Support Modification on the Catalytic Performance of Co/SiO₂ Catalyst in Fisher-Tropsch Synthesis

Abstract:

The effects of support modification on cobalt based catalysts in Fischer-Tropsch synthesis were investigated. Part of silica support was modified with ammonia solution and the other part not. The Co/SiO₂ catalyst with the support surface modified by ammonia solution showed larger particle size, strong Co-Si interaction, higher activity and selectivity in Fischer-Tropsch synthesis. It could be concluded that the support acidity can be controlled thus affected the reaction property of the catalysts in Fischer-Tropsch synthesis.
