摘要
铁催化剂是一种重要的费托合成的催化剂。Fischer等人发现将碱金属加入铁催化剂中可提高合成速率和改进反应选择性。许多研究者研究了铁催化剂中添加钾对催化性能、动力学、产物分布和化学吸附的影响.作者应用玻璃吸附装置测定了CO和H_2在浆态相费-托合成用的无载体沉淀铁催化剂上的化学吸附,进而考察了添加钾对催化剂化学性能的影响.
The iron catalyst is an important catalyst for Fischer-Tropsch synthesis reaction. Fischer etc. found that the addition of alkali metal into ir on catalyst may increase synthesis rate and improve selectivity of the reaction. A number of scientists have studied the effects of adding potassium into iron catalyst on the catalytic performance, kinetics, product distribution and chemisorption. The author measured chemisorption of CO and H_2 on unsupported precipitated iron catalysts by using a classic glass-made chemisorption unit. The effect of potassium addition on chemical pr -operties of the catalysts was also studied.
