ABSTRACT:

The first goals of this project are: (1) to understand the influence of mass transfer on the performance of Fischer-Tropsch slurry reactors, and (2) to determine the nature of carbon formed during reaction. In reaching this second goal, knowledge of the catalyst composition will be useful.  Work during the current quarter, using both an experimental bubble column slurry reactor and a well-stirred slurry reactor has shown considerable differences in the observed partial pressure dependencies on H sub 2 and CO. For both types of reactor, the rate of product formation can be represented by the expression r = kP/sub CO//sup a/P/sub H sub 2 //sup b/.  The magnitude of the exponent b is close to unity in all cases. The value of a is approx. -0.4 to -0.2 for the stirred slurry reactor, but is more positive for the bubble column reactor. This suggests that the bubble column may be operating in a regime in which the mass transfer of CO has a strong influence on the rate of CO consumption. 1 tab. (ERA citation 10:048319)
