Title: Gas generator research and development: BI-GAS process. Quarterly report, October--December 1978

Abstract

Catalysts BCR Lots No. 4120, 4121, and 4122 were subjected to an additional life test to determine more precisely the behavior of the catalysts within the temperature range of 800 to 1000/sup 0/F. On the basis of the overall results obtained, a PEDU-scale catalyst sample, based on No. 4122, was ordered from the supplier. Further bench-scale testing indicated that it should be possible to activate these catalysts adequately with a hydrogen-rich synthesis gas containing about 6% carbon monoxide (hydrogen/carbon monoxide ratio, approximately 12/1). Initial catalyst activities with this procedure were quite similar to those obtained in an earlier test when the samples were activated using pure hydrogen. On the other hand, catalyst activities did not increase significantly during the test, indicating that higher temperatures (above 950/sup 0/F) might be required in a PEDU test to achieve optimum catalyst activity. A life test of catalysts BCR Lots No. 4104, 4105, 4106, and 4107 was initiated to determine the effect on their thermal stability of adding various promoter metals to these nickel--molybdenum catalysts. Preliminary results indicate that the promoters were ineffective in enhancing thermal stability. PEDU Test No. 32 was conducted over the 5-day period of November 6 to 10, 1978. Themore » catalyst used, a noble metal-promoted nickel catalyst, was the most active of any tested to date. It also showed greater methanation selectivity tha the BI-GAS pilot plant methanation catalyst. The data show that with this catalyst it was possible to obtain a product gas meeting pipeline quality specifications in a single pass through the fluidized bed methanator, without the need for polishing methanation (and without the need for secondary carbon dioxide removal).« less
