【Abstract】 The liquid circulation velocities in a three phase thermosyphonic reactor for propylene epoxidation were studied under simulation reaction conditions of propylene/methanol (isopropanol,propanetriol) containing water/TS 1 zeolite.The relationship of liquid circulation velocity was correlated well with these influential factors such as superficial gas velocity,flow rate of feed liquid, temperature,temperature difference,properties of gas and liquid,and solid holdup.更多还原
