The potential of advanced polymer or hybrid polymer membranes to reduce CO2 emissions in steel production was evaluated. For this, a conceptual process design and assessment was performed for a process that is a combination of carbon recycling and electrification of the steel making process. The results indicate a CO2 avoidance of 9%. CO2 emissions...

In the present work, the high-temperature and long-term hydrothermal stability of novel polyPOSS-imide membranes for high-temperature hydrogen separation is investigated. The polyPOSS-imide membranes are found to exhibit an appropriate stability up to 300 °C. Above this temperature the membrane selectivity rapidly decreases, which is seemingly rela...
Article
A 0.9 µm PdCu (69 wt% Pd) membrane prepared by an electroless plating method on a ceramic tubular support was tested in hydrogen sulfide containing streams. H2S/H2 mixtures with 40 and 100 ppmv of H2S were tested in order to observe the reversibility of sulfur addition. The membrane permselectivity operating in H2S/complex mixtures with around 32 p...
Article
Pre-combustion capture of carbon dioxide requires the industrial separation of carbon dioxide from hydrogen-rich streams. The present study analyses the thermodynamic efficiency penalty of this separation step and the achievable carbon capture ratio, with particular focus on high-temperature separation technologies: sorption-enhanced water–gas shif...

Palladium membranes are being developed for the separation of hydrogen from syngas in industrial applications. However, syngas constituents carbon monoxide, carbon dioxide, and steam are known to adsorb at the membrane surface and inhibit the permeation of hydrogen. The current study combines an experimental study and modelling approach in order to...

Precombustion CO2 capture can be feasible with mature palladium-based membranes in modules. Before moving on to demonstration, benchmarking of membranes is a crucial step in their introduction. The strategy presented here, consisting of matching results from experiments and model development, will be a valuable tool in benchmarking membrane perform...
Article
PdCu membranes prepared by sequential electroless plating were integrated into a hydrogen production and purification process. Hydrogen was produced from methane through catalytic partial oxidation and wet catalytic partial oxidation with Ni-based catalysts. Membrane permeance was measured with thermal cycles in an inert and hydrogen atmosphere at...
Article
In this study, a bench-scale Pd membrane reactor was used to carry out the methane steam reforming reaction under realistic operating conditions: 580 °C, 28 bar(a) and GHSV values up to 950 h−1. The continuous withdrawal of the H2 product resulted in a maximum CH4 conversion of 98% and a H2 production rate of 0.13 N m3 h−1. A continuous methane con...
Article
A PdCu membrane was characterised and then tested in complex hydrogen containing streams from methane oxidation and reforming processes. The hydrogen permeance and stability of the PdCu membrane, prepared by electroless plating, was analysed in pure hydrogen and by thermal cycling in inert and hydrogen atmospheres. This membrane was then placed in...
Article
The effect of H2S addition to a hydrogen production followed by hydrogen purification system was studied. NiMgO catalyst was employed in the catalytic reactor for hydrogen production from methane via catalytic partial oxidation (CPO) and wet-catalytic partial oxidation processes (wet-CPO). A PdCu membrane was located in a membrane module to purify...

PdCu membranes were prepared by the electroless plating of Pd membranes prepared on ceramic tubular supports. Different PdCu membranes were prepared with Pd content between 45 and 77 wt% and a total metal layer between 0.5 and 1.9 μm thickness. The alloying step was performed in two ways to compare and establish the required alloying time for obtai...

Article
Hydrogen membrane reactors have been identified as a promising option for hydrogen production for power generation from natural gas with pre-combustion decarbonisation. While Pd or Pd-alloy membranes already provide good hydrogen permeances the most suitable catalyst design for steam reforming in membrane reactors (SRMR) is yet to be identified. Th...

A major drawback of polymeric membranes for pervaporation is their limited solvent and temperature stability. This means that for several potential applications the membrane lifetime in combination with a relatively low performance is the limiting factor for introducing them into the market. More stable membranes are therefore needed. ECN has devel...
