|Abstract:||Fischer-Tropsch synthesis (FTS) converts synthesis gas, a mixture of CO and H2, into various hydrocarbons. However, supported Co catalysts are known to deactivate under realistic FTS conditions, hence, it is desirable to improve the stability of Co catalysts. The relative stability of various forms of deposited carbon and the effect of boron on the carbon deposition mechanism were evaluated. A series of Co catalyst promoted with various concentrations of boron were synthesized, characterized, and tested. No graphitic carbon could be detected on the promoted catalyst. Promotion of a 20 wt % supported Co catalyst by 0.5 wt % boron reduced the rate of deactivation by a factor of 6. This is an abstract presented at the 2009 AIChE Annual Meeting (Nashville, TN 11/8-13/2009).|
