A study of industrial Fischer-Tropsch catalysts, primarily by means of zero-applied field cobalt-59 solid-state NMR spectroscopy

The primary concem in this thesis is quantitative characterisation of metallic Co sites in industrial Cobalt(Co)-based catalysts used in the Fischer-Tropsch (FT) reaction, which is part of the Gas to Liquid process, which converts synthesis gas (a mixture of H2 and CO) to diesel via long-chain hydrocarbons. This characterisation was mainly done by means of zero-applied field Co nuclear magnetic resonance (NMR) spectroscopy that takes advantage of the fact Co is ferromagnetic and hence has a strong intemal magnetic field.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
