摘    要:研究了在多室环流反应器(MALR)中用模拟催化裂化干气和空气制乙醛的过程,考察了MALR中气含率和液体循环速率与上升室表观气速之间关系的同时,还考察了反应温度、反应压力、原料气中乙烯含量及催化剂溶液中Pd2+含量对乙烯单程转化率和乙醛选择性的影响。实验结果表明,MALR中气体流速在0.461~0.545cm/s内气含率较大,液体循环速率仅在2.5~3.2cm/s较窄的范围内变化;合成乙醛的最佳条件为:反应温度100~120℃、反应压力0.5~0.6M Pa、催化剂溶液中Pd2+质量浓度0.6~0.9g/L。

关 键 词:乙醛  乙烯  催化裂化  干气  多室环流反应器

Abstract:Synthesis process of acetaldehyde from simulated FCC dry gas(N_2 and C_2H_4)and air in a multi-component airlift loop reactor(MALR)was proposed.Effects of reaction temperature,pressure,ethylene (concentration) in feed,and palladium ion(Pd~(2+))concentration in solution on ethylene conversion per pass and on (selectivity) of acetaldehyde were invetigated.When gas velocity was 0.461—0.545cm/s,gas holdup in MALR was high and at that time liquid circulating rate changed only within a narrow range 2.5—3.2cm/s.Optimum (reaction) conditions for synthesis of acetaldehyde from simulated FCC dry gas were temperature 100—120℃,pressure 0.5—0.6MPa and concentration of palladium ion(Pd~(2+))in solution 0.6—0.9g/L.
Keywords:acetaldehyde  ethylene  fluid catalytic cracking  dry gas  multi-component airlift loop reactor
