Work continued on the evaluation of fluidized-bed methanation catalysts at both the bench-scale and PEDU-scale levels. In addition, assistance has been given in planning, acquisition, and assessment of the BI-GAS pilot plant operation data. Bench-scale studies included six standard life tests to evaluate 22 new fluidized-bed methanation catalysts, and one life test of samples of catalyst from PEDU Test No. 27 to determine, if possible, a reason for the decreased activity of the catalyst during the PEDU test. Of the 22 new catalysts, only one showed sufficiently high activity at normal operating temperatures to justify consideration as a PEDU test candidate; a PEDU-size sample of this catalyst was ordered. A new clear-plastic model of the PEDU methanator was constructed for the purpose of studying heat-transfer characteristics within the methanator. Initial tests agreed sutstantially with PEDU data and indicated that the axial tube location gave better heat transfer than the non-axial location. A joint study with Brigham Young University on sulfur-tolerance testing of BCR fluid-bed methanation catalysts involved an evaluation of the activity of the catalysts before and after exposure to low levels of hydrogen sulfide. Five methanation PEDU tests were conducted to evaluate further the Homer City catalyst. The results are described in the report. Analytical and data processing services continued in support of the overall program. Pilot plant activity included the determination of the viscosity of samples of Ohio No. 9 seam coal ash in conjunction with the DOE-sponsored Conoco project. In addition, viscosity determinations were made on a sample of Rosebud seam coal ash with limestone added as a flux. Minor modifications were made to the viscosimeter.
