ABSTRACT:

In the Quarterly Report for November 1, 1982 to January 31, 1983 we presented a new and improved kinetic expression for the Fischer-Tropsch synthesis on an iron catalyst and suggested its use for kinetic modeling where information on a specific iron catalyst of interest was unavailable or inadequate. In the past it has usually been assumed that the reaction is first order in hydrogen and zero order in carbon monoxide, although it  is known that this is inadequate at high conversions. We have now prepared a brief report, copy attached, which shows the extent to which the simple first-order expression will be in error as a function of degree of conversion and other variables. The effect of conversion of H sub 2 /CO usage ratio is also presented. Our extensive series of studies comparing the Fischer-Tropsch reaction in the presence of octacosane and in phenanthrene is still being analyzed. Some of the early work was affected by small amounts of a sulfur compound in the phenanthrene used. These studies were subsequently repeated with a highly-purified phenanthrene.  The nature of the liquid clearly has an effect on the reaction that may be related at least in part to the increased solubility of H sub 2 and CO in phenanthrene.
