Abstract: In this thesis,propylene epoxidation catalyzed by TS-1 in external airlift reactors was studied. Firstly,the operation parameters were investigated so as to achieve higher yield of propylene oxide per gram catalyst. The optimum results were as follows:The optimum catalyst content was 3%, the preferred liquid and gas flow rates were 2 times of 720mL.h~(-1) and 290mL.min~(-1) respectively.Secondly,the study of the influence of geometry parameter A _r/ A _d was carried out. Under the same ratio of reactor volume to liquid inlet flow rate, conversion, selectivity and yield of propylene oxide per gram catalyst decreased when A _r/ A _d increased. At the same liquid inlet flow rate, the result that conversion,selectivity reduce at a higher degree was obtained,which proved that mass transfer influenced the propylene epoxidation and the mass transfer was affected more by apparent gas velocity than by reaction time.
