摘要
利用高性能催化剂将煤基合成气制成低碳混合醇成为煤基合成气利用的新方向,催化剂的选择成为合成反应的关键。介绍了改性甲醇合成催化剂、改性Fischer-Tropsch合成催化剂以及贵金属铑基催化剂等催化剂及其特点。作为Fischer-Tropsch合成催化剂之一的Cu-Fe基催化剂因成本低、反应条件温和、具有较高的活性、醇和C2+醇选择性而被广泛应用。重点介绍了Cu-Fe基催化剂的催化反应机理,以及主组分、助剂、载体类型和制备方法对其催化性能的影响。
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.
