Bartholomew, C. H.

During the ninth quarter, progress was made toward completion of a system manual for the automated Berty reactor system; system testing was also initiated. More accurate molar response factors and retention time data were developed from calibration gases for chromatographic analysis of products during activity/selectivity runs. CO hydrogenation activity/selectivity tests were conducted on a new alumina-promoted iron catalyst Fe-A-201 at a H{sub 2}/CO ratio of 3 in the temperature range of 200--230{degree}C over a period of 150 hours. The specific activity of this catalyst was the same within experimental error as previously tested unsupported, unpromoted iron catalysts; however, this new alumina-promoted catalyst was found to have greater thermal stability against sintering upon rereduction in hydrogen. Long term tests are consistent with loss of specific activity and an increase in methane selectivity due to carbon deposition after reaction at 230{degree}C. 48 refs., 8 figs., 3 tabs.
