OSTI ID:5538748
The effects of addition during synthesis of C/sub 2/, C/sub 4/, C/sub 6/, C/sub 10/ or C/sub 20/, normal 1-olefins, was studied in a continuous well-stirred liquid phase reactor. Studies were at 248/sup 0/C and 0.78 to 1.48 MPa, using a reduced fused magnetite catalyst containing potassium. Incorporation of these olefins into growing chains could be detected, but was relatively minor. Instead the olefin was hydrogenated to the corresponding paraffin or isomerized to the 2-olefin. Excluding ethylene, which is unusually reactive, the reactivity of the olefins increased with molecular weight. Disappearance of all added species was much less at low synthesis conversions than at high, attributed to competitive adsorption with CO. The reactions of added ethanol were also studied. Ethanol or ethylene decreased the hydrogenation capabilities of the catalyst as reflected in decreased formation of CH/sub 4/ and increased olefin/paraffin ratio of the products. Neither addition affected the chain growth probability, ..cap alpha... 21 refs., 11 figs., 5 tabs.
