TITLE: Mechanism of Fischer-Tropsch Synthesis on a Single Crystal Nickel Catalyst. AUTHOR: R. D. Kelley; S. Semancik. INST. AUTHOR: National Bureau of Standards, Gaithersburg, MD. LANGUAGE: English PUB. TYPE: Technical Report PUB. COUNTRY: United States SOURCE: Department of Commerce [COMNBS], 1983, 4p. NTIS ORDER NO.: PB85-197697/INW ABSTRACT: Reactions of H2 and CO over a Ni(100) model catalyst have been studied. Measurements of the surface carbon concentrations and the product yields show that, for a fixed carbon level, the amounts of higher molecular weight hydrocarbons are strongly dependent on the reactant carbon monoxide pressure, and suggest a formation mechanism that involves a CO insertion step. |
