摘要
合成气(CO,H2)经费托合成转化为清洁液体燃料和化学品的工艺过程,符合我国能源发展战略,但该反应存在目标产物选择性低,CO2 等副产物选择性高的问题.调节催化剂表面的亲疏性是常用的催化剂改性方法,对调节产物分布具有重要意义.简述了亲疏改性催化剂在费托合成反应中的反应行为,系统总结了H2O对反应活性、产物选择性以及催化剂稳定性等的影响,并对费托合成催化剂表面亲疏水调变策略研究进行了展望.
Abstract
The catalytic conversion of syngas(CO/H2)via Fischer-Tropsch synthesis to produce liquid fuels and chemicals is a crucial process in the context of energy development in China.However,this reaction faces challenges such as low selectivity for target products and high selectivity for by-products like CO2.Modifying the hydrophilic and hydrophobic properties of catalyst surfaces is a common method to influence product distribution significantly.This paper reviews the behavior of catalysts with hydrophilic and hydrophobic modifications in Fischer-Tropsch synthesis.It systematically summarizes the effects of water on reaction activity,product selectivity,and catalyst stability.Additionally,it discusses future research directions for strategies to modify the hydrophilic and hydrophobic properties of Fischer-Tropsch synthesis catalysts.
