ABSTRACT:

Our studies of the effects of adding various selected olefins during Fischer-Tropsch synthesis have now been summarized in the form of a paper for publication. The principal observations and conclusions are: In studies with a reduced fused magnetite catalyst at 248 sup 0 C, and 0.78 to 1.48 MPa, reactions of the added species were much more significant at high synthesis conversions where the relatively lower partial pressure of CO allowed competitive adsorption effects with CO to become more important. Ethanol decreased hydrogenation capabilities of the catalyst as reflected in lower CH sub 4 formation and higher olefin-paraffin ratio.  Excluding ethylene, which is unusually reactive, the reactivity of an 1-olefin increased with molecular weight, but almost exclusively to form the corresponding paraffin or beta -olefin. Incorporation of olefins into growing chains was relatively small. (ERA citation 12:045187)
