摘要：

The rate of synthesis gas consumption over a cobalt Fischer-Tropsch catalyst was measured in a well-mixed, continuous-flow, slurry reactor at 220-240-degrees-C, 0.5-1.5 MPa, H-2/CO feed ratios of 1.5-3.5, and conversions of 6-68% of hydrogen and 11-73% of carbon monoxide. The inhibiting effect of carbon monoxide was determined quantitatively and a Langmuir-Hinshelwood-type equation of the following form was found to best represent the results: R(H)2+CO = Ap P(H2)-CO/(1 + bP(CO))2. The apparent activation energy was 93-95 kJ/mol. Data from previous studies on cobalt-based Fischer-Tropsch catalysts are also well correlated with this rate expression.
