Abstract
The purpose of the current project is to use the technology base available at ORGDP to develop membranes that will be of significant economic value to the nation for the economical use of fossil energy materials. The first part of the project will be directed toward fabricating a membrane to separate hydrogen from the synthetic gas produced by coal gasification processes. Later efforts will be directed toward tailoring membranes to eliminate the acid gases, such as sulfur and nitrogen oxides and hydrogen sulfide, from gasified coal. Project activities during FY 1989 focused primarily on developing small pore size ceramic membranes and developing a model for transport of various gases of interest through such membranes. As membranes having smaller pore size were produced and tested the need to improve the resolution of some of the test systems was recognized and such improvements were implemented. This report summarizes project activities during FY 1989 related to the three main areas of endeavor: development of a transport model for gas separation, development of small pore size ceramic membranes, and improvement of tests used to characterize the membranes. 2 refs., 2 figs., 2 tabs.
