Preparation and characterization of composite membrane for high temperature gas separation. Quarterly technical report, September 1--November 30, 1994

Description: To develop a new class of permselective inorganic membranes, the authors have identified electroless plating as a potential route to deposit a thin metal film on a porous substrate. Electroless plating is a controlled autocatalytic deposition of continuous film on the surface of a substrate by the interactions of a metal salt and a chemical reducing agent. This method can give thin films of metals, alloys and composites on both conducting and nonconducting surfaces. The objective of this projec… more

Preparation and characterization of composite membrane for high temperature gas separation

Description: A new class of perm-selective inorganic membrane was developed by electroless deposition of palladium thin-film on a microporous {alpha}-alumina ceramic substrate ({phi}39 mm x 2 mm thickness, nominal pore size 150 nm and open porosity {approx} 42 %). The new membrane was characterized by Scanning Electron Micrography (SEM), Energy Dispersive X-ray Analysis (EDX) and conducting permeability experiments with hydrogen, helium, argon and carbon dioxide at temperatures from 473 K to 673 K and feed … more

Preparation and characterization of composite membrane for high temperature gas separation

Description: The objective of this project is to develop thin film palladium membranes for separation of hydrogen in high temperature applications. The authors plan to use electroless plating to deposit thin palladium films on microporous ceramic and silver substrates and then characterize the membrane in terms of permeability and selectivity for gas separation. To accomplish the research objective, the project requires three tasks: Development of a process for composite membrane fabrication; Characterizati… more

Preparation and characterization of composite membrane for high temperature gas separation. Quarterly technical report, December 1, 1996--February 28, 1997

Description: To develop a new class of permselective inorganic membranes, the authors have identified electroless plating as a potential route to deposit a thin metal film on a porous substrate. Electroless plating is a controlled autocatalytic deposition of continuous film on the surface of a substrate by the interactions of a metal salt and a chemical reducing agent.

Preparation and Char Characterization of Composite Membrane for High Temperature Gas Separation.

Description: A palladium-ceramic composite membrane was developed by electroless deposition of palladium on microporous ceramic substrate. By measuring the permeation characteristics of pure and mixed gases, it was found that the new membrane has a very high permeability and selectivity for hydrogen. During this reporting period, a concurrent flow model for a membrane module was developed to study the performance of palladium-ceramic composite membranes for hydrogen separation in terms of product purity und… more

Separation of hydrogen using thin film palladium-ceramic composite membrane

Description: The primary objective of this study was to prepare and characterize a hydrogen permselective palladium-ceramic composite membrane for high temperature gas separations and catalytic membrane reactors. Electroless plating method was used as a potential route to deposit a thin palladium film on microporous ceramic substrate. The objectives of the work presented here were to characterize the new Pd-ceramic composite membrane by SEM and EDX analysis and to carry out fundamental permeability measurem… more
