| Abstract: | The synthesis of low carbon mixed alcohols from syngas with high performance catalysts provides a new use pattern of syngas. The catalyst plays an important part in synthetic reaction. Introduce modified methanol catalysts, modified Fischer-Tropseh catalysts and rhodium-based catalysts. As one of the modified Fischer-Tropsch catalysts, Cu-Fe based catalysts are widely used for low cost, mild reaction condition ,high activity and great alcohol and C2＋ OH selectivity. Introduce the function mechanism of Cu- Fe based catalysts, and the influence of main components, promoters, carders and preparation methods on their performance. |
