Summary:FTS (Fischer-Tropsch synthesis) is a catalytic reaction process for production of high value-added chemicals such as lower olefins, LAO (linear α-olefins), and synthetic waxes from waste wood, waste plastics, natural/shale gas, and even water and carbon dioxide via syngas (CO + H2). This process has flexibility in the major products depending on the demand. By-products of this process, e.g. naphtha and low-pollutant diesel, can be also used in petrochemical and energy industry. Conventional FTS processes have used different combinations of catalysts and reactors depending on the desired products. As a result, in the conventional FTS processes, once the users choose the combination of catalysts and reactors, they cannot change the portfolio of major products. Also, conventional FTS catalysts require pre-activation treatments under particular conditions, which leads to increase of installation and/or operation cost of FTS. KIER SponCatTM is a unique catalyst technology for the use of commercial type slurry bubble column reactors, which generates spontaneous and quick catalyst activation in the reaction condition without requiring an extra catalyst pre-activation treatment. Furthermore, the KIER SponCatTM can offer tunable selectivity of high value-added chemicals, linear -olefins and synthetic waxes, simply by adjusting the catalyst formulation and reaction condition. Therefore, the users of KIER SponCatTM technology can save a licensing fee and installation costs for new reactors when they want to change or extend the product portfolio.
