel impurities (most notably carbon monoxide), fast electrode kinetics, and simplified water and thermal management due to operational temperatures above 120 ◦C.[1] As a result of its intrinsic physicoch...
متن کاملInitiation in H2/o2: Rate Constants for H2 O2 → H Ho2 at High Temperature
The reaction between H2 and O2 has been studied in a reflected shock tube apparatus between temperatures of 1662–2097 K and pressures of 400–570 torr with Kr as the diluent gas. O atom atomic resonance absorption spectrometry (ARAS) was used to observe absolute [O]t under conditions of low [H2]0 so that most secondary reactions were negligible. Hence, the observed [O]t was the direct result of ...
