Current Status of Dense Cermet Membranes for Hydrogen
Argonne National Laboratory (ANL) and the National Energy Technology Laboratory (NETL) are developing dense membranes for separating hydrogen from mixed gases, particularly product streams generated during coal gasification, methane partial-oxidation, and water-gas shift reactions. Hydrogen separation with these membranes is nongalvanic, i.e., it does not use electrodes or an external power sup...
متن کاملDense Ceramic Membranes for Hydrogen Separation
In the 1980s and 1990s, the development of oxygen ion conductors for solid electrolytes, as well as mixed oxygen–electron conductors as electrodes for solid oxide fuel cells, brought scientists to envision a possibility of mixed-conducting oxygenpermeable ceramic membranes. Today this field is well established, and ceramic membranes are close to implementation in processes for oxygen extraction...
متن کاملDense Ceramic Membranes for Hydrogen Separation
Novel cermet (i.e., ceramic-metal composite) membranes have been developed for separating hydrogen from product streams that are generated during coal gasification, methane partial oxidation, and watergas shift reactions. The hydrogen permeation rate in the temperature range of 600-900°C has been measured for three classes (ANL-1, -2, and -3) of cermet membranes. ANL-3 membranes provided the hi...
متن کاملDevelopment of Palladium-Alloy Membranes for Hydrogen Separation and Purification
This paper summarizes R&D activities and progress at NORAM Engineering and the University of British Columbia (UBC) on preparation and testing of thin palladium-based membranes and their applications. Most of these activities were carried out internally at NORAM, some jointly with UBC and their spin-off company, Membrane Reactor Technology (MRT) through a wide range of projects. Key results out...
متن کاملUltramicroporous Membranes for Hydrogen Separation
Fuel cell systems offer excellent efficiencies when compared to internal combustion engines, which result in reduced fuel consumption and greenhouse gas emissions. One of the areas requiring research for the success of fuel cell technology is the H2 fuel purification to reduce CO, which is a poison to fuel cells. Molecular sieve silica (MSS) membranes have a potential application in this area. ...
