STACProject Information CenterDevelopment of a Pilot Scale Module for Hydrogen SeparationThe objective of this research effort by New York State Energy Research & Development Authority and North Carolina State Energy Office in collaboration with Research Triangle Institute (RTI) and Pall Corporation, is to advance RTI’s palladium alloy-based hydrogen separation membrane technology to a pilot-scale module. This project will develop substrate media with optimal pore size distribution combining the best features of both porous ceramic and porous metal substrates. Membrane synthesis parameters will be optimized to reduce the cost of the Pd-alloy/substrate composite hydrogen separation membranes below $100/ft2 while meeting the hydrogen flux and selectivity targets as well as to make them robust, long-term durable, and tolerant to impurities including sulfur species. The membrane technology will be scaled up to a pilot-scale module, with hydrogen production and separation capacity of ~ 50 std. liters/min. 2. Hydrogen separation with high flux and selectivity has been demonstrated at RTI with dense, defect-free, thin film palladium-alloy composite membranes prepared by electroless plating technique. Commercially available 10-inch long porous ceramic Membralox® as well as porous ceramic/metal composite AccuSep® tubes were used in these studies as substrates for Pd-alloy film deposition. To meet NASEO’s membrane hydrogen flux (200 scfh/ft2 or ~100 sccm/cm2 at 400 oC and 20 psi hydrogen partial pressure differential) as well as cost (< $100/ft2) targets, and to achieve long-term durability, the palladium alloy film thickness needs to be small (estimated to be < 2 μm,) yet defect-free with strong adherence to the substrate surface. Optimization of the substrate characteristics as well as membrane synthesis parameters is needed to meet the technical and cost targets of the hydrogen separation membrane. The proposed membrane development effort will be conducted in four tasks over two-years.
