ADVANCES IN HYDROPHOBIC CATALYSTS FOR FISCHER-TROPSCH SYNTHESIS

Abstract

Abstract: Fischer-Tropsch synthesis (FTS) technology can convert coal and biomass-based syngas into high-value fuels and chemicals, which is important for achieving efficient use of carbon resources. However, water generated during the reaction process leads to side reactions such as water gas shift (WGS), which will affect the catalyst activity, stability and target product selectivity. By increasing the hydrophobicity of the catalyst, the removal rate of water can be significantly accelerated, the negative impact of water can be reduced, and the performance of FTS reaction can be improved. Focusing on the specific effects of by-product water on FTS reaction, the types of hydrophobic Fischer-Tropsch catalysts, preparation methods and principles of action were outlined, and the prospects for their development were prospected.

Key words: Fischer-Tropsch synthesis, hydrophobic catalyst, water, water gas shift reaction
