In collaboration with Sasol Technology UK Ltd, the research team have previously used INS to investigate the surface chemistry of synthesis gas (CO + H2) over a series of industrial grade iron based Fischer-Tropsch synthesis (FTS) catalysts. It is now timely and opportune to extend those studies to examine cobalt based catalysts. Despite the wide application of Co FTS catalysts for the production of sulfur-free diesel, there is a paucity of understanding as to how hydrogen is partitioned within Co catalysts. By means of initiating this new economically relevant study, for the first time, we propose to use INS to examine the chemisorption of dihydrogen over a Raney Co catalyst; the intention being to build on an earlier study of dihydrogen over a Raney Ni catalyst.
