Hydrotalcite-based materials have been identified as suitable materials for high temperature (400 8C) adsorption of CO2. In pre-combustion decarbonisation processes for natural gas based power cycles, it should be possible to use this material to improve conversions in the water-gas shift (WGS) and steam-reforming (SMR) reaction. The efficiencies for electricity production from natural gas have been calculated for some different system configurations, in which hydrotalcite-based material could be used. The calculated efficiency penalties ranged from 5.5 to 8.6 percentage points. The assumptions made in the system study have been tested on the laboratory scale. Hydrotalcite-based materials are found to be an excellent choice for use in the sorption-enhanced WGS reactor. The requirements for very low residual concentrations of CO2 at 400 8C and large amounts of catalyst in the sorptionenhanced SMR reactor make its application less likely. Suggestions are made to how the SESMR could be improved.

Publisher Summary This chapter provides an overview of the current status of the membrane development as a part of the R&D trajectory of hydrogen membrane reactors at Energy research Centre of the Netherlands (ECN). It focuses on the development of advanced technologies for power generation with carbon dioxide (CO2) capture. Membrane development at ECN focuses on the development of thinner and cheaper metallic membranes with higher permeation rates. Dense Pd/Ag membranes consist of a very thin layer of alloy supported by a porous inorganic substrate. The Pd/Ag membranes are made by electroless plating. Pure (gas-tight) palladium layers can also be prepared, varying in thickness between 0.5–4 microns. Silver is deposited on top of the thin pure Pd-membrane and sintered to obtain the required alloy composition. By optimizing the electroless plating technique, it is possible to manufacture membrane layers with a thickness of 3–5 microns on ceramic supports. The dense membranes show high hydrogen fluxes of up to 105 m3/m2hbar0.5 at 400°C. At low feed pressures, no nitrogen flux is detected and if the detection limit of the equipment is taken as the measured nitrogen flux, then the permselectivity is >1000.

Publisher Summary This chapter discusses that pre-combustion de-carbonization (PCDC) has been identified as promising concept to capture CO 2 in power generation systems. Membrane reactors are expected to play a key role in the development in novel PCDC schemes, next to gas turbines and fuel cells. It focuses on the application of membrane reactors with hydrogen separating membranes. A generalized layout of systems for power production with H 2 membranes is discussed. An analysis revealed that the systems all exhibited certain key elements, with several options to fulfill the function in that element. The combination of a shift membrane burner (SMB) and an SOFC offer the possibility for high-efficiency power generation with CO 2 capture. The impact of the fuel efficiency on the system efficiency and key system parameters is discussed. Optimum efficiency was found at a fuel utilization of 75.5%. The integration of a membrane reformer (MREF) in a gas turbine cycle offers the possibility for power production with a low carbon capture penalty. The results of an economic analysis are provided, which give targets for membrane development. The membrane flux target is 50-100 kW/m 2 at corresponding membrane costs of 700-1400 €/m 2 .
