Development of a stable cobalt-ruthenium Fischer-Tropsch catalyst. Technical progress report No. 10, January 1, 1992--March 31, 1992
In this report, and the three before it, progress has been reviewed toward finding a support for cobalt/ruthenium-based Fischer-Tropsch catalysts. Of the support materials investigated three have so far shown promise: magnesium oxide, carbon and 50/50 alumina/titania. However, as yet catalysts supported on these three materials have proven inferior to the reference TC 211 Y zeolite-supported catalyst with regard to both activity and selectivity. Ruthenium is considered to be a promoter of activity, however, if this effect is manifested in the experimental catalysts it is not enough to make the catalysts more active than the ruthenium-free reference catalyst. The advantages due to reverse micelle are, so far, minimal at best. When the experimental catalysts were operated at higher conversions through evaluation at Conditions 2 and 3, the magnesium oxide-supported catalysts appeared to be closest to the desired low methane selectivity of the reference catalyst at similar conversion. The catalysts prepared on the above supports were not superior to the reference catalyst TC 211. Since the main objective of the current contract is to determine whether cobalt/ruthenium catalysts can be prepared which are superior to cobalt only catalysts, the Y zeolite support will be used in the future. In this special Y zeolite-derived support crystallite size is controlled by the pore size distribution. Thus, the catalyst development objective of controlling the crystallite size will be achieved. In the following quarters, work carried out on the cobalt and cobalt/ruthenium catalysts supported on the Y zeolite-derived support will be reported.
