The report describes and compares current projects sponsored by EPA and the U.S. Energy Research and Development Administration (ERDA), relating to the control of particulate matter in fuel gas streams at high temperatures (1000 to 2000F) and high pressures (5 atm and greater). The descriptions document each project (indicating the sponsor, contractor, funding, project officer, duration, and milestones) and provide a narrative statement of objectives and technology involved. Project descriptions provide bases for identifying overlap or duplication, and indicate areas not addressed by either Agency. Descriptions were obtained from documentation provided by the two Agencies and from discussions with Agency contractor representatives. Comparison of EPA and ERDA activities for possible overlap and omissions is summarized in the conclusions which indicate that there is little evidence of any overlap or duplication. Since the composite effort of both Agencies is not large, some important areas of interest are not addressed. No projects are dedicated exclusively to characterization and study of aerosol mechanics; however, one such EPA-sponsored study was completed recently. Some characterization work is done at ERDA, incident to advanced energy systems development. Development of instrumentation is limited and does not extend to the expected 1000-psig operating range.
